MOSFET: Metal Oxide Semiconductor Field Effect Transistor

MOSFET means "Metal Oxide Semiconductor FET" or insulated gate FET

A special type of transistor that has a version FET NPN and one PNP.

The NPN is called N-channel MOSFET and PNP is called P-channel MOSFET

A thin layer of insulating material made of silicon dioxide (SiO2) (also called "silica" or "silica") is placed on the side of the semiconductor and a metal layer is placed on the side of the gate (GATE) (see figure)

The N-channel MOSFET the "N" is connected to the source (source) and drain (drain)
The P channel MOSFET the "P" is connected to the source (source) and drain (drain)

bipolar transistors in the current flowing through the collector is controlled by the current flowing through the base. However in the case of FET transistors, the output current is controlled by an input voltage (electric field). In this case there is no input current.

MOSFET transistors are easily damaged and must be handled with care. Because the oxide layer is very thin, can be destroyed easily if there is high voltage or static electricity.
