Procurement Notes

Verify the specific ordering suffix against official datasheets to confirm pinout and terminal configuration compatibility. Confirm RoHS compliance status through manufacturer documentation prior to integration. Ensure cooling system specifications match the module's thermal requirements for optimal reliability and lifespan during operation.

Selection Notes

Select this component when designing systems requiring 700 A continuous current handling with 1.6 kV blocking capability. The water-cooled WC-500 package necessitates compatible cooling infrastructure. Evaluate thermal resistance parameters against system heat sink designs to maintain junction temperatures within the specified operational limits for long-term stability.

Part Context

This module belongs to IXYS' discrete semiconductor module portfolio, specifically targeting high-power thyristor applications. It complements other MCMA and MDMA series components by offering specialized water-cooled solutions for currents exceeding standard air-cooled limits, serving niche industrial power electronics markets.

Replacement Considerations

Check for direct cross-references from manufacturers like Semikron or Mitsubishi Electric. Verify that alternative modules match the 700 A current rating, 1.6 kV voltage class, and WC-500 mechanical footprint to ensure interchangeability without redesigning the cooling assembly.
