| SanRex ISOLATED DIODE MODULE (SOFT RECOVERY DIODE) DSR300BA50/60 VRRM=500/600V, IFAV=300A, trr=250ns, Softness=0.8 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 < Maximum Ratings > Symbol Item VRRM VR(DC) Symbol IF(AV) IFSM I2t Tj Tstg V ISO Repetitive Peak Reverse Voltage Reverse D.C.
