BZX8850S-B3V3-QYL

Single Zener Diodes Overview

The BZX8850S-B3V3-QYL is a low-current voltage regulator diode from the Nexperia BZX8850S-Q series, housed in an ultra-small DFN1006BD-2 (SOD882BD) leadless surface-mount package with side-wettable flanks. It operates within a nominal working voltage range of 1.8 V to 51 V and features a total power dissipation capability of up to 365 mW. The device is specified at a low test current of 50 μA, making it suitable for low bias applications. It offers two tolerance series: ±2% (B-series) and approximately ±5% (C-series). The component is qualified according to AEC-Q101 standards.

Single Zener Diodes Feature Summary

• Designed for low bias and portable battery-powered applications through 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 'QYL' against the manufacturer's official ordering information to confirm packaging details, as datasheets typically list standard suffixes like '-Q'. Ensure the design accounts for the DFN1006BD-2 footprint dimensions and reflow soldering requirements. Confirm that the ±2% tolerance aligns with circuit requirements. Check for any Product Change Notifications regarding manufacturing updates.

Single Zener Diodes Selection Notes

Select this component when space-constrained designs require a leadless SMD package with side-wettable flanks for improved solderability. Choose the B-series for tighter ±2% voltage tolerance or C-series for approximate ±5%. Consider the low test current specification for battery-operated devices where minimizing quiescent current is critical. Verify thermal resistance characteristics if operating near maximum power dissipation limits.

Single Zener Diodes Part Context

This part belongs to the Nexperia BZX8850S-Q series of low-current voltage regulator diodes. The series provides a comprehensive range of nominal working voltages from 1.8 V to 51 V in an ultra-small plastic package. The Q-series designation indicates qualification for automotive applications, meeting AEC-Q101 stress test standards. The family includes variants with different voltage ratings and tolerance levels to support diverse electronic design needs.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include other BZX8850S-B/Q types with similar voltage ratings, such as BZX8850S-B3V0-QYL or BZX8850S-B3V6-QYL, provided the voltage tolerance and package match. Cross-package replacements are not directly interchangeable due to pinout and footprint differences.
