TM
FQB12N50 / FQI12N50
500V 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 high efficiency switch mode power supplies,
power factor correction, electronic lamp ballasts based on
half bridge.
