IRF644B/IRFS644B
250V N-Channel MOSFET
General 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 commutation mode. These devices are well
suited for high efficiency switching DC/DC converter and
switch mode power supplies.
Features
• 14A, 250V, RDS(on) = 0.28@VGS = 10 V
• Low gate charge ( typical 47 nC)
• Low Crss ( typical 30 pF)
• Fast switching
• 100% avalanche tested
• Improved dv/dt capability
