What is a MOSFET

[@mattakudesu]

Very concise and easily understood information

[@ostlandr]

This is why the Brits called vacuum tubes "valves", because that's how they work.

[@moisesnicolasabanto2351]

Ojalá pronto se pueda escuchar en español, es interesante , muchas gracias por la explicación

Ditto, thanks.

[@infegfx]

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.

[@chancylvania]

As is the answer in most of electronics: just read the data sheet it’ll tell you how it works (most of the time)

best explanation of what a mosfet is ever and been watching electronic videos for a decade now

[@mfr04]

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]

So you mean once its on and voltage is removed it will keep on?

[@mfr04]

@@August301989 That's right, the mosfet will remain on until the gate capacitance is discharged

[@August301989]

@@mfr04 so a static charge from my finger can turn it on. How you can prevent that?

[@mfr04]

@@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.

[@unrealcrafter2671]

Yeah I was thinking of saying that. Without a pull down a fet can stay active

I LOVE this channel. Thank you!

[@Mulakulu]

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

[@WerewolfMaster]

2 variants each of 2 types

[@Mulakulu]

@@WerewolfMaster type and variant are synonyms. We agree though. 2x2=4

[@gordonwelcher9598]

There are also dual gate mosfets.

[@Mulakulu]

@@gordonwelcher9598 I guess I set an arbitrary limit of "the most important types to know about", but sure

[@gordonwelcher9598]

@@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.

[@geekchameleon]

Beautifully explained. Clear, concise and relatable.

[@matthosseini4194]

The best explanation ever 👏👏

[@azhuransmx126]

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.

[@dylangergutierrez]

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.

[@e-to-the-power-x]

That pn junction animation was all I needed. Very clear to understand. Thank you so much!

[@carneum5128]

but idk why i cant understand its like a switch for on off may be bro?😢

[@e-to-the-power-x]

@carneum5128 it's like an electronic switch. You control it by supplying a small current

MOSFET stands for metal oxide semiconductor field effect transistor.

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. ❤

[@TIRTHKANDOI]

Very good video sir I like to see more video like this 😃.

[@webkar]

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)

[@Graham_Wideman]

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.)

[@szymonh8772]

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

[@alexgo1034]

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

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.

[@twickersruss]

Excellent explanation!

[@davidperry4013]

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.

[@davehudl3593]

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.

[@ObiWanBillKenobi]

Is it accurate to say that a MOSFET is essentially a switchable diode?

[@Pelican_t]

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.

[@kjward1975]

Love your vids

[@Qui-9]

One thing i cant wrap my head around, is how a field-effect can be generated on a channel through an insulator. I'd think that channel would immediately drain any charge induced on it, and the only field left would be within the insulator only?

[@EngineeringMindset]

See the full tutorial, link bottom left

[@jannehokkanen8175]

Well yeah, but no. There is nothing like spring to get Mosfet to off state. It is exactly the opposite. If the gate is charged, it will stay open until something will discharge it. And other thing, spring needs force to push it open. But Mosfet's gate does not need current to open, unless very high speed is required.

[@EngineeringMindset]

Yep, this is just an analogy for visual purposes. See the full video (link bottom left) for the atomic level animation along with worked examples
