Product details
Overview
PZU884LS-B33-QYL from Nexperia is a 33 V ±2 % tolerance Zener voltage regulator diode in a DFN1006BD-2 (SOD882BD) leadless SMD package with side-wettable flanks, rated for 365 mW total power dissipation and qualified to AEC-Q101 for automotive use. It delivers stable reference voltage regulation in compact power management circuits, with differential resistance of 250 Ω at 5 mA and reverse current ≤0.05 μA at 25 V.
For engineers reviewing the PZU884LS-B33-QYL datasheet, PZU884LS-B33-QYL pinout, PZU884LS-B33-QYL application, or PZU884LS-B33-QYL equivalent, key selection criteria include its 33 V nominal Zener voltage, ultra-small 1.0 mm × 0.6 mm footprint, side-wettable flank solderability, AEC-Q101 qualification, and low leakage performance in automotive body electronics and infotainment power rails.
Technical Context
This Zener diode operates in reverse breakdown to maintain a precise 33 V reference under varying load and temperature conditions. Its hard breakdown knee and low dynamic impedance (250 Ω at IZ = 5 mA) ensure tight regulation stability during transient load shifts.
Designed for automotive-grade reliability, it features intentional low leakage (<0.05 μA at VR = 25 V) and a temperature coefficient of +27.4 mV/K at 33 V, enabling predictable drift compensation in voltage reference and overvoltage protection circuits across −40 °C to +125 °C ambient.
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-C33,115 | 33 V ±5 % tolerance, SOT-23 package, 300 mW Ptot, no AEC-Q101 qualification | Larger footprint (2.9 mm × 1.3 mm), higher leakage (>100 nA), unsuitable for automotive production | Select only for cost-sensitive industrial prototypes where AEC-Q101 is not required |
| MMSZ5257ET1G | 33 V ±5 %, SOD-123 package, 500 mW Ptot, AEC-Q101 qualified, but 2.7 mm × 1.4 mm size | Higher power rating but 6× larger area; lacks side-wettable flanks for AOI compatibility | Prefer when higher surge capability is needed and board space allows; avoid if AOI or miniaturization is mandatory |
Compared with BZX84-C33,115 and MMSZ5257ET1G, PZU884LS-B33-QYL uniquely combines AEC-Q101 qualification, ±2 % tolerance, side-wettable flanks, and sub-1 mm² footprint-making it the only option meeting full automotive production requirements for space-constrained, high-reliability Zener regulation.

FAQ
What is the maximum non-repetitive peak reverse power the PZU884LS-B33-QYL can withstand?
The PZU884LS-B33-QYL supports up to 40 W non-repetitive peak reverse power dissipation (PZSM) for pulse durations of 100 μs at Tj = 25 °C prior to surge. This rating enables robust transient suppression in automotive load-dump scenarios without permanent degradation.
How does the side-wettable flank design benefit manufacturing?
The side-wettable flanks on the DFN1006BD-2 package allow automated optical inspection (AOI) to verify solder joint quality without requiring X-ray equipment. This reduces final-test cost and increases yield assurance in high-volume automotive PCB assembly lines.
Is the PZU884LS-B33-QYL suitable for use in ASIL-B systems?
While the PZU884LS-B33-QYL itself is not ASIL-certified (as Zeners are passive components), its AEC-Q101 qualification, guaranteed parametric stability over temperature, and proven field reliability make it suitable for inclusion in ASIL-B system designs-provided system-level FMEDA and fault injection analysis confirm compliance.
What is the typical temperature coefficient at 33 V and how does it affect circuit design?
The PZU884LS-B33-QYL has a typical temperature coefficient of +27.4 mV/K at 33 V. This positive drift means output voltage rises ~0.9 V over a 33 K ambient increase; designers must account for this in precision references using temperature-compensating resistor networks or calibration algorithms.
