MOSFET stands for Metal Oxide Silicon Field Effect Transistor or Metal Oxide Semiconductor Field Effect Transistor. This is also called as IGFET meaning Insulated Gate Field Effect Transistor. The FET is operated in both depletion and enhancement modes of operation.

What are MOSFETs used for?
The MOSFET (Metal Oxide Semiconductor Field Effect Transistor) transistor is a semiconductor device that is widely used for switching purposes and for the amplification of electronic signals in electronic devices.

How do MOSFETs work?
In general, the MOSFET works as a switch, the MOSFET controls the voltage and current flow between the source and drain. The working of the MOSFET depends on the MOS capacitor, which is the semiconductor surface below the oxide layers between the source and drain terminal.

Are all MOSFETs the same?
All MOSFETs are FETs, not all FETs are MOSFETs. But the term is so common that things that are not actually MOSFETs are still called "MOSFETs", so there isn't really much difference; the terms are kind of interchangeable.

What are the types of MOSFETs?
There are two classes of MOSFETs. There is depletion mode and there is enhancement mode. Each class is available as n- or a p-channel, giving a total of four types of MOSFETs. Depletion mode comes in an N or a P and an enhancement mode comes in an N or a P.

Why N channel is better than P channel Mosfet?
The N-channel MOSFET has several advantages over the P-channel MOSFET. For example, the N-channel majority carriers (electrons) have a higher mobility than the P-channel majority carriers (holes). Because of this, the N-channel transistor has lower RDS(on) and gate capacitance for the same die area.

Is N channel NPN or PNP?
An N-Channel mosfet needs a positive Gate - Source voltage to conduct. An P-Channel mosfet needs a negative Gate - Source voltage to conduct. An NPN transistor needs a positive Base - Emitter current to conduct. An PNP transistor needs a negative Base - Emitter current to conduct.

Is 2N7000 NPN or PNP?
2N7000 is a N-channel mosfet. NPN or PNP indicated BJT type transistor. unlike BJTs mosfets are symmetrical devices and S and D is actually defined by connection of the bulk. in case of 3-pin packaged mosfets, you no longer have control of how the bulk is connected so make sure to verify pinout using correct datasheet.
