IRFW644B Datasheet | 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 switching DC/DC converter and switch mode power supplies.
