Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct voltage and current ratings. Confirm that the component matches the required INT-A-pak mechanical dimensions for your heatsink interface. Check for any recent product change notices regarding material composition or manufacturing location updates before finalizing procurement orders.

Selection Notes

Select this component based on the required 1200 V blocking voltage and the expected load current profile relative to case temperature limits. Ensure the thermal management system can maintain the junction temperature below 150°C under maximum load conditions. Verify that the mounting torque specifications are met to ensure proper electrical contact and thermal performance.
