These P-Channel MOSFETs 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 battery and
load management.
A thermally enhanced large pad leadframe has been
incorporated into the standard SOT-23 package to produce a
HEXFET Power MOSFET with the industry's smallest footprint.
This package, dubbed the Micro3, is ideal for applications
where printed circuit board space is at a premium. The low
profile (<1.1mm) of the Micro3 allows it to fit easily into
extremely thin application environments such as portable
electronics and PCMCIA cards. The thermal resistance and
power dissipation are the best available.
