FQA11N90C 900V N-Channel MOSFET September 2006 QFET FQA11N90C 900V N-Channel MOSFET Features • • • • • • 11A, 900V, RDS(on) = 1.1Ω @VGS = 10 V Low gate charge ( typical 60 nC) Low Crss ( typical 23pF) Fast switching 100% avalanche tested Improved dv/dt capability ® 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 o [ ... ]
