IRF644B/IRFS644B  
250V N-Channel MOSFET  
General Description  
Features  
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.
