Description
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.
