Input Rectifier Diode, 20 A
20ETS...S High Voltage Series
Vishay High Power Products
DESCRIPTION/FEATURES
The 20ETS...S 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.
Typical applications are in input rectification and these
products are designed to be used with Vishay HPP switches
and output rectifiers which are available in identical package
outlines.
This product series has been designed and qualified for
industrial level.
