Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm exact technical variants, as suffixes may indicate differences in packaging or testing standards. Confirm availability status directly with authorized distributors, as supply levels can fluctuate. Ensure the procurement channel is an authorized partner to guarantee component authenticity and traceability. Cross-reference the manufacturer part number with any internal project codes before finalizing orders.

Selection Notes

Select this module based on its 1800 V blocking capability and 250 A/µs diT/dt rating to ensure compatibility with the target circuit's voltage and current surge requirements. Evaluate the 0.112 K/W thermal resistance against the system's cooling infrastructure to maintain junction temperatures below the 130 °C limit. Verify that the 50 mm press-fit package dimensions align with the available mechanical space and mounting constraints in the design.
