Ultra Low On-Resistance
Surface Mount (IRFR1205)
Straight Lead (IRFU1205)
Fast Switching
Fully Avalanche Rated
Description
The D-PAK is designed for surface mounting using
vapor phase, infrared, or wave soldering techniques.
The straight lead version (IRFU series) is for through-
hole mounting applications. Power dissipation levels
up to 1.5 watts are possible in typical surface mount
applications.
