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 TO-220 package is universally preferred for all

commercial-industrial applications at power dissipation
levels to approximately 50 watts. The low thermal TO-220AB
resistance and low package cost of the TO-220
contribute to its wide acceptance throughout the
industry.
