Single Zener Diodes Procurement Notes

Verify the specific suffix GS18 corresponds to the SOD-123-2 package and ±2% tolerance variant, as Vishay uses distinct suffixes for different tolerances and packaging types. Confirm RoHS3 compliance status and ensure the component matches the required AEC-Q101 qualification level for your specific application environment. Cross-reference the manufacturer part number with official datasheets to avoid confusion with similar series parts like MMSZ5247C-HE3-18.

Single Zener Diodes Selection Notes

Select this component when a stable 17 V reference with high accuracy is required in an automotive or industrial setting. The ±2% tolerance makes it suitable for precision applications where standard 5% Zeners are insufficient. Ensure the 500 mW power rating aligns with the expected thermal dissipation in the final assembly. The SOD-123-2 package offers a balance between power handling and board space efficiency.

Single Zener Diodes Part Context

This part belongs to the MMSZ524x series of axial and surface-mount Zener diodes designed for general-purpose and automotive applications. The series is known for its robust construction and compliance with automotive quality standards. Vishay's GS18 suffix typically denotes specific packaging and material compliance options within their broader diode portfolio, ensuring consistency across production batches.

Single Zener Diodes Replacement Considerations

Publicly confirmed direct substitute part numbers for TZM5247C-GS18 were not found in the provided source data. Verify compatibility with other 17 V, 500 mW, ±2% tolerance Zener diodes in the SOD-123 package from Vishay or other manufacturers, ensuring AEC-Q101 certification if automotive use is intended.
