Single Zener Diodes Procurement Notes

Verify the specific ordering suffix -QYL against the manufacturer's latest documentation to confirm packaging details and availability status. Ensure the component meets the required AEC-Q101 qualification if intended for automotive use. Cross-reference the marking code '7F' with official Nexperia tables to validate authenticity and production batch information before integration into designs.

Single Zener Diodes Selection Notes

Select this component for circuits requiring precise voltage regulation at very low currents. The ±5% tolerance series offers a balance between cost and precision for general-purpose applications. Consider the DFN1006BD-2 package dimensions when designing PCB footprints, ensuring adequate copper area for thermal dissipation within the 365 mW limit. Verify that the operating temperature range aligns with the system's environmental requirements.

Single Zener Diodes Part Context

This part belongs to the Nexperia BZX8850S-Q series of low-current voltage regulator diodes. The series provides a wide working voltage range from nominal 1.8 V to 51 V in an ultra-small form factor. The C-series designation indicates a standard ±5% voltage tolerance. These devices are designed to replace larger packages in high-density circuit designs while maintaining reliability for automotive and portable electronics markets.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include other BZX8850S-C variants with different Zener voltages, such as BZX8850S-C8V2-Q or BZX8850S-C10-Q, provided the voltage requirement changes. For identical specifications, verify equivalent parts from other manufacturers offering AEC-Q101 qualified Zener diodes in the SOD882BD package.
