MSCD70-12

Overview

The MSCD70-12 is a glass-passivated rectifier diode module with a maximum repetitive reverse voltage of 1200V. It provides an average forward current rating of 70A at a case temperature of 102°C and supports a non-repetitive peak surge current of 1400A for 10ms pulses. The device features a thermal resistance from junction to case of 0.51°C/W per diode and includes 3000Vrms isolation capability between terminals and the baseplate.

Feature Summary

Utilizes glass passivation for chip protection
Features heat transfer through an aluminum oxide DBC ceramic isolated metal baseplate

Applications

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

Procurement Notes

Verify that the specific part number matches the required voltage class, as the series spans multiple ratings. Confirm compliance requirements against the datasheet specifications. Ensure mounting torque values are strictly adhered to during installation to maintain thermal performance and mechanical integrity. Review isolation voltage parameters for system safety compliance.

Selection Notes

Select this component based on the 1200V blocking voltage requirement and 70A continuous current capacity. Evaluate thermal management needs using the specified junction-to-case thermal resistance. Consider the physical dimensions and screw mounting style for integration into the target power electronics assembly.

Part Context

This module belongs to the MSKD70, MSAD70, and MSCD70 family of glass-passivated rectifier diodes. These components are designed for high-power applications requiring robust reverse blocking capabilities and efficient thermal dissipation through an isolated metal baseplate structure.
