• Leadless very small Surface-Mounted Device plastic package

Single Zener Diodes Applications

• General regulation functions
• High-frequency applications

Single Zener Diodes Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm packaging details such as reel or cut tape configuration. Ensure the component meets AEC-Q101 requirements if intended for automotive use. Confirm that the marking code corresponds to the correct voltage rating before integration into production designs.

Single Zener Diodes Selection Notes

Select this component when a compact SMD solution is required for voltage regulation within the automotive sector. The ±5% tolerance suits standard applications where tighter precision is unnecessary. Consider the low reverse leakage current and high operating temperature capability for reliable performance in demanding environments.

Single Zener Diodes Part Context

This part belongs to the BZX84W-Q series, which provides general-purpose Zener diodes in a SOT323 package. The series offers nominal voltages from 2.4 V to 75 V with both ±2% and ±5% tolerance options. The Q-series designation indicates qualification for automotive standards, distinguishing it from standard commercial variants.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same family include BZX84W-B20-Q for tighter tolerance. Other BZX84W-C20 variants without the Q suffix may serve as replacements if automotive qualification is not required.
