Procurement Notes

Verify the specific datasheet revision and manufacturing lot details upon receipt to ensure compliance with technical specifications. Confirm that the component matches the TO-268-3 package dimensions and pinout configuration required by the target circuit design. Check for any obsolescence notices or lifecycle status updates from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a single IGBT with 1.2 kV blocking voltage and 90 A continuous current handling is required. The TO-268-3 package facilitates direct board mounting or heatsink attachment. Ensure the driving circuit can accommodate the specified gate-emitter voltage limits and provide adequate thermal management to maintain junction temperatures within the 150 °C maximum limit during peak load conditions.

Part Context

This part belongs to the IXGT series of high-power IGBTs from IXYS, designed for medium to high-power conversion applications. The series typically offers a balance of low conduction losses and fast switching speeds. The TO-268-3 package provides a cost-effective solution for industrial applications requiring reliable high-voltage switching without the complexity of module integration.

Replacement Considerations

Consult official IXYS documentation for verified cross-reference part numbers. Ensure any substitute maintains identical voltage ratings, current capabilities, and package compatibility.
