FEATURES

• Dynamic dV/dt Rating

• Repetitive Avalanche Rated

• Fast Switching

• Ease of Paralleling

• Simple Drive Requirements

• Lead (Pb)-free

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.
