• High-frequency applications

Single Zener Diodes Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm packaging details such as reel size or tape-and-reel specifications. Ensure the component meets AEC-Q101 requirements if intended for automotive use. Confirm that the ±5% tolerance variant aligns with design specifications before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a compact SOT323 footprint is required for voltage regulation. The ±5% tolerance offers cost-effective solutions where tighter precision is unnecessary. Consider the thermal resistance and power dissipation limits relative to the PCB copper area to ensure reliable operation under expected load conditions.

Single Zener Diodes Part Context

The BZX84W-Q series consists of 74 types with nominal voltages from 2.4 V to 75 V. The 'C' designation indicates the ±5% tolerance series. The 'Q' suffix denotes qualification according to AEC-Q101 standards. This series provides standardized breakdown voltages suitable for various low-power electronic circuits requiring stable reference voltages.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same family include other BZX84W-C22 variants with different suffixes indicating packaging differences. Cross-series replacements like BZX84-C22 may differ in package type (SOT-23 vs SOT-323) and power rating (250 mW vs 275 mW). Verify pinout compatibility and physical dimensions before substitution.
