N-Channel MOSFET
DESCRIPTION
Third generation Power MOSFETs from Vishay provide the
designer with the best combination of fast switching,
ruggedized device design, low on-resistance and
cost-effectiveness.
The D
2
PAK is a surface mount power package capable of
accommodating die size 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.
