MSCD36-12

Overview

The MSCD36-12 is a glass-passified rectifier diode module from the Microsemi MSCD36 series. It features a dual common-cathode configuration with a maximum repetitive reverse voltage of 1200V and an average forward current rating of 36A per diode under specified thermal conditions. The device utilizes an aluminum oxide DBC ceramic isolated metal baseplate for efficient heat transfer, ensuring reliable operation in high-power applications.

Feature Summary

• Dual common-cathode configuration for bridge rectification
• High blocking voltage capability up to 1800V across the series
• Heat dissipation via aluminum oxide DBC ceramic isolated metal baseplate
• Glass passivated chip construction for enhanced stability

Applications

• Non-controllable rectifiers for AC/AC converters
• Line rectifiers for transistorized AC motor controllers
• Field supply for DC motors

Procurement Notes

Verify the specific suffix against official datasheets to confirm voltage ratings, as the series spans multiple voltage classes. Confirm package type D1 compatibility during integration. Check for RoHS compliance status if required by project specifications. Ensure thermal management design aligns with the specified junction-to-case thermal resistance values provided in the electrical characteristics section.

Selection Notes

Select this module based on the required 1200V blocking voltage and 36A current handling capacity. Consider the thermal environment, as performance depends on heatsink mounting torque and case temperature limits. Evaluate surge current requirements against the 650A IFSM rating. Compare alternative series members like MSKD or MSAD if different voltage or recovery characteristics are needed.

Part Context

This component belongs to the MSCD36 family of high-voltage power discrete modules manufactured by Microsemi Corporation. The series includes variants with different voltage ratings (800V, 1200V, 1600V, 1800V) and configurations. These modules are designed for robust industrial power conversion environments requiring high reliability and efficient thermal management through their isolated baseplate design.

Replacement Considerations

Direct substitutes within the same voltage class include the MSAD36-12 and MSKD36-12. These share identical mechanical dimensions and electrical ratings but may differ in internal chip processing or packaging nuances. Verify pinout compatibility and thermal interface requirements before substitution.
