S
N-Channel MOSFET
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 4 pin DIP package is a low cost machine-insertable
case style which can be stacked in multiple combinations on
standard 0.1 inch pin centers. The dual drain serves as a
thermal link to the mounting surface for power dissipation
levels up to 1 W.
