SanRex
ISOLATED DIODE MODULE (SOFT RECOVERY DIODE)
DKA300AA50/60 VRRM=500/600V, IFAV=150A, trr=230ns, Softness=0.8
SanRex Soft Recovery Diode Module DKA300AA 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
