Procurement Notes

Verify the component against official Micro Commercial Components datasheets to confirm authenticity. Ensure the ordering suffix matches the required tape and reel configuration. Purchase only from authorized distributors to avoid counterfeit parts. Confirm RoHS compliance and halogen-free status if specific environmental constraints apply to your assembly process.

Selection Notes

Select this component when automotive qualification (AEC-Q101) is mandatory for small-signal switching applications. The SOD-323 package offers a compact footprint compared to larger alternatives. Consider the 75V reverse voltage limit and 250mA continuous current rating during circuit design. Verify thermal management requirements given the 200mW power dissipation capability.

Part Context

This part belongs to the 1N4448 series of silicon switching diodes manufactured by Micro Commercial Components. It serves as a surface-mount equivalent to through-hole variants, providing similar electrical performance in a smaller form factor. The HE3 designation indicates specific manufacturing enhancements regarding environmental compliance and lead finish.

Replacement Considerations

Direct replacements include the standard 1N4448WX-TP or other AEC-Q101 qualified SOD-323 switching diodes with matching 75V and 250mA ratings.
