Single Zener Diodes Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm reel or cut-tape packaging specifications. Ensure the component matches the BZX384-Q series datasheet requirements for automotive-grade qualification before integration into final assemblies.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is required in compact automotive environments. The ±1% tolerance ensures tight voltage control compared to standard tolerance variants. Verify thermal management capabilities given the 300 mW dissipation limit in the small SOD-323 package.

Single Zener Diodes Part Context

This part belongs to the BZX384-Q series of low-power Zener diodes manufactured by Nexperia. The series offers multiple breakdown voltages from 2.4 V to 75 V across three tolerance grades: ±1%, ±2%, and ±5%. All variants share the same SOD-323 footprint and automotive qualification profile.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other BZX384-Q series variants with similar voltage ratings and tolerances, such as BZX384-A62-QX or BZX384-A75-QX, provided the circuit design accommodates the respective Zener voltage differences.
