Fifth Generation HEXFETs from International Rectifier utilize advanced processing
techniques to achieve the lowest possible 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 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.
