IRFI840B
IRFI840B is 500V N-Channel MOSFET manufactured by Fairchild Semiconductor.
Description These N-Channel enhancement mode power field effect transistors are produced using Fairchild’s proprietary, planar, 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 mutation mode. These devices are well suited for high efficiency switch mode power supplies, power factor correction and electronic lamp ballasts based on half bridge.
