I just completed my multiwii quadcoptor and nrf24lo1 transmitter , works great , appreciate your contributions, it would be great if you can kick Start new project with kk2.1.5 (Arduino based ) with LCD , I not familiar with Arduino programming, however I'll provide my full support and share over internet ......
Very useful video.. can I ask that which program is used for 3d animation??
Electronoobs /Thanks...

I know it has been said before but thank you for everything you do for the IGBT community!
On that note what is an IGBT's Q?
#Resist ...err, I mean resistance
@@InsideOfMyOwnMind quad, I'm guessing. There's one component called an H-bridge, which uses 4 control inputs with a total of 4 functions. Quad means 4. The 4 functions are forward, reverse, brake, and no current.
BiPolar Bear Likes This.
Haha i laughed so hard on that
I found electronoobs channel more useful as it explain electronics deep down. Thank you for the effort. God bless you.
Wow your graph really helps to memorize the rest of the video, great work
Great review for people already family, too.
And as always, very good and informative graphics.
Thank you!! This is hands down, the best video on transistors I've come across.
Excellent video with great graphics that explain the voltage, current and frequency combination of the three different type of chips.
I have just watched 5 videos on this subject and ours is by far the best! Well done !
thank you for every information you give people!
Thank you so much, I hade one question, and unlike any of the other peeps on the TH-cam...you answered it plain and simple without giant math fractions
I’ve been crawling through the TH-cam for 2 days
I must say, this is the best video on transistors. Thank you for clearing the air!
Yeah, this video is pretty inaccurate. I'm guessing that "Electronoobs" doesn't really know anything substantial about this topic, because he completely misses out on the key differences between these devices. So, allow me:
BJT:
- CHEAP
- Robust against static discharge which makes it very popular
- High voltage capabilities (typ. 40-1000V)
- Best low noise performance when used as a linear amplifier
- When used as a saturating switch, poor turn-off behavior which limits the switching frequency to usually 20A) because the saturation voltage is roughly constant (usually .2-.5V), but...
- Requires a high-current output control driver which makes it unpopular for high current applications
- Current can only flow 1 way in the ON state, Collector->Emitter
MOSFET:
- Medium Cost
- Extremely fragile to destruction by static discharge
- Medium voltages (typ. 20-400V)
- Poor performance in linear amplifiers (nonlinear behavior, high noise)
- Extremely fast switching, easily up to 20MHz with high-power loads (and the new GaN FETs promise to be even faster)
- Efficient for low-medium currents since it behaves like a low-valued resistor
- Easy to drive since the gate is an open-circuit
- Current can flow both ways through the device in the ON state
IGBT (BJT with MOSFET gate):
- High Cost
- Fragile to destruction by static discharge (but usually less so compared to MOSFETs)
- Very high voltage, up to 4000V
- nobody uses these in linear amplifiers because it would be pointless
- switching behavior is similar to BJT, but usually slower (Emitter
So, the TLDR; is that you use BJTs for building robust interfaces since they usually don't need ESD protection, you use MOSFETs for low-medium current switches, and for really high-current switches you use IGBTs. The distinction between MOSFETs and IGBTs is basically on the basis of efficiency - the heat generated in a MOSFET increases as I^2 since it behaves like a resistor, whereas in a IGBT it increases more like Log[I]. You will have to do some math to figure out which transistor to use on a case-by-case basis.
Hope this is more helpful to people than the video was.
Colin Marcus this is exactly what I needed, thank you so much!!
@Chris Russell - UJTs are very rare... in fact I have never seen one used in a design. To my knowledge there are only 1-2 components on the market at this point, so they are pretty much extinct.
@Colin,
Thank you for the information, but you're an idiot though, have more respect when writing. Your comments about the video are disrespectful and don't appreciate the work done for the people. Otherwise, thanks for the useful info. Idiot learn some manners. Sorry had to add the last line 🤷
So where is your video? You know this is TH-cam channel. All you did is gave more information that noob doesn’t understand anyway. Why criticize someone’s work which was completely adequate for a noob? So no, your information wasn’t more helpful to a noob. It was useless. But still, thanks for effort. Thanks for sharing. Thanks for spending time to help someone.
@@Traderhood some people think they were born knowing it all it is a character trait, nothing to get one's feathers all ruffled, there's always somoene above and below 😒
Excellent presentation and production on this video! You have taken a big step up with this one!
The block graph was a perfect visual. thanks for this explanation!
I'd love to see these used in example projects. Like a full project video for each type, maybe even a few different applications.
What a great video. I loved the idea of the 3D graph @ 6:22, and the graph itself of course!
Seriously one of the best explanations I’ve heard, and I’ve heard MANY
Just great, I am studying engineering and its very important to understand that BJT can handle high voltages but low currents because when you try to use them with high currents the Saturation Voltage between Collector and Emitter increases and it implies higher power losses. MOSFETS can handle high currents once you apply around 12V to its Gate, but they have no reverse polarity protection and also can't handle high voltages, IGBTs are great for both purposes high voltage and high current but a disadvantage is that the C-E saturation voltage when you handle high currents increases and brings again higher power losses, well, perfection doesn't exist, right?
Parabéns pela explicação e aplicação, 👍Muito bom
I've learnt so much from this channel. Thank you!
Great introduction. Thanks a lot for your work!
That 3D block diagram of voltage, current, and frequency brought it all together. Thank you.
THANK YOU! Awesome! A few more practical examples would have been nice though, explaining in a little more detail when to use which type. Nevertheless, superb video!
6:26 for my future reference on project DIY. THANK YOU SO MUCH 🙏🙏🙏🙏
Thank you. It's so easy to understand. I want to travel back in time to my EE years and show this video to my Past self.
Thanks. Today is my exam. You saved me! ❤️
After all these years, finally your video explained me where to use which, thanx
Sir, your voice is so sweet.Thank you very much for giving us so precious knowledge.
Thanks for teaching
BJT/MOSFET/IGBT
BJT
High voltage and Low current
Low on losses
speed : around 100 kHz
Complex base Drive
MOSFET
High current low voltage
Low RDS(ON) resistance
speed around 500 kHz
simple gate Drive
IGBT
High voltage high current
Low on losses
speed gate Drive
Low speed around 50 kHz
Low ON losses will depend on the load current. Because some Mosfets have very low Rdson and the Collector emitter volt drop of and Igbt is around 1.2 Volts. So you should also calculate the conduction losses before deciding on Mosfet or igbt
Thank you, thank you. Love this stuff!
good educational video with some good animations
Very Great channel.. Super briefing... Love you sir...
It is a very good short video. Thanks a lot!
انت رائع 💓استمر
Buenísima la explicación ¿Que bibliografía recomiendas para tener una buena base en cuanto a los componentes? Y si tienes algún video del funcionamiento de GTO, please. Thanks.
Well simplified and explained for such electricity raw material beginners like myself, thanks mate and keep up.
I'm a beginner , but I don't understand , I'll seek for another simple explainations videos
You just made my day 👏👏
Great beginner video. I would love to see you use each of these in 3 different circuits showing 3 real-world examples of their uses.
In 4yrs of degree i couldn't understamd properly u explained easily in 10min OMG😮😮
Perfect brief explanation. Thanks.
excelente, no entiendo el ingles pero el apoyo gráfico compenso por mucho, tanks you for you work
Awesome video man thank you for your time 👍🧡
I have at home a igbt module with one defective igbt (the module have 2 for each motor phase), and I was thinking about using it to make a guitar amplifier. Since the module still have 5 working igbts and they are kinda high wattage, I could use the same module to make the amps power source, preamp and power amp stages.
Great video. So much valuable info in this video. Thanks.
Thank goodness I found this video, been looking for this brief explanation and comparison about transistors. Very nice. :-)
Watching my video
Great information summery. Thank u
Good video but I was missing a little more about the reading of a datasheet for a transistor,
e.g. what does "Continuous current rating" mean exactly and what is this entry used for?
Loved your explanation of the different components thanks for sharing, new subscriber.
Its very usefull. Thanks
I hope you will make this kind o f video for the future.
@@ezion67 i know. But something like this is very important for youtube comunity
real it is inclusive knowledge about transistor . i am delighted at your presentation n methodology . Many thanks ! Electronoobs
Awesome presentation
Loved it...
I finally understand transistors now thank you so much!!
Thanks, man. I DID need it broken down that simply...
Yet another great video 👍
Amazing video! Could have really used this back in Eng. I really liked the 3D graph to visualize the current and voltage ratings.
Thanks for your video it helps my channel grow and push me
make more, Good Job
Excellent explanation💯
Best explanation I ever seen
Excellent video! Very informative!
Really interesting! Thanks a lot! 😃
And that's why quadcopter's escs use mosfets. 😃
Very helpful video 👍 Excellent
Nice handle the subject very clearly welcome
Tq
Awesome Video , clear my base on this topic. Thanks
I am so glad you are so good and you speak perfect English. By next spring, you will be at 1M. I am 59 and no one has explained these devices as well as you have. Thanks, Noob. (I just added that (Noob) to the (my) Dictionary. Keep up the good work and be safe.
Great explanation👌
Its crystal clear. Thank you.
Very informative. Thank you
MOSFET is fine with high voltage as well. IRF840 can go up to 500V and I own few IXTF1N450 MOSFETs with a rating of 4500V and 0.9A (continuous Vds and Ids. They are incredibly expensive).
from my internship at a company that designed and built power converters , a rule of thumb I came across is that around 1000V mosfets begin to lose out to IGBTS due to the tradeoff between voltage rating/impedance. ......sounds like a incredibly specialized mosfet. very cool! (and very expensive ;-) ).
@@km5405 True. The resistance of this MOSFET is very large compared to IGBTs with similar voltage rating. The main advantage is higher on-frequency.
@Mdmchannel Yes, 4500V. It's much larger then regular MOSFETs
@Mdmchannel www.mouser.com/ProductDetail/IXYS/IXTF1N450?qs=wUaLziKAieVmbFKN0j%2FKRQ==
@Mdmchannel
IXTF1N450(4500V0.9A-MOSFET)
IXBT12N300(3000V12A-IGBT)
FGA25N120ANTDTU(1200V25A-IGBT)
IXTA-H1N200P3-HV(2000V1A-MOSFET)
IXTF02N450(4500V0.2A-MOSFET)
FGA25N120ANTDTU(1200V25A-IGBT)
The last IGBT is used in some induction cooker - you can find some costing only few dollars on amazon (not sure about quality but I guess it's fine).
These are what I got. I'm not an expert.
Think about the current / voltage / switching time / leakage current you want.
High voltage MOSFETs general have higher on-resistant. Take that 4500V MOSFET as example, the on-resistant is several hundreds of ohms but offers better switching time.
If you don't care about switching time (for example, operating within 1000 Hz) but need high current, go for IGBTs.
Read datasheets carefully when making your choice.
You can find much more on Mouser website. You have to pay more if buying from Mouser. However, if you buy on Amazon, you risk buying recycled electronic components.
This is school 👏 EXPLAINED EVERYTHING 😊
very good video, everything was clear
Thanks for the information
best comparison
Thank you for your great video 🙂☺️
Such a great video!
thank you man you are the best 😊
Great comparison.
I really love the Italian like English accent, btw you earned a new subscriber
I believe he is from Spain
Can you show with examples on breadboard for each types
Haaaay malayaliiiiii😱😱😂😂
100% Informative
Thanks for the video sir .
Thank you for this video
thank you at all. It's real usefull information
Great explanation. I have suscribed to your channel waiting for more videos
Well explained 👌
Good animations! I like it! :)
Nice tutorial!
Loved your videos
Perfect explanation Master 👍
I would have a question:
- I built several „drivers“ (H-Bridge) for stepper motors. The motors consume about 2A per phase.
I am using Power Mosfets: IRFZ44N, IRF9510, IRF4905, IRF740.
My question would be:
- Do you need protection diode power Mosfets? Looking at the photo of the Mosfet (on the datasheet), the Mosfet has the built-in protection diode. But I'm not sure that is the case. Or if you want to say that ...
If anyone knows, I would be very grateful ...
thanks and greetings to all ✋
thanks for sharing 😊👍
Thank you sir from Turkmenistan
THANK YOU SOOOO MUCH THAANK YOU SOO MUCH I CAN'T DESCRIBE MY gratitude 😢❤
Great video !
Well done my friend.
Nicely explained thnks
5:54 is GOOD (y)
nice vid. thanks
Nice video, keep it up, thanks :)
Quick Question? If it's not for the effectiveness and efficiency matter, can you used any one of the three types of the Transistors in any circuit(for any devices)? Just asking what pops up in my head. Thanks to you though. You taught me many things about a Transistor just now.
So great videos thank you
