FQA19N20C QFET FQA19N20C 200V N-Channel MOSFET 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 efficiency switched mode power supplies, active power factor correction, electronic lamp ballasts based on half bridge topology. ® Features • • • • • • 21.8A, 200V, RDS(on) = 0.17Ω @VGS = 10 V Low gate charge ( typical 40.5 nC) Low Crss ( typical 85 pF) Fast switching 100% avalanche tested Improved dv/dt capabilit [ ... ]
