BZX58550-B6V2-QX

Single Zener Diodes Overview

The Nexperia BZX58550-B6V2-QX is a low-current voltage regulator diode housed in an SOD523 (SC-79) surface-mounted package. It features a nominal working voltage of 6.2 V with ±2% tolerance. The device operates at a test current of 50 μA, supporting a total power dissipation of up to 300 mW and a non-repetitive peak reverse power dissipation of 40 W. It functions within an ambient temperature range of -55 °C to +150 °C and is qualified according to AEC-Q101 standards.

Single Zener Diodes Feature Summary

• Designed for low bias and portable battery-powered applications due to specification at a low test current of 50 μA.
• Features intentional minor rise of leakage current for optimized fast switching and noise reduction.
• Qualified according to AEC-Q101 and recommended for use in automotive applications.

Single Zener Diodes Applications

• Low-current general regulation functions

Single Zener Diodes Procurement Notes

Verify the specific suffix 'Q' indicates AEC-Q101 qualification for automotive suitability. Confirm the 'B' designation corresponds to the ±2% tolerance series rather than the standard ±5% variant. Ensure the ordering part number matches the exact voltage code required for the design specifications.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is required in space-constrained designs utilizing the SOD523 footprint. The low test current specification makes it suitable for energy-efficient circuits where minimal quiescent current draw is critical. Verify thermal management requirements against the 300 mW dissipation limit under expected operating conditions.

Single Zener Diodes Part Context

This component belongs to the BZX58550-Q series of low-current voltage regulator diodes from Nexperia. The series offers a wide working voltage range from 1.8 V to 51 V in an ultra-small plastic SMD package. The Q-series specifically denotes automotive qualification, expanding the standard BZX585 line for high-reliability environments.

Single Zener Diodes Replacement Considerations

Direct substitutes include other BZX58550-B6V2 variants from Nexperia or equivalent Zener diodes in SOD523 packages with matching 6.2 V nominal voltage and ±2% tolerance. Verify that any replacement also meets AEC-Q101 requirements if automotive application is intended.
