Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' indicates the required ±5% tolerance variant when sourcing. Confirm the GS18 designation aligns with standard packaging preferences. Ensure the selected distributor provides documentation confirming AEC-Q101 qualification status for the specific batch. Cross-reference the SOD-80 footprint dimensions against the target PCB layout to ensure mechanical compatibility.

Single Zener Diodes Selection Notes

Select this component when a 28 V reference is needed in a compact surface-mount form factor. The SOD-80 package offers space efficiency compared to axial leads. Consider the 500 mW power rating for thermal management in the final assembly. The wide temperature range supports operation in harsh environments without derating adjustments below specified limits.

Single Zener Diodes Part Context

This part belongs to the TZM series of Zener diodes from Vishay. The series includes various voltage ratings packaged in the same MiniMELF SOD-80 housing. The TZMC prefix typically denotes the automotive-grade AEC-Q101 qualified variants within the broader product line. These components are designed for general-purpose voltage regulation tasks.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers offering 28 V Zener diodes in SOD-80 packages with 500 mW ratings. Verify that alternative parts meet the same ±5% tolerance and AEC-Q101 qualification if automotive use is intended. Check for identical forward voltage characteristics at 200 mA to ensure circuit compatibility.
