Description
Advanced HEXFET
®
Power 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 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
resistance and low package cost of the TO-220 contribute
to its wide acceptance throughout the industry.
