Description
I
Fifth Generation HEXFETs from International Rectifier utilize
advanced processing techniques to achieve the lowest possible
on-resistance per silicon area. This benefit, combined with the
fast switching speed and ruggedized device design that HEXFET
Power MOSFETs are well known for, provides the designer with
an extremely efficient device for use in a wide variety of
applications.
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.
