FQB11N40C: N-Channel QFET® MOSFET 400V, 10.5A, 530 mΩ

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 onstate resistance, provide superior switching performance, and withstand high energy pulse in the avalanche and commutation mode. These devices are well suited for highefficiency switched mode power supplies, active power factor correction, electronic lamp ballasts based on half bridge topology.
