Single Diodes Procurement Notes

Verify the specific suffix and marking on the component body to ensure it matches the SDUR80P65WT designation exactly. Confirm that the package type is TO-247AD and check for any manufacturer-specific lot codes or date codes relevant to your quality requirements. Ensure compatibility with your assembly process regarding lead form and thermal interface materials.

Single Diodes Selection Notes

Select this component when designing circuits requiring fast switching speeds and high current capacity in a through-hole format. Compare the 32 ns reverse recovery time against slower alternatives to minimize switching losses. Evaluate the thermal resistance of the TO-247AD package relative to your heatsinking strategy to maintain junction temperatures within the specified limits under full load conditions.

Single Diodes Part Context
