Thank you for showing us this very fine tutorial on Schottky diodes. I already know how to test this one but kept watching your video till the end because I expected you to drop helpful tips. It was worth the time. I learnt important information about peak reverse voltage and how this particular series of diodes are named. I'm sure your explanation on how to use ohms range to test it in the absence of diode mode on the multimeter would be helpful for a lot people. What makes this tutorial special is that you put some effort to show us where each pin of the diode is connected in a real circuit board. I don't mean to criticize anyone but I find this important aspect neglected on many tutorials. It's easy to learn how to test something when it stands alone. But when it's inside the network, things become dark and cloudy. I hope you'll keep us entertained with more tutorials like this one. Thank you!
dear haseeb sir, on diode mode my uf shotky diode shows normal value but on ohms range i am getting mega ohms reverse biased while testing on table ,is it normal? but it somehow works on circuit board. i have no idea.. please help me understand
if you have ohm mode in your dvm then it is ok to verify the diode in forward and reverse direction. the same in ohm mode you may check the function same as in diode mode
I have a Dr Meter PS 3010-F 30v 10a bench power supply. It won't produce any output. Every once in awhile it will come on but the LEDs for the current and voltage flash off and on and there is an surface mount LED on the board that is on but it pulses from bright to dim. I've checked these and I think they are good. What could be the issue. Can't find anything on repair. Please help I can't afford a new one and need it asap.
it means your smps controller ic is not receiving feedback. please cehck the secondary section for any short or leak capacitor or short diode rectifier check tl431 circuit might be some over voltage or over current protection is interrupting the circuit
@@HaseebElectronics ok thank you. So do heat sinks usually registrar voltage? Mine reads 172.5 and I accidentally grabbed it that's how I figured to put a multimeter on it. I'm literally learning electronics so be easy on me. I may film a short video and post it. I'm willing to trade 3D graphics or 2D graphics to anyone who can help me with this. I know time is money and I'm out of both but I am a good 3D artist and can trade.
Hi again my only question my shottsky Diode 3 pin when in cct the anodes are connected forward bias so it reads continuous so when removed from cct it is open cct betwwn the anodes which is correct. I have one where anodeswhich reads open in cct. I think one is faulty. Please advise. Thank you
Thank you kindly, I'm working on an smps from a power speakers, some of the diodes get about .5v one way and 2.5v the other way , they are US1D and RS1D, I have some spare PCB's and I found some ES1D on it, same voltage and amperage and Vf , can I harvest them? also, all the caps on the low side that are rated 470µf, are reading 430 to 440µf, is that close enough or do they need to be replaced? thank you again. The original problem was I was getting power to the primary, but nothing after that. I accidentally shorted the rectifier while testing and waiting on replacements, but that was I got before the magic smoke. thank you again.

very helpfull. i have mbr20100ct, when test in diode mode its show normal. but when use ohm its value is small and when check the right and left pin it give ohm and back to ol. is it bad one?
mbr1010 is 10 ampere 1000 volt bridge rectifier . if you are asking for bridge rectifier then use MBR1510 or MBR2510 MBR10100 is Schottky rectifier. if you are looking for MBR10100 then you can use MBR10200, or MBR15100
no rfu20tm5s is recovery diode. that have only one diode inside. center pin is cathode, and outer both pins are Anode pins. outer both pins are connected to each other.
AOA sir main ne 10 amp battery charger repair kia Hy ab dc capacitor pe 14 v out ho rahy hen Lekin output leads pe ni Kahan pe issue ho skta Hy plz repy
@@HaseebElectronics Thank you for replying on my comment fast. That's unfortunate I bought it hoping that I can replace the broken diode but having a second thought that it might not work and will result to damage the other component. So I asked you. Again thank you.
@@HaseebElectronics hello again my friend. I tried it but the result is unexpected. All components are working fine but when test the output voltage I only got 12v instead of 20. So maybe that diode is for 12v only.
Worth watching video. Thank you very much. Are there any two terminal schottky diodes? Which diodes are used in the output circuit of SMPS transformer?
hello sir, i have a STPS3045CT dual schottky rectifier, and i got 0.101v voltage drop on each to pin, and no reading in reverse, is 0.101v voltage drop normal? thank u
Hi! Where may I find in my MOSPEC S20C40C Datasheet , the normal drop voltage between anode and cathode??? This, when you are measuring the component apart from the circuit. I have a reading of o.167 aprox in both sides. Greetings!
datasheetspdf.com/pdf-file/366136/MospecSemiconductor/S20C40/1 black lead of ohm meter at center pin (Cathode K) to both outer pins (Anode Pins by connecting Red Lead) it is normal reading, because it is Schottky Barrier Rectifier by reversing the test leads multimeter should display OPEN
@@HaseebElectronics it displays open luckily. May I change the entire 3 components of the heatsink independently if they are ok or not? Or maybe just the broken ones?
@@HaseebElectronics thank you! Also, I was wondering, is there any tester or maybe a homemade tool , to connect the power supply to this tool and then the tool to the wall supply (220v in my case)??? So that, to prevent the ATX power supply blow up if anything is bad fixed.
@@abofares2261 simple diode have 0.7 volt drop. so it will cause to drop voltage, and will reduce converter efficiency due to low recovery at high frequency, it will case to dissipate more power, and will damage faster so we have to replace with schottkey diode simple diode will work but it will damage faster
thanks a lot CTB-34M is center-tapped Schottky Barrier Diodes (Center-tap) center pin is cathode, with heat sink it is 40V 30 Ampere while CTB-34 is 40V 15 Ampere
I am having MBR20100P in imax B6. But I can't able to find that in market. Can I use MBR20100CT instead of. And can you tell me what is CT and P and all meant?
Best description of how a Schottky diode works that I have ever seen.

Great video,I have HBR20200 doe s this mean HBR20100 cannot be used.
hi hanks excellent explanation ! Ill put it to good use
Thanks very nice can’t use 2 diode for replacement this device ??
Yes you can 2 schottky in place of this one
very helpfull.
i have mbr20100ct, when test in diode mode its show normal. but when use ohm its value is small and when check the right and left pin it give ohm and back to ol. is it bad one?
it is schottky rectifier,

Mbr3045st ki jagah aur kaun sa diode lagaye sir
Same way of testing on MUR1640CA?
The X4202S is not availavble, may i use the mbr2040 instead?
No
X4202S is 20 ampere 200V fast recovery freewheeling diode
while MBR2040 is 20 Ampere 40V is a schottky rectifier
so it will not work
How to find equivalent for MBR1010 shottsky.thank you
mbr1010 is 10 ampere 1000 volt bridge rectifier . if you are asking for bridge rectifier then use MBR1510 or MBR2510
MBR10100 is Schottky rectifier. if you are looking for MBR10100 then you can use MBR10200, or MBR15100
Thanks for sharing this amazing tutorial on function and testing of rectifier 👍♥

hi, do i need to remove it from the board to test it? thanks
it is better to remove and test it outside to eliminate the problem
Thank you very much for the info!
It reminds me the schematic of the pnp transistor on your previous video about transistor identification.
How about rfu20tm5s.....its same with this video.....how i know this transistor good or bad
no rfu20tm5s is recovery diode. that have only one diode inside. center pin is cathode, and outer both pins are Anode pins. outer both pins are connected to each other.

No two terminals skohtty, the are just called diodes at that point. The 3 are are high speed rectifier diodes
It depends on the PSU. Or inverters your working on. Plenty of different types of diodes and Mosfet bridge rectifier and rectifier diodes ECT.
