Overview
IRF644B — N-Channel BFET MOSFET IRF644B N-Channel BFET MOSFET 250 V, 14 A, 280 mΩ Description These N-Channel enhancement mode power field effect transistors are produced using ON Semiconductor’s proprietary, planar, DMOS technology.
This advanced technology has been especially tailored to minimize onstate 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 converters and switch mode power supplies.
Features • 14 A, 250 V, RDS(on) = 280 mΩ @ VGS = 10 V • Low gate charge (Typ.
47 nC) • Low Crss (Typ.
30 pF) • Fast Switching • 100% Avalanche Tested • Improved dv/dt Capability D GDS TO-220 G Absolute Maximum Ratings TC = 25°C unless otherwise noted.
