MCD700-12IO1W

Overview

The IXYS MCD700-12IO1W is a water-cooled thyristor/diode module with a 1200 V repetitive peak off-state voltage (VDRM) and reverse voltage (VRRM). It provides a nominal RMS on-state current of 700 A at 42°C inlet water temperature. The device features a critical rate of rise of on-state current (di/dt) of 300 A/µs non-repetitive and 150 A/µs repetitive. Peak surge current reaches 16.5 kA for a 10 ms half-sine wave. Thermal resistance from junction to water is 0.09 K/W. Operating temperature ranges from -40°C to +125°C, with an isolation voltage of 3500 V AC RMS.

Feature Summary

• Integrated anti-parallel diode configuration within a single water-cooled package
• High thermal conductivity base designed for direct liquid cooling applications
• Robust gate drive requirements ensuring reliable turn-on under high di/dt conditions

Applications

• Industrial motor drives and variable frequency drives
• High-power DC power supplies and rectifiers
• HVDC transmission and static VAR compensators

Procurement Notes

Verify the specific ordering code against the manufacturer's latest documentation before purchase. Confirm that the procurement channel is authorized by IXYS or Westcode Semiconductors. Ensure the component matches the exact suffix specifications required for your application. Request original datasheets to validate technical parameters upon delivery.

Selection Notes

Select this module based on the 1200 V blocking capability and 700 A continuous current rating. Evaluate the thermal management system to maintain the specified inlet water temperature for optimal current derating. Ensure the gate drive circuit can supply the necessary trigger current and voltage levels. Verify that the mechanical mounting forces align with the specified torque requirements for the heatsink interface.

Part Context

This component belongs to the IXYS M##700 series of high-current thyristor modules. The 'C' designation indicates a thyristor/diode configuration. The '12' specifies the 1200 V voltage grade. The 'io1W' suffix denotes a critical dv/dt rating of 1000 V/µs and a water-cooled base. This series is engineered for heavy-duty industrial power conversion systems requiring high reliability.

Replacement Considerations

Direct replacements must match the 1200 V rating, 700 A current capacity, and water-cooled mounting style. Verify compatibility with existing cooling channels and electrical interfaces. Cross-reference with other IXYS Westcode modules in the same family if available. Consult the manufacturer for updated alternatives if the part is discontinued.
