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.
