SanRex

ISOLATED DIODE MODULE (SOFT RECOVERY DIODE)

RRM

SanRex Soft Recovery Diode Module DSR300BA is designed

for applications requiring fast switching and soft recovery

wave shape to reduce or eliminate the need for snubber

components in the circuit. The modules are isolated for easy

mounting with other components or a common heatsink.

Features

* Very Fast Reverse Recovery Time

* Soft Recovery Characteristics

* Low Forward Voltage Drop

* UL registered E76102

Typical Applications

* Welding and Plasma Cutting Machines

* DC chopper

* Rectifier in Switch Mode Power Supplies (SMPS)

* Uninterruptible Power Supplies (UPS)

* Free Wheeling Diode in converters and motor control circuits
