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.
The D
2
Pak is a surface mount power package capable of
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
D
2
Pak is suitable for high current applications because of its
low internal connection resistance and can dissipate up to
2.0W in a typical surface mount application.
The through-hole version (IRF640NL) is available for low-
profile application.
