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 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.
