IRFS644B – 250V 9A N-Channel Power Mosfet – TO-220F Package
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 commutation mode. These devices are well suited for high efficiency switching DC/DC converter and switch mode power supplies. Tags, IRFI644GPBF, IRFI644, IRFI 644, IRF644B, IRFI644.
