A P-Channel MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of MOSFET that is constructed using a p-type substrate. MOSFETs are electronic devices that are widely used as switches or amplifiers in electronic circuits.

In a P-Channel MOSFET, a thin layer of oxide is grown on the surface of the p-type substrate, and a metal gate is deposited on top of the oxide.

The gate is separated from the substrate by the oxide layer and is electrically insulated from the substrate.

The gate is used to control the flow of current between the source and the drain terminals of the MOSFET.

Advanced Power MOSFETs from APEC provide the designer with the best combination of fast switching, ruggedized device design, ultra low on-resistance and cost-effectiveness.
