PZU884LS-B2V4-QYL

Single Zener Diodes Overview

The PZU884LS-B2V4-QYL is a Zener voltage regulator diode from Nexperia, housed in an ultra-small SOD882BD (DFN1006BD-2) leadless surface-mounted package with side-wettable flanks. It belongs to the B-series, offering a nominal Zener voltage of 2.4 V with a tight tolerance of ±2%. The device is qualified according to AEC-Q101 standards, making it suitable for automotive applications. It features very low dynamic impedances at low currents and a hard breakdown knee, ensuring stable regulation performance.

Single Zener Diodes Feature Summary

• AEC-Q101 qualified for automotive application reliability
• Very low dynamic impedances at low currents with a hard breakdown knee

Single Zener Diodes Applications

• General regulation functions
• Automotive electronic circuits

Single Zener Diodes Procurement Notes

Verify the specific suffix -QYL against official Nexperia documentation to confirm tape-and-reel packaging details and ensure compliance with required automotive quality standards. Confirm that the B-series designation matches the required ±2% tolerance for your circuit design. Cross-reference the DFN1006BD-2 footprint dimensions during PCB layout to ensure accurate placement and soldering.

Single Zener Diodes Selection Notes

Select this component when a precise 2.4 V reference is needed in space-constrained designs requiring high reliability. The B-series provides tighter tolerance than the C-series, which is critical for precision regulation. Ensure the operating current remains within the range where the specified low dynamic impedance and hard knee characteristics are maintained for optimal performance.

Single Zener Diodes Part Context

This part is part of the PZU884LS series, designed for general-purpose Zener regulation in compact electronics. The LS variant specifically denotes the SOD882BD package with side-wettable flanks, enhancing solder joint visibility and reliability compared to standard packages. It complements other Nexperia voltage regulator diodes like the BZX884 series but offers distinct package and electrical characteristics tailored for modern surface-mount assembly.

Single Zener Diodes Replacement Considerations

Direct substitutes include other Nexperia Zener diodes in the SOD882BD package with similar voltage and tolerance, such as PZU884LS-C2V4-QYL, though tolerance differs. Verify pinout compatibility and thermal characteristics before substitution. Generic equivalents may lack AEC-Q101 qualification.
