85EPF12 Soft Recovery Series

Vishay High Power Products

FEATURES

• Output rectification and freewheeling in
inverters, choppers and converters

• Input rectifications where severe restrictions
on conducted EMI should be met

• Compliant to RoHS directive 2002/95/EC

• Designed and qualified for industrial level

DESCRIPTION

The 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
is suitable for a large range of applications combining
excellent die to footprint ratio and sturdeness connectivity
for use in high current environments.
