MOS FET (Metal Oxide Semiconductor Field Effect Transistor) Components (Auto) MOS

MOS FET (Metal Oxide Semiconductor Field Effect Transistor)

Components (Auto)

MOS FET (Metal

Oxide Semiconductor Field Effect Transistor) is composed of Metal, Oxide and Semiconductor.
There are NPN type and PNP type as the semiconductor part. NPN type is called N-channel and PNP type is called P channel. An oxide film is put to the semiconductor of NPN or PNP and metal is put onto it as the gate.
Transistor controls an output current by the input current. However, in case of FET, it controls an output current by input voltage.
To handle an MOS FET, it needs an attention. Because the oxidation insulation film is thin, this film is easy to destroy in the high voltage of the static electricity and so on.

MOS FET (Metal Oxide Semiconductor Field Effect Transistor)

Components (Auto)

[N-channel MOS FET]

When

positive voltage is applied to the gate of the N-channel MOS FET, the electrons of N-channel of source and drain are attracted to the gate and go into the P-channel semiconductor among both. With the move of these electrons, it becomes the condition like spans a bridge for electrons between drain and source. The size of this bridge is controlled by the voltage to apply to the gate.
