Product Summary

The FW82443BXis a 500v n-channel mosfet. The FW82443BX N-Channel enhancement mode power field effect transistors are produced using Fairchilds proprietary, planar, DMOS technology. This advanced technology has been especially tailored to minimize on-state resistance, provides superior switching performance, and withstand high energy pulse in the avalanche and commutation mode. The device is well suited for high efficiency switch mode power supplies, power factor correction and electronic lamp ballasts based on half bridge.
