Procurement Notes

Verify that the ordered part number matches ACGRKM4001-HF exactly, ensuring the suffix indicates the correct 50V rating and KM package variant. Confirm AEC-Q101 compliance requirements are met for the specific end-use application. Check datasheet revisions for any recent product change notifications that may affect mechanical or electrical specifications prior to final design integration.

Selection Notes

Select this component when a 1A current rating and 50V blocking voltage are required in a small surface-mount footprint. The AEC-Q101 qualification makes it suitable for automotive environments where higher reliability standards apply compared to commercial grade parts. Ensure the SOD-123F package dimensions align with the PCB layout constraints and thermal management requirements of the target design.

Part Context

This component belongs to Comchip Technology's series of SMD general purpose rectifiers. The 'KM' designation refers to the specific SOD-123F package style used for this device. The 'HF' suffix typically indicates halogen-free manufacturing, adhering to environmental standards. This family focuses on providing reliable rectification solutions for both industrial and automotive markets using standardized surface-mount technologies.

Replacement Considerations

Direct substitutes must match the 1A current, 50V voltage, and SOD-123F package. Verify pinout compatibility and thermal characteristics before substitution. Cross-reference with other manufacturers offering AEC-Q101 qualified standard recovery diodes in identical packages if availability is constrained.
