The 8EWF..SPbF fast soft recovery rectifier
series has been optimized for combined short
reverse recovery time, low forward voltage drop
and low leakage current.

The glass passivation ensures stable reliable operation in
the most severe temperature and power cycling conditions.

This series is designed and qualified for industrial level and
