Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required packaging configuration. Ensure compliance with RoHS directives as defined in the material categorization documentation. Validate thermal interface requirements against the specified mounting torque values to maintain proper heat dissipation during operation.

Selection Notes

Select this component based on the 1200 V blocking capability and the required continuous current ratings at specific case temperatures. Evaluate the switching loss parameters against the target operating frequency range between 8 kHz and 30 kHz. Consider the positive temperature coefficient of the on-state voltage for potential parallel operation configurations. Verify that the gate drive voltage aligns with the specified 15 V threshold for optimal conduction.
