Fast Soft Recovery Rectifier Diode, 85 A

FEATURES

• 150 °C max. operating junction temperature

• Output rectification and freewheeling in

inverters, choppers and converters

• Input rectifications where severe restrictions

on conducted EMI should be met

• Screw mounting only

• Designed and qualified according to JEDEC-JESD47

• PowerTab® package

• Compliant to RoHS Directive 2002/95/EC

DESCRIPTION

The VS-85EPF12 fast soft recovery rectifier series has been

optimized for combined short reverse recovery time and low

forward voltage drop.

The glass passivation ensures stable reliable operation in

the most severe temperature and power cycling conditions.

Available in the new PowerTab® package, this new series is

suitable for a large range of applications combining

excellent die to footprint ratio and sturdeness connectivity

for use in high current environments.
