Procurement Notes

Verify the specific suffix 'C9' against the manufacturer's official datasheet to confirm packaging details and compliance status. Ensure the component meets the required AEC-Q101 qualification level for your specific application environment. Cross-reference the TO-220FN-3 package dimensions with your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a high-current, automotive-qualified Schottky diode is required in a through-hole format. The 150 V rating and 40 A current capacity make it suitable for medium-voltage DC bus applications. Consider the TO-220FN-3 package for effective heat dissipation without requiring additional external heatsinking in moderate load scenarios.
