Procurement Notes

Verify the specific suffix 'MI' against official IXYS documentation to confirm any distinct manufacturing or testing variations compared to standard variants. Ensure thermal interface material compatibility with the TO-240AA base plate for optimal heat dissipation. Confirm that the gate drive circuitry meets the specified 200mA trigger current requirement for reliable turn-on under all operating conditions.

Selection Notes

Select this component when an 1800V blocking voltage and 200A continuous current are required in a compact TO-240AA form factor. Consider the 1.75V peak on-state voltage for conduction loss calculations. Evaluate the 3.6kA surge rating against potential inrush currents in the target application to ensure adequate safety margins during startup or fault conditions.

Part Context

This part belongs to the IXYS MCMA series of silicon-controlled rectifier modules. The series is characterized by planar passivated chips and standardized mechanical dimensions. These modules are engineered for reliability in demanding power electronics environments, offering a balance of high current density and voltage blocking capability within a widely adopted industry package.

Replacement Considerations

Direct replacements must match the 1800V/200A rating and TO-240AA package. Verify pinout compatibility and thermal resistance characteristics. Cross-reference with other manufacturers' equivalent SCR modules ensuring identical electrical specifications and mechanical constraints for seamless substitution.
