Fifth generation Power MOSFETs from Vishay 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
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 W. 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
2.0 W in a typical surface mount application.
