MSRTA500120A

Overview

The MSRTA500120A is a silicon standard recovery diode array manufactured by GeneSiC Semiconductor. It features one pair of common cathode diodes housed in a heavy three-tower base-mounted package. The device supports a repetitive peak reverse voltage (VRRM) of 1200 V and a continuous forward current (IF) of 500 A. Key electrical parameters include a maximum DC blocking voltage of 1200 V, an RMS reverse voltage of 840 V, and a forward voltage of 1.2 V at 500 A. The junction-to-case thermal resistance is 0.12 °C/W, with an operating temperature range from -40°C to 175°C.

Feature Summary

• Heavy three-tower package design for robust mechanical mounting
• High surge capability supporting significant non-repetitive forward currents
• Electrically isolated base plate construction

Applications

• Industrial power conversion systems
• High-voltage rectifier circuits
• Medium to high-frequency power electronics applications

Procurement Notes

Verify the specific suffix designation against official GeneSiC documentation to confirm exact electrical tolerances and packaging variations. Ensure thermal management solutions align with the specified junction-to-case thermal resistance values. Confirm that the selected module meets the required voltage and current ratings for the target application environment before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high current handling and elevated reverse voltage capabilities within a single module. The silicon standard recovery technology offers a balance of performance and cost for general-purpose power rectification. Consider the thermal resistance and package size when designing heat sinks and PCB layouts to ensure reliable operation within the specified temperature limits.

Part Context

This part belongs to the MSRTA series of silicon power Schottky and standard recovery diodes from GeneSiC Semiconductor. The series includes variants with different voltage ratings up to 1600 V, all sharing similar current handling and packaging characteristics. These modules are designed for demanding power electronic environments where reliability and surge capacity are critical.

Replacement Considerations

Direct substitutes must match the 1200 V rating, 500 A current capacity, and three-tower package form factor. Verify compatibility with existing thermal interface materials and mounting hardware. Cross-reference datasheets for equivalent reverse leakage and forward voltage specifications to ensure circuit performance remains unchanged.
