SanRex
Soft Recovery Diode Module
DCA150AA
series
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
Isolated TO-240 Package
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
