Single Zener Diodes Procurement Notes

Verify the specific suffix A-08 against official Vishay documentation to confirm packaging details, as ordering suffixes may indicate variations in tape-and-reel specifications or manufacturing origin. Ensure compatibility with existing PCB footprints for the SOD-123 package. Cross-reference the part status with current manufacturer announcements to account for potential obsolescence or substitution recommendations.

Single Zener Diodes Selection Notes

Select this component when a 5.6 V Zener reference is required in a low-power surface-mount application. The SOD-123 package offers a balance between power handling and board space efficiency. Consider the 500 mW power rating relative to expected surge currents and duty cycles. Verify that the operating temperature range meets the environmental requirements of the target system.

Single Zener Diodes Part Context

This part belongs to the MMSZ4690 series of Zener diodes from Vishay. The HE3 designation indicates a Halogen-free and Green product variant, adhering to strict environmental standards. The series is designed for general-purpose voltage regulation tasks where reliability and compliance are prioritized over high-power handling capabilities.

Single Zener Diodes Replacement Considerations

Public confirmed substitutes include MMSZ4690-E3-08 and MMSZ4690-TP. Verify pinout and electrical tolerances before substitution.
