BZX8850S-B27-QYL

Single Zener Diodes Overview

The Nexperia BZX8850S-B27-QYL is a low-current voltage regulator diode in the SOD882BD (DFN1006BD-2) leadless surface-mount package. It features a nominal working voltage of 27 V with ±2% tolerance, specified at a test current of 50 µA. The device supports a total power dissipation of up to 365 mW and operates within an ambient temperature range of -55 °C to +150 °C. It is qualified according to AEC-Q101 for automotive applications.

Single Zener Diodes Feature Summary

• Ultra-small leadless plastic package with side-wettable flanks
• Qualified according to AEC-Q101 for automotive use
• Optimized for low bias and portable battery-powered applications

Single Zener Diodes Applications

• Low-current general regulation functions

Single Zener Diodes Procurement Notes

Verify the specific suffix 'QYL' against official Nexperia documentation to confirm reel packaging details and exact marking codes. Ensure design compliance with AEC-Q101 requirements if deployed in automotive contexts. Confirm thermal management strategies align with the 365 mW dissipation limit under expected operating conditions.

Single Zener Diodes Selection Notes

Select this component for designs requiring precise voltage regulation in space-constrained environments. The ±2% tolerance series offers tighter accuracy than standard options. Consider the low test current specification when designing bias networks for battery-operated systems to minimize quiescent power consumption.

Single Zener Diodes Part Context

This part belongs to the BZX8850S-Q series of low-current voltage regulator diodes. The series provides a comprehensive range of nominal voltages from 1.8 V to 51 V in an ultra-small DFN1006BD-2 package. The 'B' designation indicates the ±2% tolerance variant, distinguishing it from the approximate ±5% 'C' series.

Single Zener Diodes Replacement Considerations

Direct substitutes include other BZX8850S-B27-Q variants with identical electrical specifications but different packaging or marking codes. Verify pinout compatibility and thermal characteristics before substitution.
