3

Anode

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 and lead (Pb)-free.
