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.
