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.

[@EngineeringMindset]

Please contact me via the website with any business proposals. I likely won't see comments.

[@bjornroesbeke]

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.

[@johnf817]

Can't anyone ever think of a different comment?

[@amalkrishna8732]

Hi,iam also a boy who has tried and progressing in understanding transistors.As a long time hobbyist of electronics,can you recommend us any books or how to learn the electronics and build useful complex circuits with understanding

[@whynotdean8966]

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.

[@EngineeringMindset]

Thanks for the tip! I have included examples and even 2 circuits for viewers to build themselves in the video

[@whynotdean8966]

​@@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.

[@zyeborm]

@@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.

[@alejandroperez5368]

@@zyeborm Depletion mode MOSFETs are like ideal current sources in text books.

[@sandspar]

@@whynotdean8966 ​ @whynotdean8966 Your request was simple and helpful, I also learn best the same way, by application examples. Sadly this is exactly why science remains confusing to so many; those who possess the knowledge often teach to the same perceptive syntax as themselves, as well as respond to queries in kind. AI can overcome this, but I for one am sad to see humans fall short of optimizing education first. Interaction is valuable and should be cultivated. Thanks for your suggestion.

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!

[@tushargarg1106]

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.

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.

[@debotushdas3388]

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 😊

[@terrencehairston1435]

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!

[@4udio_Vortex]

This really is how all things should be taught/explained. I've always struggled learning new concepts because they start teaching them thinking everyone has a fundamental grasp on the concepts they are teaching... but it's almost never the case. Explaining it with analogies to understand EXACTLY what this thing is doing breaks that barrier and people can carry on learning. I can't imagine the amount of brilliant minds flushed down the toilet because they needed to be taught this way so they can confidently progress forward.

[@nannesoar]

[@Omni-Qadhaya]

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.

[@Pulverrostmannen]

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

[@mattn5011]

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.

[@Pulverrostmannen]

@@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

[@felixb.1756]

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.

[@NolanHergert]

Excellent video. Keep it up!

[@EngineeringMindset]

[@bioemilianosky]

This was an inmense resource. I had knowledge on mosfets but I didnt realize that since the gate is a capacitor, it will stay activated if its not discharged. Also, your explanation made clear the usages or P and N type for normally closed and open mosfets, since depending on type you need either positive or negative voltage to activate the mosfet.

[@geoffreyworley5853]

Fantastic programme. It has restated my interest in Electronics. Brilliant clear and concise

[@shambukarijayanth7120]

10:50 Better would've been to say, 'It's n-channel because the free carriers are negatively charged.' Because, overall either n-doped or p-doped or just silicon are all neutral. When phosphorus is added, it not only brings an extra electron but also an extra proton with it. On atomic scale, there are charge imbalances because of the free carriers moving here and there but the overall structure is neutral.

[@bramfran4326]

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.
