• Repetitive avalanche rated

• Fast switching

• Ease of paralleling

• Simple drive requirements

• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912

Note

*

Thi s datasheet pro vi des information about parts that are
RoHS-compliant and / or parts that are non-RoHS-compliant. For
example, parts with lead (Pb) terminations are not RoHS-compliant.
Please see the information / tables in this datasheet for details.

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-220AB 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-220AB contribute to its
wide acceptance throughout the industry.
