8EWS..S
SURFACE MOUNTABLE
INPUT RECTIFIER DIODE
Description/Features
The 8EWS..S rectifier
SAFE
IR
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.
Typical applications are in input rectification and these
products are designed to be used with International
Rectifier Switches and Output Rectifiers which are
available in identical package outlines.
