SanRex
Soft Recovery Diode Module
DSR400AA is designed
for applications requiring fast switching and soft recovery
wave shape to reduce or eliminate the need for snubber
components in the circuit. It achieves very low thermal resistance
by employing thermally conductive aluminum nitride isolation.
Features
* Fast Reverse Recovery Time
* Very Soft Recovery Characteristics
* Low Forward Voltage Drop
* Low Thermal Resistance
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
