Procurement Notes

Verify the specific suffix and tape-and-reel or tray packaging configuration against the official Infineon ordering code list before procurement. Confirm that the requested quantity matches the standard minimum order unit defined in the current distributor catalog. Ensure the component lot date aligns with project timeline requirements to avoid obsolescence risks associated with long-term storage.

Selection Notes

Select this module when designing circuits requiring 1200 V blocking voltage and continuous currents around 400 A. Evaluate the thermal resistance parameters against the intended heatsink design to ensure junction temperature limits are not exceeded during peak load operations. Consider the gate charge specifications for driver selection to optimize switching transitions and minimize power dissipation in the control stage.

Part Context

This component belongs to Infineon's portfolio of insulated gate bipolar transistors aimed at medium-power industrial applications. It represents a generation of devices engineered to improve system efficiency through reduced switching losses compared to previous technologies. The module form factor allows for direct mounting onto standardized cooling structures, facilitating integration into compact power electronic assemblies.

Replacement Considerations

Direct replacements must match the 1200 V / 400 A rating and compatible pinout. Verify thermal interface dimensions and electrical isolation requirements. Cross-reference datasheet parameters such as Vce(sat) and switching times to ensure equivalent performance in the existing circuit topology without redesigning the gate drive network.
