DESCRIPTION
The VS-8EWS..S-M3 rectifier high voltage series has been
optimized for very low forward voltage drop, with moderate
leakage. The glass passivation technology used has reliable
operation up to 150 °C junction temperature.
The
high reverse voltage
range available allows design of
input stage primary rectification with
outstanding voltage
surge
capability.
