FQPF12N60CT 600V N-Channel MOSFET is a power field effect transistor produced by Fairchild Semiconductor Corporation using Fairchild's proprietary planar stripe DMOS technology. This advanced technology has been specially 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.
