Single Zener Diodes Procurement Notes

Verify the specific suffix GS18 against the manufacturer's latest datasheet to confirm pinout orientation and marking codes. Ensure the procurement channel provides original packaging documentation to validate authenticity. Cross-reference the lot code with Vishay's traceability records if required for quality assurance. Confirm that the delivered components match the SOD-323 package dimensions specified in the official mechanical drawing.

Single Zener Diodes Selection Notes

Select this component when a compact footprint is required alongside moderate power handling capabilities. The 200 mW dissipation rating suits low-current regulation tasks where thermal management is limited. Consider the 15 Ohm Zener impedance for applications requiring moderate dynamic resistance. The SOD-323 form factor facilitates automated assembly processes typical in modern PCB manufacturing environments.

Single Zener Diodes Part Context

This part belongs to the BZX384 series of small-signal Zener diodes from Vishay. The series is characterized by its use in general-purpose voltage regulation and clipping applications. The BZX384 line offers various voltage options within a standardized SOD-323 package, allowing designers to maintain consistent board layouts across different voltage requirements while benefiting from the reliability associated with Vishay's semiconductor manufacturing standards.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 8.2 V Zener voltage, 200 mW power rating, and SOD-323 package. Verify compatibility of the Zener impedance and leakage current specifications with the original circuit design constraints before substitution.
