Description

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.

accommodating die sizes up to HEX-4. It provides the

highest power capability and the lowest possible on-

resistance in any existing surface mount package. The

low internal connection resistance and can dissipate up to

2.0W in a typical surface mount application.
