FQA18N50V2
500V N-Channel MOSFET
QFET TM
General Description
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 efficient switched mode power supplies,
active power factor correction, electronic lamp ballast
based on half bridge topology.
Features
• 20A, 500V, RDS(on) = 0.265@VGS = 10 V
• Low gate charge ( typical 42 nC)
• Low Crss ( typical 11 pF)
• Fast switching
• 100% avalanche tested
• Improved dv/dt capability
