- This is a demonstration of some of the capabilities of the Peak Atlas DCA Pro (model DCA75) made by Peak Electronic Design Ltd in the UK.
A selection of parts is shown being tested here, there are many more parts that can be tested and there are indeed some parts that can't currently be tested.
The DCA Pro adds considerable features to the capabilities of the popular DCA55, such as USB connectivity (allowing simple low current, low voltage curve tracing), a graphic screen (showing component symbols) and an enhanced analysis portfolio.
Some types of parts that we know that it can't currently analyse (as of Feb 2013) include unijunction transistors, triacs and thyristors that need more than 10mA, and voltage regulators that are not stable without their decoupling components. Additionally, Zener support extends to nearly 12V and voltage regulator support extends to around 8V.
The DCA Pro comes with an alkaline AAA battery, comprehensive printed user guide, USB cable and PC software on a Peak USB flash drive. PC software updates and instrument firmware updates are provided frequently offering continual enhancements, new features, extra component support, new curve types and other improvements. Power is provided by single internal AAA cell and/or USB power.
We do our best to respond to feedback and we try to implement feature requests when possible. THE best way to contact us is by using the email link on www.peakelec.co.uk/content/contact.html.
Everything we do is designed and manufactured in the UK and carries a 24 month warranty.

PeakAtlas, indeed a great and affordable product proudly made it in UK. My respects and congratulations.
Hi Musthafa. Thank you for your question. Yes, the DCA75 can test most types of IGBTs including depletion mode and enhancement mode varieties. You can attach the 3 test leads any way round and the DCA75 will give you lots of information including: IGBT type, pinout, input threshold voltages and transconductance (gain).
Love your products!! Got me a ESR60, DCA55 and LCR40 couple of years ago and have now ordered this DCA Pro. Cant wait to try it out, keep up the good work!!
Hi Sivucit, thank you very much for your comments. I hope you enjoy using your new instruments. Generally, if possible, it is best to test out-of-circuit to avoid the effects of the surrounding circuitry. For 2-leaded components you need to remove 1 lead from the circuit. For 3-lead components you need to remove 2 leads from the circuit. The Atlas ESR can be used to test ESR in-circuit as the capacitor's ESR usually dominates the measurements, so that is the exception :-)
Yes, I've tested many 2N3055 transistors (one of my favorites for building PSUs in fact). There are many indications of a "good" transistor so you can decide if you need to investigate further or not. Gain, Vbe and Leakage are all good indicators of transistor condition. The DCA75 is great for matching devices, you can use the device "stand alone" or use the curve tracing capability to superimpose the curves for different devices on top of each other to check for matching.
Great videos, it's good to see something designed and MADE in UK. A very handy bit of kit - I will be buying one soon.
Thanks Tony. We are very proud (and determined) to do everything in the UK. Even our plastic mouldings are UK made.
@@PeakAtlas Hi, mine fail after 6 years of intense use.
Battery leakege damage the wires, I change the battery contacts, wires and USB port but meter starting failing identifying emitter and colector, some times fail testing IGBT's or mosfets.
Now I bought a new one but I want to try something for fixing.
Any Idea?
That's good news, glad you like it. We are looking at the possibility!
Very detailed video, thanks
I'm really happy with the DCA75: it is so easy to use and it reveals so much information. It's just excellent. Please do consider engineering a valve curve tracer!
Thank you for your comment. I'm delighted you like your Peak products. Do update me on your thoughts of your new DCA Pro when you've had a good test.
Thank you for your comment Mike, much appreciated.
I have to get one of those. Extremely useful for repair jobs. However I would rather have it in a (bench) multimeter enclosure, but that is just personal preference.
Thanks for the quick response, GND to VOUT alone measure like a zener. There is not short nor open in my device so I think it is good.
Hi Miguel, thanks for your question. Some regulators aren't happy when being tested outside their usual circuit of decoupling caps, minimum load etc. This is discussed a little more on Page 28 of the user guide.
Some regulators can be "tamed" a little by placing a 0.1uF capacitor between GND and VOUT of the regulator. I tried that on a 79L05 today and it then measured it correctly. So in answer to your question, it's possible that your regulator is ok even if it's not detected.
Fantastic Jez, I do wish you had been working on our projects !
Thank you for your comment David.
Thank you for your comment, much appreciated. We're always working on development, keep your eye on our website.
A great piece of equipment
Hi Glenn, that's a good suggestion, I'll see what I can do.
Generally, if it displays that it has found a particular component type then it's a working component. You can then decide if the detailed specs that it shows are good enough for your intended application. For example, a transistor may be working but have quite low gain, so you'd reject it on those grounds. If a component is completely dud then the unit may say that a working component has not been found, or a short circuit has been detected, or possibly a PN junction or 2 have been detected.
We recommend that testing out-of-circuit is the best bet as it's not possible for us to know the influence of the surrounding circuitry (imagine how a transistor would look with a low value resistor across two of it's legs). Sometimes you'll get away with it and you can test in-circuit, but it's not a good idea generally. Also, there is more danger of damaging the instrument if there are charged capacitors or power on the circuit. We know it's not always easy, but out-of-circuit testing is best.
You are really a pioneer this is the future of test equipment, small, cheap and usefull. Are you working on any other new projects that will be released soon?
Not sure what's happened to previous comments. Apologies to those who left comments. I'm investigating....
Hi Silvaraj, sorry, we don't currently have anything suitable for testing ICs. I believe Farnell and RS sell something for ICs though, it was a while ago when I last spotted it. Worth another look I think.
I have an ESR-70 and it's invaluable for PCB repair. I think this unit will be next.
The ESR70 is great for PCB repair. I used mine to repair a '70s amp and an '80s scope recently. Even modern gear like TVs and PCs suffer from failed electrolytics, things designed to the absolute limit sometimes.
PeakAtlas I picked up a DCA75 and while it's amazing I think it may be more than I need. The DCA55 is probably the right unit for me for specific semiconductor ID and also to give me a more definitive "good/bad" indication.
Great video,
A follow up video with leaky, shorted or open junctions would be helpful. When I buy devices, I have already looked at the data sheet and see little value in confirming the OEM data.
However, more info about the troubleshooting capability would add much value and help justify the cost.
Regards,
Glenn

Very well presented, great video, ordered one, how can you not buy one after watching this! A1
With a little experience you will find that it is not necessary to test every component on a board in order to find a fault. You should be able to "narrow down" the areas that are most likely to be faulty (depending on t he circuit operation) and then test only a few parts to find the faulty one.
Hi, I have a 15KE220CA (Transient Voltage supressor) I have one bad and the peak atlas detected a Short. The new one said: no component detected. Good news I did replaced it in the power supply of a Toshiba TV and I fixed it.
Hi,
i was wondering if there is a chance of having some batch testing of devices. So if you want to match a big number of, e.g. JFETs for same IDSS, you might want to simply plug those in one after another having enumerated them, and then the measurement might be automatically transfered by the PC program to an excel sheet which then can be used for bundled matched parts. I guess this can be done with a firmware update. Is there a chance to have such a feature or is it already there?
Thanks for this cool little device,
Walter
I bought one recently,I am very happy with it. I am testing a voltage reg. the LM79M05CT and it said no component detected. Does that meas the Regulator is bad?
Glad to hear it! If you haven't got one yet then there's nothing to lose by ordering one. If you don't like it for any reason then you can return it for a refund. I suspect you'd love it though. Buy from our great distributors or from us directly.
There is an issue where it can not detect some voltage regulators. Pretty important fault if you ask me. Please see the 'KainkaLabs' review. I'll wait for updated version of this model.
The DCA75 is currently able to measure HFE up to 32000 (increased from original spec of 20000). If we're able to increase this further in the future then we will.
Do you have a video on how to change out the leads on the atlas pro.
Thanks I bought DCA 75 pro, LCR and ESRMETER, all the three. one of the main reason is your prompt answer.. I was about by BK, then changed my mind.
I am a new bie to electronics.. if I want to test the circuit, let say I have 30 components, do I need to remove all those 30 components to test one after another to find faults. I can use ESR to verify capacitor in circuit, do u have any suggestion or book that u refer that will help to diagnose. 2) can I use ESR to test 50 MFD CAPCACITOR
I need to match 2n3055 transistors for my old seeburg jukebox SHP amp. Also the amp has 32volts going to these power transistors. Can this meter determine if transistors are good and also match new ones? Thanks.
Hi, dca 75 can take the test in the IGBTs equipped with diode ?
Hi, do I need to remove the component from the circuit to test or it can be tested in the circuit .. example, mosfet, transistor, triac, voltage regulator etc in the circuit. Thanks for ur help.
Can I use this to match irfp260n mosfets I have a mega328 tester and not liking the results
I want one!
Hi, i would be interested in the PEAK DCA75 but i need to know if there are some limit as regard the testing of IGBT and MOSFET.
Can every IGBT and MOSFET be tested?
Regards
Gaetano
This is great. Really wise and well-designed tool. Is it possible to get a Mac software?
Currently we don't have any Mac software for the DCA75 although I have heard from one customer who did manage to get the PC software to run on their Mac using emulation. It's not something we can advise on though as we haven't done that ourselves.
i just wanted to see mosfet curves , for example irfz44n
I have a request for some extra functionality to the plotting tool and a question for a more advanced curve tracer.
1) Could you guys add some functionality to plot a dc & ac load line within the current Ic/Ib, Vce plot window and also add the ability to plot a power curve for your device?
2) Are you guys planning on developing a more advanced version of the curve tracer? I.e. with an external power supply - for larger power range- so you can test devices at their limits and really use this tool as a design aid?
Thank you.
Totally agree with you
Please a signature analyzer.
hi, do u have any instrument to test IC if not is there a way to test with pin our chart or scope.. any recommendation, pls
Hi, it looks very interesting. Can I match the transistors pairs with this one successfully? How the device react for temperature changes in the matching proces?
The DCA75 is great for matching transistors. You can can measure both hFE and the base-emitter voltage (which are often needed for matching). Furthermore, you can overlay whole graphs on top of each other to determine a good match for your own personal requirements. Both gain and Vbe are very temperature sensitive on transistors of course, so you need to ensure minimum handling of the transistors and allow time for the transistor temperatures to settle to ambient before testing. These are fundamental characteristics of semiconductors and not the DCA75.
@@PeakAtlas Bought it already, great tool indeed ;)
I have the DCA75. Unfortunately the right hand side of the dot matrix LCD display has started to fade making the info displayed there unreadable. Is it possible you can sell me a replacement display, and I'll change it out?
Very informative documentary and very well explained on there products. Sadly I have found on the long term there products are very unreliable, 18 months ago I brought a Peak Atlas ESR70 and used it for 2 hour's; battary gone flat. Year ago I brought a LCR40 only used for 1/2 hour now sorry it doesn't work at all.The peak instruments were stored in mental filing cabinet in the bedroom of my house. I am bloody up set ? I brought the instrumentation from Maplin electronics in Leicester; I need them to do my every day job ?
Hi Kevin, Your Peak instruments are guaranteed for 2 years, so please send them to us for an immediate solution to the problems you've experienced. They should certainly be extremely reliable for a very long time, and we'll stand by our products to make sure that everything works for you as expected. Even after the 2 year warranty has expired, we're still happy to look after customers and their Peak instruments. Visit our website, click on the "Contact Us" tab and send your units to the address on that page, we'll soon get you up and running again.
Wau! nice addictions to the software. I like that schematic on the botton right side make the sorfware screen nice and complete. I just went to your page and got the new firmware and software. I had no idea you were releasing new firmware for this. I hope you can do other stuff like this.
Hello Miguel. Yes, the schematic can be zoomed too. We find that it is very helpful to have the schematic on the screen so you can see what can (and can't) be done with the test parameters. It also helps people to reproduce the test conditions manually on a breadboard for example..
hi, will it get pass or fail result.
Yes, it is Witchcraft.....but in a non-witchy sort of way.
If I understand correctly, the DCA Pro DOESN'T explicitly tell you if a semiconductor is Good or Bad. It gives you the operating parameters of the component (and identifies it) and then you have to compare them to the manufacturer's specifications. I guess another way to tell if the component is good or bad is to see if any of the lines on the curve traces breaks down or is distorted.
Correct. But most semiconductors fail fairly catastrophically which means the DCA Pro will tell you if it's bad rather quickly by indicating a short, no component detected or it will think a different class of device is present. (For example, a transistor with one open junction will show up as a diode.)
Can you measure germanium transistors with this device?
I've just found 25,000 pieces Newmarket NKT 275 transistors so I need to check them for leakage and gain.
Thanks in advance
Yes, the DCA75 is great for Germanium devices. It will happily measure leakage current, current gain and Vbe for your devices. Note also (unlike many multimeters) the current gain measurement is compensated for collector leakage current. Our DCA55 product does this too.
Thanks!
Hello, can you add symbol of a double diode (common cathode, common anode.) in the next update?
Hi Edgaras, thank you for your very good suggestion. We will do our best to add those symbols to the next firmware. The symbols for those components are already shown in the PC software but I agree that it would be sensible to have them also in the instrument's firmware.
My device does not recognize JFETs. What can that be?
Hi Peter. The DCA75 should be able to recognise nearly all JFET types. Please send us an email with some further details of the problem and we can check it out for you. Our contact details are on our peakelec.co.uk website.
hi peakatlas this product available in united arab emerates?
I have this unit for some time and I highly recommen it if you want to know all you can about a transistor FETs, MOSFETS fast and cheap.
Hi Miguel, thank you for your comment. Very pleased that you are getting good use from your DCA75. New features being added all the time too.
PeakAtlas What new features have been added? I have it since june last year.
By the way yesterday I used it to check a guidance circuit card that works in conjuntion with a concrete dumping device and found the problem in a dual juntion common mode anodes 3 pins device, fast and easy with IN CIRCUIT testing. Great product to do assembly line testing too I think. Just one repair pays well for the cost of this unit.
Miguel Rodriguez Yes, lots of features have been added since June 2013, too many to list here, but worth checking out the revision history on our DCA Pro support/download page.
windows, mac and Linux?
can you test components in circuit?
Generally speaking we would not recommend testing in-circuit. Sometimes you can get away with it. The influence of potentially unknow components in an unknown circuit configuration can of course affect the readings that the DCA75 is trying to take and that is impossible to compensate for. Furthermore, you can't always be sure that the circuit you're testing is completely free of stored charge and that may damage the DCA75. Another thing to remember is that if you have the DCA75 connected by USB to your PC, then a ground loop problem can occur if your equipment under test also has a route to a different ground, big currents (and failures) can then occur. So testing out of circuit is recommended and I acknowledge that is not always convenient.
yeah yer products are pretty sweet.
Glad you like them. We only make stuff that we like ourselves, so hopefully others like them too :-)
Wow! It's Witchcraft I tell ya, Witchcraft! Amazing stuff...
can u save curves to usb
Hi Kay, yes you can save curves to any storage device you like including USB flash drives. In fact you can save curves, raw sample data and also images.
@@PeakAtlas curves saved as jpg or...
Hi, I don't recognize the voltage regulators 7805, 7812 and other series. What should I do to identify?
A GOOD PIECE OF TEST GEAR FOR THE HOME HOBBIST.
Thanks Robert. Yes, I use mine for my hobby too, takes up little space which is a bonus!
can test ujt or no
Sorry, the DCA75 does not currently support UJTs.
@@PeakAtlas test voltages seem cannot be high,, such as 30v or 50v.. right
At the beginning, the screen may be clear to you but it isn't to us viewers. The camera angle does not favor clear viewing to us youtubers.
Hi Theodore, thank you for your message. We intend to produce a new video for this product (and some of our other products), we'll ensure that the screen visibility/angle is much better.
what abt rds for mosfet.... and this is only dc analysis,,,, not ac huh
Yes, the does now measure the Rds on MOSFETs, down to a resolution of around 1 Ohms.
doesnt show beta huh
Hi Kay. Yes, it shows hFE which is identical in most respects to Beta. It is also known as current gain. Both the DCA55 and the DCA75 measure hFE 👍
@@Little0tter what prices for each,, pls
can test ujt or no
Yes, the DCA75 measures beta (hFE).
It can be misleading on power MosFets do to its small battery source.
Thank you for your comment. Could you tell me what problems you are experiencing? The MOSFET driving capability shouldn't be limited by our battery size. The test voltages and currents are derived from a regulated boost voltage from the AAA cell, so can cope with gate thresholds of up to 8V.
