Procurement Notes

Verify component authenticity through authorized channels as this part is listed as obsolete. Confirm that the D1 package footprint matches existing board layouts. Check for RoHS compliance status relative to specific project requirements. Ensure replacement strategies are evaluated due to end-of-life status. Validate thermal management solutions against the 150°C junction limit.

Selection Notes

Select this module when designs require a 100 A continuous current rating with 800 V blocking capability in a common cathode arrangement. The D1 package is suitable for applications needing direct base mounting for heat sinking. Consider the standard recovery time if switching frequency constraints exist. Evaluate thermal resistance parameters to ensure adequate cooling infrastructure is available for the expected operating conditions.
