The 20ETF..SPbF 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.

This product series has been designed and
qualified for industrial level.

Compliant to RoHS directive 2002/95/EC.

Halogen-free according to IEC 61249-2-21 definition.
