PZU884LS-B3V9-QYL

Single Zener Diodes Overview

The Nexperia PZU884LS-B3V9-QYL is a general-purpose Zener voltage regulator diode featuring a nominal working voltage of 3.9 V with ±2% tolerance. It is housed in an ultra-small SOD882BD (DFN1006BD-2) leadless surface-mounted package with side-wettable flanks. The device supports a total power dissipation of 365 mW and a non-repetitive peak reverse power dissipation of 40 W. Operating 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

• Leadless ultra-small plastic package with side-wettable flanks suitable for surface-mounted design
• Qualified according to AEC-Q101 and recommended for use in automotive applications
• Very low dynamic impedances at low currents, very low leakage current, and hard breakdown knee

Single Zener Diodes Applications

• General regulation functions

Single Zener Diodes Procurement Notes

Verify the specific suffix 'QYL' against official Nexperia ordering lists, as datasheets typically list standard suffixes like '-Q'. Confirm package dimensions match DFN1006BD-2 requirements. Ensure design accounts for the specified thermal resistance and power dissipation limits under actual operating conditions. Cross-reference marking codes for quality assurance during assembly.

Single Zener Diodes Selection Notes

Select this component for designs requiring precise voltage regulation in compact spaces. The ±2% tolerance series offers tighter accuracy than the ±5% option. Consider the low leakage current and hard breakdown characteristics for stable performance in sensitive circuits. Verify compatibility with automated assembly processes due to the leadless package type.

Single Zener Diodes Part Context

This part belongs to the PZU884LS-Q series of Zener voltage regulator diodes from Nexperia. The series covers a wide working voltage range from 2.4 V to 51 V. It shares the same DFN1006BD-2 package and AEC-Q101 qualification across the family, offering consistent form factor and reliability standards for various voltage reference needs.

Single Zener Diodes Replacement Considerations

Direct substitutes include other parts from the PZU884LS-Q series with similar voltage ratings and tolerances, such as PZU884LS-B3V6-Q or PZU884LS-B4V3-Q, provided the voltage difference is acceptable for the application.
