Procurement Notes

Verify component authenticity by cross-referencing the Data Matrix barcode on the module label against official Infineon records. Ensure the ordering suffix matches the specific package variant required. Confirm that the application environment meets the specified insulation coordination and thermal management requirements outlined in the datasheet before finalizing procurement.

Selection Notes

Select this module for applications requiring high voltage blocking capabilities up to 4500 V and significant current handling. Consider the thermal resistance values and the necessity of an AlSiC base plate for environments demanding high thermal cycling endurance. Verify gate drive compatibility with the specified internal gate resistor and switching energy losses at the target operating frequency.

Part Context

This component belongs to the XHP™3 product family, representing advanced high-power IGBT modules. It utilizes Trench/Fieldstop IGBT4 technology to optimize switching performance and conduction losses. The series is engineered for industrial and traction applications where reliability under high electrical and thermal stress is critical.

Replacement Considerations

Direct replacements must match the 4500 V rating, 450 A current capacity, and XHP™3 package dimensions. Verify that alternative components support the same AlSiC base plate requirement and meet the EN45545-2 HL3 certification if used in railway contexts.
