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.
A customized 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.
