Procurement Notes

Verify the specific suffix C9 against the official datasheet to confirm packaging details, as suffixes often denote tube or bulk variations. Ensure the component meets AEC-Q101 requirements if used in automotive designs. Cross-reference the manufacturer's latest documentation for any obsolescence notices or alternative recommendations, as this series may have updated variants.

Selection Notes

Select this component when a through-hole Schottky diode with automotive qualification is required. The 150 V rating and 40 A current capacity suit medium-power applications. Consider the TO-220FN-3 package for heat dissipation needs. Compare forward voltage drop specifications against system efficiency targets. Verify that the common cathode topology aligns with the intended bridge or synchronous rectifier circuit architecture.
