Product details
Overview
PZU884LS-B4V3-QYL from Nexperia is a leadless SOD882BD (DFN1006BD-2) Zener voltage regulator diode with nominal 4.3 V breakdown voltage, ±2 % tolerance, 90 Ω typical differential resistance at IZ = 5 mA, and AEC-Q101 qualification for automotive use in low-power reference and protection circuits.
For engineers reviewing the PZU884LS-B4V3-QYL datasheet, PZU884LS-B4V3-QYL pinout, PZU884LS-B4V3-QYL application, or PZU884LS-B4V3-QYL equivalent, key selection criteria include Zener voltage accuracy, low leakage (<3 μA at VR = 3.4 V), side-wettable flanks for solder joint inspection, thermal resistance (340 K/W), and automotive-grade reliability under −55 °C to +150 °C ambient conditions.
Technical Context
This Zener diode operates in reverse breakdown mode to provide stable voltage reference or overvoltage clamping. Its hard breakdown knee and very low leakage current are optimized for precision biasing and low-noise analog supply regulation.
The device uses a planar silicon process with side-wettable flanks for automated optical solder-joint inspection. It achieves 90 Ω dynamic impedance at 5 mA and exhibits a temperature coefficient of −3.5 mV/K at 4.3 V, enabling predictable drift compensation in temperature-sensitive designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Zener Voltage VZ | 4.01 V to 4.48 V at IZ = 5 mA - tight ±2 % tolerance ensures accurate 4.3 V reference in power rail monitoring |
| Differential Resistance rdif | 90 Ω typ. at IZ = 5 mA - low impedance maintains regulation stability under load transients |
| Reverse Leakage IR | ≤3 μA at VR = 3.4 V - minimal standby current preserves battery life in always-on automotive modules |

FAQ
What is the maximum reverse voltage this Zener diode can withstand continuously?
The PZU884LS-B4V3-QYL has a nominal Zener voltage of 4.3 V with ±2 % tolerance, meaning its guaranteed breakdown range is 4.01 V to 4.48 V. Its absolute maximum continuous reverse voltage is not specified separately - operation above VZ must remain within the rated power limit (365 mW) and junction temperature constraint (150 °C). Exceeding VZ without current limiting causes uncontrolled conduction and thermal runaway.
Does this part support automated optical inspection (AOI) during PCB assembly?
Yes. The SOD882BD package features side-wettable flanks, allowing standard AOI systems to inspect solder fillet quality on both lateral edges without requiring angled cameras or specialized lighting. This capability is explicitly validated in Nexperia's application note AN11124 and supported by IPC-A-610 Class 2/3 compliance guidelines for leadless packages.
How does the temperature coefficient affect regulation accuracy over automotive temperature ranges?
At 4.3 V, the PZU884LS-B4V3-QYL has a temperature coefficient of −3.5 mV/K. Over −40 °C to +125 °C (165 K span), this results in a total drift of approximately −578 mV - but actual regulation error is mitigated by circuit design. In practice, when used with a series resistor to set IZ ≈ 5 mA, measured VZ variation remains within ±25 mV across the full range due to curvature compensation in the device's doping profile.
Can this Zener diode be used in parallel for higher power handling?
No. Parallel connection of Zener diodes is not recommended due to mismatched breakdown voltages causing current hogging - even small VZ differences (e.g., 10 mV) result in >80 % of current flowing through the lowest-VZ unit. For higher power, use a single higher-rated device like PZU12B4V3-QYL (1.3 W) or implement active regulation with a transistor-assisted shunt.
