Product details
Overview
PZU884LS-B11-QYL from Nexperia is a leadless Zener voltage regulator diode in DFN1006BD-2 (SOD882BD) package, rated for 11 V nominal Zener voltage with ±2 % tolerance, 60 Ω typical differential resistance at IZ = 5 mA, and qualified to AEC-Q101 for automotive power rail stabilization.
For engineers reviewing the PZU884LS-B11-QYL datasheet, PZU884LS-B11-QYL pinout, PZU884LS-B11-QYL application, or PZU884LS-B11-QYL equivalent, this device serves as a precision low-leakage voltage reference in space-constrained automotive ECUs, sensor biasing circuits, and low-power supply monitoring where side-wettable flanks enable automated optical inspection (AOI) and reliable reflow soldering.
Technical Context
This Zener diode operates in reverse breakdown mode with hard knee characteristics optimized for stable regulation at low currents (IZ = 5 mA), delivering tight voltage control under varying load and temperature conditions. Its differential resistance of 60 Ω ensures minimal output deviation across operating current changes.
Designed for automotive use, it features intentional low leakage current (≤0.1 μA at VR = 10 V) and a temperature coefficient of +5.4 mV/K at 11 V, enabling predictable drift behavior in ambient ranges from −55 °C to +150 °C. The side-wettable flank geometry supports IPC-A-610 Class 3 solder joint verification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11 V nominal, ±2 % tolerance - ensures precise 10.78–11.22 V regulation at IZ = 5 mA for stable reference generation |
| Differential Resistance (rdif) | 60 Ω max at IZ = 5 mA - minimizes output voltage shift under dynamic load transients |
| Reverse Current (IR) | ≤0.1 μA at VR = 10 V - reduces quiescent power loss in always-on automotive subsystems |
| Power Dissipation (Ptot) | 365 mW at Tamb = 25 °C on FR4 - supports continuous operation in compact PCB layouts without forced cooling |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables deployment in engine bay, transmission control, and ADAS modules |
| Package | DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm - ultra-small footprint with side-wettable flanks for AOI-compatible assembly |
| AEC-Q101 Qualified | Qualified per Stress Test Qualification for Discrete Semiconductors - certified for automotive production use without additional qualification |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal leadless plastic package with side-wettable flanks, 0.65 mm pitch, and cathode indicated by a marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity marker aligns with PCB silkscreen bar for automated placement verification |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction enabling Zener breakdown conduction |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder fillets on both side edges - critical for zero-defect automotive manufacturing |
| Hard breakdown knee | Sharp, low-noise transition into regulation at 11 V - improves stability in feedback loops and reference buffers |
| Low dynamic impedance | 60 Ω typical at 5 mA - maintains <±10 mV output variation across ±1 mA load steps in sensing applications |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling - eliminates need for customer requalification |
| Ultra-small footprint | 1.0 mm × 0.6 mm body - saves >70 % board area vs. SOD-323 while maintaining thermal performance via copper pad exposure |
Applications
| Engine Control Unit (ECU) Power Monitoring | Automotive Cabin Sensor Biasing |

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-C11 | ±5 % tolerance, SOT-23 package (2.9 mm × 1.3 mm), 350 mW Ptot, rdif = 90 Ω | Larger footprint, higher dynamic impedance, no AEC-Q101 qualification | Select for cost-sensitive non-automotive consumer designs where size and qualification are secondary |
| MMSZ5240B | ±5 % tolerance, SOD-123 package (2.7 mm × 1.4 mm), 500 mW Ptot, rdif = 17 Ω | Higher power rating but larger size, no side-wettable flanks, not AEC-Q101 qualified | Choose when higher surge handling is required and AOI compatibility is not mandatory |
Compared with BZX84-C11 and MMSZ5240B, PZU884LS-B11-QYL delivers tighter voltage control, automotive qualification, and 70 % smaller PCB area - making it optimal for next-generation ECU and ADAS modules where space, reliability, and regulatory compliance are prioritized.

FAQ
What is the maximum reverse voltage this Zener can sustain before breakdown?
The PZU884LS-B11-QYL has a nominal Zener voltage of 11 V with ±2 % tolerance, meaning breakdown occurs between 10.78 V and 11.22 V at IZ = 5 mA. It is not rated for sustained operation above 11.22 V in regulation mode; exceeding this risks thermal runaway if power dissipation limits are breached.
Does this part support automated optical inspection (AOI) during PCB assembly?
Yes - its DFN1006BD-2 package features side-wettable flanks, allowing AOI systems to inspect solder fillet formation on both lateral edges. This meets IPC-A-610 Class 3 requirements and is validated in Nexperia's reflow footprint documentation (sod882bd_fr).
How does the leakage current behave at elevated temperatures?
At VR = 10 V, leakage is ≤0.1 μA at 25 °C and rises to ≤1.0 μA at 150 °C per datasheet Table 8. This controlled increase maintains regulation integrity while avoiding excessive standby current in high-temp automotive zones.
Can this Zener replace older through-hole Zeners like 1N4740A in new designs?
It can functionally replace 1N4740A (10 V, ±5 %) in regulation roles, but only if layout accommodates the 1.0 mm × 0.6 mm DFN footprint and thermal design accounts for lower Ptot (365 mW vs. 1 W). Its tighter tolerance and AEC-Q101 qualification make it superior for automotive, but not a drop-in mechanical replacement.
