Description
These N-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.
