If you could laser etch the casings off of some more transistors I would be interested in buying them. If you are interested in such a deal let me know and I'll give you more details as to the application.
Please contact me via the website with any business proposals. I likely won't see comments.
Hi I really liked your channel,pls can you make a video about digital potentiometer.
please can u explain what inside pc motherboard ,its cool with laser like your intro. and what connect .i cannot find anywhere .if u can try with am4 motherboard ,Thanks before😊👍
This is hands down the best and most comprehensive animated explanation about MOSFETs I've ever seen and I have seen a few
It has taken weeks and weeks of work, but it's here
Very good video, excellent 👍@@EngineeringMindset
@@EngineeringMindset Amazing level of detail and knowledge, id agree that's the best MOSFET video I've ever seen and it beats most academic explanations and teachings too !
Agreed!
I completely agree
I've been playing with electronics as a hobby for over 20 years. No one has ever explained MOSFETs this comprehensively to me before.
This made me flash back into time when i understood how BJT's worked for the first time.
Can't anyone ever think of a different comment?
If I could make a suggestion: When teaching about something like this, where there are multiple versions of the same thing, I've found that it's incredibly helpful to go through use cases for the different versions.
It's so much easier to understand and remember what something does, when you understand what problem it solves.
In any case, thank you for yet another amazingly well produced and presented video.
Thanks for the tip! I have included examples and even 2 circuits for viewers to build themselves in the video
@@EngineeringMindsetAbsolutely, and the examples do highlight what the "normal" mosfet is used for, which is great. But the example doesn't show when or why you would use the different types.
It might be outside the scope of a single video, and it's probably a ton of work to come up with a unique demonstration for each type.
It's just something that worked for me when I was learning to program. When I didn't understand why a function worked like it did, I just had to find out which problem it was designed to solve.
@@EngineeringMindset I think perhaps they were talking something more practical on why N and P type exist and why one would get used over another. Or that depletion mode mosfets are very rarely used outside fairly specific niches.
@@zyeborm Depletion mode MOSFETs are like ideal current sources in text books.
I am an independent learner. Autistic and not very good in classrooms. Your videos are amazingly helpful. Thank you for your videos that are audio-visually stimulating and engaging.
Glad to hear the content is helpful for you
Amazing video, I’m a current EE undergrad, when i took electronics, my professor didn’t seem to throughly explain MOSFETs like you did. I look forward to your uploads!
Hope it helps, enjoy
I'm a heavy pooper
It’s because of videos like these that I’m able to learn so much about engineering! Thank you ❤
Happy to help!
Great video. Just wanted to point out at 10:50 and 11:15 that p and n type materials are neutral. The p is for holes(positive) majority carriers and n is for electrons(negative) majority carriers. Then when they both diffuse(movement due to concentration gradient) in opposite type material at p-n junction, then space charge region is formed.
I did quit engineering for I.T for a lack of such explanation in my previous school. However, I'm finding this very handy as an IOT enthusiast! Good job Engineering mindset!
I'm a Mechatronics Engineer with 7yrs of experience in Machine's Service and Maintenance. Let me tell you one thing, I've never seen a video with such better explanation till date. Subscribed your channel bcz today I learnt something here that will add a good value in my life. Good Work 👍
Took the ASVAB today for Air Force, needed atleast 60 on the electrical portion of the test to go into the field I want, if I didn’t get the score I wanted i’d have to go into a different field or wait 6 months in order to retake the test. I went online to find what I could to study, I came across your channel and watched probably half your videos and watched some multiple times, with one month of studying a couple hours a day I was able to turn my original 33 score into a 67 for electrical information. Thank you, truly.
Very glad to hear
Just look at this analogy of transistors with water pipes, how adorable is that. Isn't it so easy and interesting to understand? Thanks so much man, because of you so many of us are now really understanding the concepts of electronic components and their working principle. HATS OFF Champ
This video is exactly what I've been searching for! The explanations are clear, and I appreciate how accessible it is for everyone. Thank you so much for sharing such valuable content for free! One suggestion I have is to consider slowing down the pace of the practical explanations a bit, as they can be a little quick. Keep up the great work!
Thank you, glad to hear and thank you for the donation, much appreciated.
I'm a MechE senior, when I took electronic courses for my major, they taught mostly the BJT transistor and so that is what we use in lab with our arduino and motor circuits.
The detailed explanation of MOSFETs you have here is fantastic and exactly what I would be hunting for as a student eager to learn about this subject. I feel lucky to have access to your channel, thanks for the education!
I wish I had access to my videos when I was a student!
ALL the MOSFET information your college EE professors DIDNT want you to have! And no page flipping, memorizing and referencing back and forth, and back and forth, and back and forth either!
Thank you!
It would take a feat of engineering to design a simpler explaination of Mosfets. LOL Good pacing, animation, real parts demonstration, and starting with basic switches were all fantastic.
Thanks Jeremy, glad you enjoyed!
^^^If you're not subscribed to Jeremy Fielding, he runs a great channel and he's sooo close to 1M subs. Help him out.
Perfect timing. I had just finished most interesting component on the channel and this pops up.
Please keep doing this, and make videos on every type of sensors in the future
More to come!
I saw this video 2 days ago and today I had job interview, interviewer ask me many questions related to MOSFET and luckily I had seen this video, this helped me a lot 😁😁😁
Dude... Amazing how simple (yet in a very informative way) you put things here... That's another great video... Thanks!
WOW. Hands down this is the best and most thorough explanation of MOSFETs I’ve ever witnessed. This is coming from an Electrical Engineer that has taken many classes on them. What beautiful intuitions this provides oh my word!
I love how engineering mindset always explains anything with a really great analogy. 🥰
Thats EXACTLY what Im going to study now! Thanks for this.
Excellent! Just what you need
that intro shot was absolutely beautiful
Great video! You got something wrong at 10:46 tho. The whole material is neutral as phosphorus also has 15 instead of 14 protons. The n-type refers to the negative charge carriers.
This video on MOSFET is exceptionally informative and comprehensive, providing a thorough understanding of the subject. ❤
The best electronic engineering videos on the internet!
The way you simplify and solidify the concepts is literally incredible.
And we highly appreciate it.
Keep up with the good work!
At 10:50 according to charge neutrality the overall material will be electrically neutral because we doped the material with phosphorus atom which has same number of electrons and protons hence although it has an extra electron in valance shell but it has same number of protons as well so it will be electrically neutral 😊
Generally I watch educational videos in speed multiplied. This is the first video i have ever watched in 0.75x. Even then watched it on repeat at some points. Pure content☺️
Most of the knowledge about electronics I have aquired is from your channel, which was suggested by one of my friend. Thanks a lot for your work 🥰
That PN junction explanation is perfect. Thank you
I could be good to mention the Body diode on mosfets are always there, And when you apply greater voltage on the source than drain the mosfet will always conduct no matter if the Gate is active or not. Also that the gate to source voltage is what turns the mosfet on and if you have it configured in a way that the source voltage can be different than 0 Volts such as when you have a load in the path to ground you must add up that voltage to keep the gate on otherwise the mosfet turns off again. this could happen in the reversing motor example in the video. also that you can have 2 different sources of voltages to go around this problem in example using a driver transformer for switching applications. I could talk mosfets all day
Came to the comments to see if I was the only one. This is a more thorough explanation than I normally see, so I was hoping to see those details. Never really understood why that diode is there until I saw him add that wire to the body. Would have been nice to see that covered.
@@mattn5011 yeah. This body diode in mosfets are not really added by choice but it is a part of what makes a mosfet what it is. Due to the specific doping of materials you gain this diode in one direction of the chip.
Sometimes you have avalanche rated body diodes and sometimes not.
But you can in certain types of operation use these as snubber networks too
omg thank you i finally understand mosfets (not really but at least im much less confused)
This is amazing. I'm looking at concepts I thought I'd known reasonably well for 40 years and having aha moments one after another. Really well considered explanations and great graphics. Incredible exploration of transistor operation, specifically MOSFETs. Thank you so much
This is just about the only video one needs in order to go from zero to knowledgeable on transistors. The graphic illustrations are just brilliant. Thanks so much for this!
This was an instant subscribe. Maybe the best basic (not math) descriptions for FETs I’ve seen. Great animations clear script, awesome work. Thank you!
Take care, an n-type doped material is NOT negatively charged. The Phosphor atom does have 5 electrons but it also has 5 protons, evening out the overall charge of the material.
I really appreciate it Mr. Evans!! This is exactly what I've been needing. I watched something last night on the 'HVAC School' channel where the topics covered included how technicians who truly understand a working principle are able to construct and modify a visual representation in their minds as they work, and how critical this is. Every video of yours has helped me to understand and appreciate more of the physics of electrical engineering. I have shared many of your fundamental videos with my coworkers, study partners, and even my siblings over the last couple years. You are truly teaching and inspiring confidence in a generation of technicians and engineers. I appreciate you!
Exactly
Wow, suddenly everything makes sense. I just realized that this is how the lm317 works. I had thought of it like a small magic box before. Thanks Paul :) you've helped me learn so much about each component in current controlled drivers.
Always wondered how they work, will help me when I become a licensed sparky (Electrician) and then I can take on engineering projects while having an advanced understanding on the components used
That was far and way the best description of how. MOSFET works and why I should care than I have ever seen before. Nice work.
wow you ACTUALLY explain HOW IT WORKS this is great, now i feel much more confident using this component
This is very perfect video for me. Thanks! It should be taught this way in school too!
This was most enlightening sir! Best aggregate explanation of mosfet I've read or heard. Thank you. Greetings from New Mexico!
This is the best video I've seen about mosfet!!!! Congrats
Best explanation of MOSFETs I've seen and I have done multiple electronic materials courses at university
I particularly needed and like the part about the differences in the detail of the symbols of different types of mosfets correspond to their physical construction.
This was actually one of the best explanations I have seen
Absolutely the best explanation of a MOSFET available.
I wish I had this 30 years ago. Due to poor grades, I was 'asked' to leave EE program in 1991. I would have had to repeat 3 years, plus take 2 more, or I could finish Comp Sci in 10 months. Thank you for amazing material.
After years of working with MOSFETs, this video finally gave me a more intuitive understanding of how they work! Thank you for this comprehensive and clearly presented video!
the best tutorial i have ever seen about mosfets its pretty simple now thank you for this viedo :)
Totally agree with other comments! Great job explaining them better than anyone else ever has. Covered just about every important aspect of them I originally learned in my courses in electronics in a fraction of the time and ways that are more practical to understand.
Excellent content, I'm ganna need to rewatch this a few times. But it helped alot for understanding. I rely on these videos! Thank you!
Glad it was helpful!
so amazingly simple explanation ... good work
I dont normally give thumbs up as I am lazy but this is great work. If only my tutors could have explained pinch off and saturation as well as you did. Well done !
Thank you, glad you enjoyed. If you could share with your friends, colleagues so we can help more people, that would be fantastic
It is very interesting how the architecture of the MOSFET looks like. Your video is great and highly educational! You've got a new subscriber. 👍
This is definitely very informative and very interesting. You made this so easy to follow and understand. Thank you sir.
Learning about how these work in class, and then ACTUALLY learning how they work in your channel, is so nice! I can tead technical descriptions of these all day but without a simplified explrnation and actually seeing it, i wont get it that well.
So THANK YOU for the comminity posts holighting these videos! They are too notch and i would probebly forget to check your channel for vids on them otherwise.
Pure gold. Thanks so much. Greetings from Bolivia
Glad you enjoyed it!
What an incredibly high quality video, please make more videos like this! ❤
Thanks for good explanation on how they work.
informative. direct. clear. incredible work
My electronics courses were a disaster in engineering collage time. This is heavenly
Amazing explanation, it must have taken a lot of work to put this together
I would really enjoy a video like this but about IGBTs. In certain fields, they are seen much more than MOSFETs. They're becoming increasingly popular too.
Igbt's are very common on trains , use em to control AC traction motors as they can handle the high currents used and are capable of very fast switching speeds allowing fine control over motor speed
Very good description indeed. Congratulations
I don’t think anyone could have explained to me as good as you did in this video. Until now I had a huge problem with mosfets. They always seemed way too complicated and didn’t make sense to me until now👏 Thank you so much!
Ive understandso well in this 20 min video than my 8 week class. Thank you so much. subscribed.
This is pretty good. Explained many doubts I had.
Ok, this is the best explanation of transistors i've ever seen. Much appreciated.
Hands down the best electronics videos I have ever come across in my entire life
Now the perfect understanding comes! Thanks.
Thank you so much for the wonderful explanation 😊
most well explained video i have seen in years, thanks!
amazing visuals, very understandable!! thank you
I took a degree in Engineering physics. What a delight to be refreshed in this topic by such a well created video. Thanks!
I am a student of Class 7th but quite interested in Electronic components
Keep learning and practicing. If you don't know where to start, a good way to start practicing is with an electronics kit that has a breadboard. Also make sure to have 9 volt batteries for your breadboard circuits also. Good luck young man! 👍
It will be very useful for u in Btech first year.
Huh! I have been doing it when I was 7-8 years old
I've solved various MOSFET-related problems in the school days. Then, I stumbled upon a video from Engineering Mindset, a platform I often turn to for electrical engineering insights. This video offered a comprehensive explanation of MOSFET operation, shedding light on why my Arduino Nano may have malfunctioned when attempting to regulate the speed of a DC motor during my DIY projects.
At 11:20, I think that instead of carriers migrating to the other side, the electrons and holes recombine in the depletion region and what repels more charge carriers from coming is ions in the lattice.
This is a true gem.
Finally... a perfectly explained Mosfet video!
I wish I have watched this video years ago. The information is so clear and easy to understand
And I haven't known this: 5:34 using an incorrect circuit or no resistor at all (thinking that only bjts need them)
The comparison of MOSFETs and BJTs made all the difference. Thank you!
Finally someone has explained it in a way that you can imagine. Thank you very much!
Your content is so amazing! This MOSFET video is pure gold! Thank you!
Glad you enjoy it!
Thank you for this explanation. The light bulb experiment surprised me when the bulb stayed on.
Nothing short of amazing. Thank you very much for this.
Im gonna recommend you to my Engineering Teacher! Now this is a lesson id actually want to watch
Explanation with very good illustrations
You are making a best videos for us thankyou ❤
This is the best video on MOSFETS I've ever seen!
