Thermal Resistance
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.
