Direct copper bonded Al2O3-ceramic base plate
Planar passivated chips
Keyed gate/cathode twin pins

Applications

Motor control
Power converter
Heat and temperature control for industrial furnaces and chemical processes
Lighting control
Contactless switches

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact voltage rating and configuration. Confirm compliance with RoHS directives and UL registration status E 72873 during sourcing. Ensure mounting hardware meets the specified torque requirements for terminal connections and module securing.

Selection Notes

Select this component based on the required 1800 V blocking capability and 450 A RMS current handling. Evaluate the thermal management requirements using the provided transient thermal impedance curves. Ensure the application circuit can accommodate the specified gate trigger characteristics and di/dt ratings for reliable operation.

Part Context

This module belongs to the MCC/MCD 250 series from IXYS, designed for high-power thyristor applications. The series offers various voltage ratings ranging from 800 V to 1800 V. The MCD variant specifically integrates a thyristor and a diode in a single package, suitable for three-phase rectifier bridges or AC controllers.

Replacement Considerations

No official substitutes are listed in the datasheet. When considering alternatives, verify matching RMS current ratings, voltage blocking capabilities, and physical dimensions. Ensure the replacement device supports similar thermal resistance values and mounting configurations.
