Overview
The SanRex FRD100CA120 is a high-speed fast recovery dual diode module designed for high power switching applications. It features an isolated mounting construction and high surge capability. Key electrical ratings include a repetitive peak reverse voltage of 1200 V, a DC reverse voltage of 960 V, and a continuous forward current of 100 A per device at a case temperature of 78°C. The maximum reverse recovery time is 300 ns, with a typical forward voltage drop of 1.8 V at 100 A. The junction-to-case thermal impedance is 0.4 °C/W, and the operating junction temperature range spans from -40°C to +150°C.
Feature Summary
- High speed operation with a maximum reverse recovery time of 300 ns
- Isolated mounting construction for enhanced safety and heat dissipation
- High surge capability supporting up to 2000 A non-repetitive surge current
Applications
- Switching Power Supplies
- Inverter Welding Power Supplies
- Power Supply for Telecommunication
Procurement Notes
Verify the specific part number suffix against official documentation to confirm voltage rating (100V vs 120V) and package variations. Confirm RoHS compliance status as indicated in manufacturer specifications. Ensure thermal management solutions align with the specified junction-to-case thermal impedance and maximum operating temperatures. Validate isolation breakdown voltage requirements for the intended application environment.
Selection Notes
Select this component for applications requiring high-frequency switching with low loss characteristics. Consider the 100 A continuous current rating per device when designing parallel configurations or ensuring adequate cooling. Evaluate the 1200 V reverse voltage rating against system peak voltages. Assess the need for high surge tolerance during startup or fault conditions.
Part Context
The FRD100CA120 belongs to the FRD series of Fast Recovery Diodes manufactured by SanRex Corporation. This series is engineered for robust performance in demanding power electronics environments. The module integrates two diodes in a single package, facilitating compact circuit designs while maintaining high reliability and efficiency in high-power conversion systems.
Replacement Considerations
Consult official SanRex documentation for verified substitute part numbers within the FRD series or equivalent high-speed diode modules from other manufacturers. Ensure replacement components match critical parameters such as reverse voltage, forward current, and recovery time.
