Description
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.
The SOT-223 package is designed for surface-mount
using vapor phase, infra red, or wave soldering techniques.
Its unique package design allows for easy automatic pickand-place as with other SOT or SOIC packages but has
the added advantage of improved thermal performance
due to an enlarged tab for heatsinking. Power dissipation
of 1.0W is possible in a typical surface mount application
