BZX58550-B13-QX

Single Zener Diodes Overview

The Nexperia BZX58550-B13-QX is a low-current voltage regulator diode in an SOD523 (SC-79) surface-mounted package. It features a nominal working voltage of 13 V with ±2% tolerance, specified at a test current of 50 μA. The device supports a total power dissipation of up to 300 mW and operates within a temperature range of -55 °C to +150 °C. It is qualified according to AEC-Q101 for automotive applications.

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 standards for use in automotive applications.

Single Zener Diodes Applications

• Low-current general regulation functions

Single Zener Diodes Procurement Notes

Verify the specific suffix 'QX' against the official datasheet to confirm packaging details, as ordering suffixes may indicate variations in reel or tape specifications. Ensure the component meets the required AEC-Q101 qualification status if intended for automotive deployment. Cross-reference the marking code '5Y' with the manufacturer's documentation to validate authenticity and production batch information before integration into designs.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is required under minimal bias conditions typical of battery-operated devices. The ±2% tolerance series offers tighter voltage accuracy compared to standard ±5% variants. Consider the SOD523 package dimensions for high-density circuit board layouts where space constraints are critical for the overall system design.

Single Zener Diodes Part Context

This part belongs to the BZX58550-Q series of low-current voltage regulator diodes manufactured by Nexperia. The series provides a comprehensive range of nominal working voltages from 1.8 V to 51 V in an ultra-small plastic SMD package. The 'B' designation indicates the ±2% tolerance variant within this product family.

Single Zener Diodes Replacement Considerations

Consult the official Nexperia datasheet for direct cross-references. Verify that any substitute maintains the SOD523 footprint, 13 V nominal voltage, and ±2% tolerance requirements while meeting AEC-Q101 automotive qualifications.
