Product details
Overview
PZU884LS-B4V7-Q from Nexperia is a ±2 % tolerance Zener voltage regulator diode in DFN1006BD-2 (SOD882BD) package, rated for 4.7 V nominal breakdown voltage at 5 mA, with differential resistance of 800 Ω (IZ = 5 mA), leakage current ≤2 μA at VR = 4.42 V, and qualified to AEC-Q101 for automotive power rail stabilization.
For engineers reviewing the PZU884LS-B4V7-Q datasheet, PZU884LS-B4V7-Q pinout, PZU884LS-B4V7-Q application, or PZU884LS-B4V7-Q equivalent, this device supports precision low-current voltage reference, ESD-protected I/O clamping, and post-regulator feedback sensing in space-constrained automotive ECUs and ADAS sensor modules.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with hard knee characteristics optimized for stable regulation at low currents (IZ = 0.5 mA to 5 mA). Its differential resistance remains ≤800 Ω across the specified test current, and temperature coefficient is −3.5 mV/K at IZ = 5 mA, enabling predictable drift compensation in analog front-ends.
The device features side-wettable flanks for automated optical solder-joint inspection and achieves 365 mW steady-state power dissipation on standard FR4 PCBs. It sustains non-repetitive 40 W surge pulses (tp = 100 μs) while maintaining junction temperature ≤150 °C under ambient conditions from −55 °C to +150 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C4V7,115 | ±5 % tolerance, SOT-23 package (3.0 mm × 1.4 mm), 150 mW Ptot, no AEC-Q101 qualification | Larger footprint, higher leakage (>5 μA), unsuitable for automotive under-hood use | Select only for cost-sensitive consumer-grade boards where AEC-Q101 and space constraints are not required |
| MMSZ4704T1G | ±5 % tolerance, SOD-123 package (3.7 mm × 1.6 mm), 500 mW Ptot, AEC-Q101 qualified | Higher power rating but 6× larger area; lacks side-wettable flanks for AOI | Prefer when higher surge handling is needed and board space permits; avoid if AOI or miniaturization is mandatory |
Compared with BZX84-C4V7,115 and MMSZ4704T1G, PZU884LS-B4V7-Q uniquely combines AEC-Q101 qualification, ±2 % tolerance, DFN1006BD-2 miniaturization, and side-wettable flanks-making it the only option meeting all four requirements for next-gen automotive sensor nodes.

FAQ
What is the maximum continuous reverse power dissipation for PZU884LS-B4V7-Q at 25 °C ambient?
The maximum continuous reverse power dissipation is 365 mW when mounted on a standard FR4 PCB with single-sided 70 μm copper and tin plating. This value assumes natural convection cooling and is derated linearly above 25 °C ambient per the device's thermal resistance of 340 K/W.
Does PZU884LS-B4V7-Q support automated optical inspection (AOI) of solder joints?
Yes. Its DFN1006BD-2 package features side-wettable flanks, allowing AOI systems to verify solder fillet formation without requiring X-ray inspection. This capability is confirmed in Nexperia's package outline documentation (SOD882BD, Issue date 20-06-22).
How does the temperature coefficient affect regulation accuracy over automotive temperature range?
With a temperature coefficient of −3.5 mV/K at IZ = 5 mA, the Zener voltage shifts approximately −0.35 V from −40 °C to +125 °C. This drift is predictable and can be compensated in closed-loop feedback systems; the ±2 % initial tolerance dominates total error budget in most implementations.
Can PZU884LS-B4V7-Q be used as a bidirectional ESD clamp on high-speed data lines?
Yes. Its forward voltage is ≤0.9 V at 10 mA and reverse breakdown is tightly controlled at 4.7 V, enabling effective clamping of both positive and negative transients. However, its 325 pF capacitance at 0 V limits use to lines operating below ~30 MHz-such as LIN, SENT, or low-speed CAN.
