Advanced HEXFET
®
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 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.
