What is a MOSFET

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

Metal Oxide Semiconductor Field Effect Transistor (off the top of my head). This was the first acronym I learned in college in 1988 😀

[@Wardyworlds]

Haha, I've just posted the same. It's stuck in my head too and it was about 88/89 when I learned it.

[@bignamek]

I learned about bipolar junction transistors first at my school.

[@johnwarwick4105]

Wish somebody had explained things like this when I was at college years ago, what a good way of looking at it

[@GlitchyTimes]

Explained 10 times better in less than a minute than my teacher during the whole school year on design/technology class

[@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.

[@timoooo7320]

The main reason is because mosfets can be used in Complementary circuit (CMOS) logic and do not consume energy when they're not changing states (apart from leakage current) because there is no direct path from positive to negative. BJTs do not work like that because they use current to switch, they are always consuming energy

[@geekchameleon]

Beautifully explained. Clear, concise and relatable.

[@backkslashhh]

Relatable?!

[@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

[@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.

[@muratkaradag3703]

[@carneum5128]

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

[@ajinkya3.14]

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

[@tnekkc]

I designed with mosfets from 1984 to 2008. They kept getting better

[@novtek]

This is a power transistor. Transistors come in PNP or NPN configuration depending on whether you wish to enable or block the flow of electrons. Transistors come in a variety of doped materials depending on their use. Power transistors have a heat sink on the back to pull heat away from the junction which can be a metal oxide doped silicon using a electric field to effect the flow. This means the transistor is a Metal Oxide Semiconductor Field Effect Transister (or MOSFET for short).

[@PerpetualMan22]

Used to invert signals and stores it's state when the power is off

[@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

Thank you! The most concise explanation Ive found!

[@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.)

[@linggiman]

[@isaacschmitt4803]

I love the water analogy for circuits. To the extent of my knowledge, it always works. It also helps with visualizing current and power (or voltage). In fact, yesterday, one of my technically inclined 6th grade students was looking through a book about electronics and asked me what a capacitor did exactly. The best explanation I could think to give, at least for his level, is to compare it to a bucket. Your power supply is like the water faucet; you can turn it on and off, but it will always give you water as long as there's water to give. Your bucket, on the other hand, starts off empty, but you can fill it up. If you need a lot of water somewhere quickly, you * could * turn on the tap, but that water flow is pretty slow. If you filled a bucket full of water, you could dump the whole thing at once. But capacitors can also be dangerous. You need to be careful with your full bucket, or you could dump the whole thing on you, just like if you accidentally discharge a capacitor with your fingers, you could dump the entire current through your body.

I think the constant pressure analogy is more of a BJT thing, where the base must have a constant supply of current to operate the transistor in the "on" state. While a FET is more of a wall switch, it takes power to change states but is relatively efficient when not changing.

Metal oxide semiconductor field effect transistor, Q theory or transistor theory was one of the hardest things for me to understand in Avionics training for the Navy. Transistors like a lot of electronic components can be used for different functions. A transistor can be used as a switch like in this video or it can be used to amplify an audio signal. Ever wonder why amplifiers have those big heat sinks? They are attached directly to the final output transistors to keep them cool. I’m not an engineer so my terminology may be skewed a bit.

[@UneedAname45]

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.
