Procurement Notes

Verify the specific suffix code against official documentation to confirm exact voltage ratings and pin configurations. Confirm mechanical mounting torque specifications for M6 mount, M8 main terminals, and M4 control terminals prior to assembly. Ensure thermal interface materials are compatible with the specified junction-to-case thermal resistance values.

Selection Notes

Select this module for applications requiring high current capacity and robust surge handling. Consider the 1600 V rating for medium-voltage power systems. Evaluate thermal management requirements based on the 0.085 °C/W junction-to-case thermal impedance. Verify that gate trigger parameters align with the driving circuit capabilities.
