Description
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.
