Description
These N-Channel HEXFET® power MOSFETs from
International Rectifier utilize advanced processing
techniques to achieve the extremely low on-resistance
per silicon area. This benefit provides the designer
with an extremely efficient device for use in battery
and load management 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, infrared, or wave soldering techniques.
