This datasheet is subject to change without notice.

Power MOSFET

IRF634, SiHF634

Vishay Siliconix

FEATURES

• Dynamic dV/dt Rating

• Repetitive Avalanche Rated

•Fast Switching

• Ease of Paralleling

• Simple Drive Requirements

• Compliant to RoHS Directive 2002/95/EC

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.

Notes

a. Repetitive rating; pulse width limited by maximum junction temperature (see fig. 11).

d. 1.6 mm from case.
