IRFP450B   Description

  These N-channel enhanced mode power field effect transistors IRFP450B are produced using Fairchild's proprietary planar DMOS technology.

This advanced technology is tailor-made to minimize on-resistance, provides superior switching performance, and withstands high-energy pulses in avalanche and rectifier modes. These devices are very suitable for high frequency switching power supplies, power factor correction and half-bridge-based electronic lamp ballasts.
