International Rectifier's Fifth Generation HEXFETs use innovative processing techniques to provide the lowest on-resistance per silicon area.
This advantage, along with HEXFET Power MOSFETs' well-known fast switching speed and ruggedized device design, gives the designer a highly effective device that may be used in a wide range of applications.
For all commercial-industrial applications with power dissipation levels up to about 50 watts, the TO-220 package is universally recommended.
The TO-220 is widely accepted in the industry, due in part to its low package cost and low heat resistance.
