No it is not. It is for Ultimate PROs can understand as he said. It means if you have no idea about electronics like a PRO you, you can not understand.
Correction, there are 4 types of mosfets. You even mentioned them in the video, but for some reason you said there were only 2. Enhancement and depletion just says if they are normally open or normally closed, while n-channel and p-channel tells you if they are activated by a positive or negative voltage compared to the source pin
@@Mulakulu You are right. Dual gate mosfets were popular in the 70s for mixers, RF and IF amplifiers. They are not used much anymore. The second gate was used to control the gain or to inject the local oscillator. A very easy to use part similar to a tetrode or pentode vacuum tube.
The disc in the pipe analogy should not have a spring because the gate on the MOSFET acts like a capacitor. Circuit designers usually add springs using pull down or pull up resistors.
@@August301989 Yes it can. The way to prevent this is to use a high resistance resistor (usually 10k or close) connected to the gate and source. It is called a pull up resistor on a p-channel MOSFET, or a pull down resistor on an N-channel MOSFET.
MOSFETs are more efficient than other types of transistors and 10 to 60 times faster than them. Also, it can be miniaturized better to put in a chip. But they are also more delicate to electromagnetic pulses and electrostatic discharges. Even so, we made our civilization to work around this delicate technology because there are no better options, they represent now 70% of semiconductor's market.
Incorrect; MOSFETs are not fundamentally faster than other sorts of transistors. Bipolar junction transistors (BJTs) and HEMTs both have higher fundamental frequencies than FETs. You're right about extreme miniaturization though; it's much easier to make a bunch of small MOSFETs than BJTs, and due to their lack of DC gate conduction, they're better for tasks like memory and processing.
The spring in the water analogy diagram seems worng. If you remove the voltage, the channel will remain open as it's controlled by charge which will stay in the gate until you remove it (eg. by shorting to the source pin)
Incorrect. The signal you apply to the gate is a voltage. The upstream circuit does not apply and remove a voltage. It applies a positive voltage to turn on the Source-Drain path, and applies a different voltage, zero volts, to turn it off. (Assuming an N-Channel enhancement mode MOSFET example.)
I've known of, and used occasionally, MOSFETS but honestly this was the first time this was explained extremely well and concisely the two (main) types of MOSFET you'll encounter. ❤
Thank you very much. Your explanation and demonstration of both real life and illustration are very helpful. This channel is a blessed for electronic learners.😃
Best analog for mosfet is ball valve U apply voltage to the gate and let the gate alone -it remains open until u not discharge the gate No spring effect U need to discharge gate to 0
I spent countless hours at Fairchild Semi back in the 70's and 80's learning how these things worked. here's a video short explaining it all in a few minutes.
For fucks sake why can't schools be as informative. It's my 3rd year in an electronics-based highschool (best in town) and the teachers cannot explain stuff like this in 45 minutes while you do it in under a minute

I’m in a class for how to design and manufacture these chips and the short clip of the p-type region is a very helpful visualization. You should do a video on fermi levels!
Mosfet has been around for sometime and very common in computers and other electronic devices. If computer is malfunctioning, mosfet could be the culprit but not always.
Dont just check the datasheet. Live by the datasheet! They usually have sample designs and use-cases, some even tell you how to adapt their examples to your needs
This is just like a plot operated valve in hydraulics. We call it normally open (N/O) for valves for flow when pressure applied and normally closed (N/C) for closed in the rest position. That is a lot easier than what they come up with.
In a class AB amplifier there is 1 PNP and 1 NPN mosfet for each output channel for 45 to 85 watts per channel as well as capacitors and resistor to eliminate noise. For higher wattages the number of output mosfets are doubled, tripled, or more.
NPN & PNP refer to bipolar transistors and are current amplifiers, MOSFETs are P channel or N channel and amplify voltage. Pardon me for saying.😮 Also when these things are paralleled together each device is in series with a milliohms value, current sharing resistor to prevent any one device from doing all the work.
electronics would make an excellent video game. solving puzzles, building diagrams, turning on your creation for the first time, putting it to use, salvaging components, trading them with a working game economy. these all have very similar attributes to game mechanics that already exist. a mixture of electronics and and coding with an explorable online world that you can gather materials, mine, trade, sell, destroy, could create a perfect game for a nerd and young gamers can learn with possibility's of spilling out into the real world.
I think you are talking about a Thyristor. Since MOSFETs come with a body diode so if you connect it in reverse, current will flow through the body diode instead.

Very concise and easily understood information
This is why the Brits called vacuum tubes "valves", because that's how they work.
Ojalá pronto se pueda escuchar en español, es interesante , muchas gracias por la explicación
Ditto, thanks.
No it is not. It is for Ultimate PROs can understand as he said. It means if you have no idea about electronics like a PRO you, you can not understand.
As is the answer in most of electronics: just read the data sheet it’ll tell you how it works (most of the time)
Unless it only exist in chinese and you didn't learned chinese, then good luck

Metal Oxide Semiconductor Field Effect Transistor (off the top of my head). This was the first acronym I learned in college in 1988 😀
Haha, I've just posted the same. It's stuck in my head too and it was about 88/89 when I learned it.
one month strong here
Thanks :-)
Thanks for that.
I learned about bipolar junction transistors first at my school.

2 variants each of 2 types
@@WerewolfMaster type and variant are synonyms. We agree though. 2x2=4
There are also dual gate mosfets.
@@gordonwelcher9598 I guess I set an arbitrary limit of "the most important types to know about", but sure

best explanation of what a mosfet is ever and been watching electronic videos for a decade now
I LOVE this channel. Thank you!

The disc in the pipe analogy should not have a spring because the gate on the MOSFET acts like a capacitor. Circuit designers usually add springs using pull down or pull up resistors.
So you mean once its on and voltage is removed it will keep on?
@@August301989 That's right, the mosfet will remain on until the gate capacitance is discharged
@@mfr04 so a static charge from my finger can turn it on. How you can prevent that?
@@August301989 Yes it can.
The way to prevent this is to use a high resistance resistor (usually 10k or close) connected to the gate and source.
It is called a pull up resistor on a p-channel MOSFET, or a pull down resistor on an N-channel MOSFET.
Yeah I was thinking of saying that. Without a pull down a fet can stay active

@carneum5128 it's like an electronic switch. You control it by supplying a small current
It's like a digital relay.
solid state relays?

Fantastic animation. Makes it simple to understand. Thank you for your hard work. ❤
Best analogy of a Mosfet ever. Thanks smart dude
Best analog for mosfet is ball valve
U apply voltage to the gate and let the gate alone -it remains open until u not discharge the gate
No spring effect
U need to discharge gate to 0
Best illustration ive seen so far
Simple and elegant!
A fair substitute for thermic vacuum tubes in guitar amplifiers.
Thanks for that information about the types of the mosfet 😊
❤❤best explanation ever
This is my favorite way I’ve seen transistors described tysm
perfectly illustrated and explained.
You make it so easy to grasp, better than my teacher at college 😅 👍🏼

I love informational TH-cam shorts.❤
Well made and very informative. Wish I could have given it 2 thumbs up. Bravo! Do you have any vids on vacuum tubes (valves)?
Thank you for clear explanation ❤
Insightful and concsied
So basically, it's a big transistor that handles more current.
It's a type of transistor, but it works differently. Sell the full tutorial for worked example, link bottom left

Learned about mosfets when I started airsoft/gelsoft
that is good video with good visualazitaion
Beautifully explained
Wow, thank you for the simplicity of the MOSFET
Thank you for helping me learn anything I can that’s relevant to what I’m trying to invent.
This is explained super good. The sound could be better though!

And N-type enhancement are by far the most common type used by hobbyists.
Im going to take a whole ass class just to understand the drawing. Lol
Taught better than past professors 🙈
Okay. That's Depletion vs. Enhancement Types, also P- vs. N- Channel MOSFETs explained in a *very concise* way. I can memorize that!
Covered in the full tutorial, please see link bottom left or check out out main videos
They need to make them so you can test them without removing them especially in solar inverters
Very Good informative
Audio is a quite quiet compared to other videos, make sure to check your audio levels.
I am like to see more from this channel... 💥
Very cool information, thanks 👍
Mosfet has been around for sometime and very common in computers and other electronic devices. If computer is malfunctioning, mosfet could be the culprit but not always.
And that's how we make a logic circuit, and a CPU uses billions and billions of them
Best explanation ever?
Excellent!
Valve example of a mosfet is t spring loaded, you need to add the “spring” by adding a pull down resistor since it have gate charge
❤❤❤❤❤❤❤😘😘😘😘 lovely explanation

Can you please a short like this about elecrical relays?
I’ve got confused exactly half second before he said you can’t get confused 🤦🏻♂️😩😂😂😂😅
"Check the datasheet"
I don't know who's not checking the datasheet but they must be a genius.
If I were to watch this clip, I would not be failed of electron theory at University school.
Crazy how some of these things work. And yet unfortunately radioshack is gone so we can no longer buy small electronics for playing around on a whim
Very helpful
First read this on Pioneer HU's of the '90s 😊
Some1 like this in like 5 months when my nanotechnology module starts, i saw my older sis studying bout this and this vid would really help
WAIT
He realy lasered all of the plastic perfectly away to show us the inside? That's crazy genius but still over the top for such a video.
MOSFET
metal-oxide-semiconductor field-effect transistor.
These can protect control circuits in industry and home
Nice
Depletion mode FETs can be very useful, but are hard to find.

Love me them rectangular discs.
Is it accurate to say that a MOSFET is essentially a switchable diode?
I think you are talking about a Thyristor. Since MOSFETs come with a body diode so if you connect it in reverse, current will flow through the body diode instead.
Yeah check the DATA sheet, it's too late when you "let the smoke out"!
Also put a video about J-FET please
It looks like an AND gate.
They are both enhancement mosfets. changing voltage on the gate does not change the type of MOSFET.
See the full video, link bottom left, this is just a short, limited to 60 seconds by youtube
Good explanation.We are professional diode factory.
