Description
Fifth Generation HEXFETs from International Rectifier
utilize advanced processing techniques to achieve
extremely low 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 and reliable device for use
in a wide variety of applications.

The SO-8 has been modified through a customized
leadframe for enhanced thermal characteristics and
multiple-die capability making it ideal in a variety of
power applications. With these improvements,
multiple devices can be used in an application with
dramatically reduced board space. The package is
designed for vapor phase, infra red, or wave soldering
techniques.
