FQD18N20V2 / FQU18N20V2
200V N-Channel MOSFET
General Description
Features
These N-Channel enhancement mode power field effect
transistors are produced using Fairchild’s proprietary,
planar stripe, DMOS technology.
This advanced technology has been especially tailored to
minimize on-state resistance, provide superior switching
performance, and withstand high energy pulse in the
avalanche and commutation mode. These devices are well
suited for low voltage applications such as automotive, high
efficiency switching for DC/DC converters, and DC motor
control.
