IRF840B Description
These N-channel enhanced power field effect transistors are produced using Fairchild's proprietary planar DMOS technology. This advanced technology is specifically tailored to minimize on-resistance, provide excellent switching performance, and withstand high-energy pulses in avalanche and rectifier modes. These devices are ideal for half-bridge-based efficient switching mode power supplies, power factor correction and electronic lamp ballasts.
