power MOSFET - technical definition
A type of metal oxide semiconductor field effect transistor (MOSFET) used to switch large amounts of current. Power MOSFETs use a vertical structure with source and drain terminals at opposite sides of the chip. The vertical orientation eliminates crowding at the gate and offers larger channel widths. In addition, thousands of these transistor "cells" are combined into one in order to handle the high currents and voltage required of such devices.
Power MOSFETs
All power MOSFETs use a vertical structure in which the source and drain are at opposite sides of the chip. The last example is a combination of MOSFET and bipolar technologies, which is typically used in higher power applications.
