Product details
Overview
PZU884LS-B9V1-QYL from Nexperia is a leadless SOD882BD (DFN1006BD-2) Zener voltage regulator diode with nominal 9.1 V breakdown voltage, ±2 % tolerance, 6 Ω typical differential resistance at IZ = 5 mA, and AEC-Q101 qualification for automotive use in power rail stabilization and overvoltage protection circuits.
For engineers reviewing the PZU884LS-B9V1-QYL datasheet, PZU884LS-B9V1-QYL pinout, PZU884LS-B9V1-QYL application, or PZU884LS-B9V1-QYL equivalent, key selection criteria include its side-wettable flank package for automated optical inspection, low leakage current (<0.5 μA at VR = 7.3 V), hard breakdown knee, and thermal resistance of 340 K/W on FR4 PCB.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its design targets precision regulation in space-constrained automotive ECUs and ADAS sensor modules where board area and solder joint reliability are critical.
The device features two tolerance series (±2 % and ≈±5 %) and two performance variants: the 'B' series (e.g., B9V1) delivers very low dynamic impedance and minimal leakage, while the 'C' series prioritizes fast switching and noise reduction via controlled leakage rise - confirmed by AN90031.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 9.1 V - Stable regulation point at IZ = 5 mA; supports 12 V rail clamping and feedback reference in LDOs. |
| Tolerance | ±2 % - Tight voltage accuracy enables high-precision analog sensing and ADC reference buffering without trimming. |
| Differential Resistance | 6 Ω (typ.) at IZ = 5 mA - Low impedance ensures minimal output voltage shift under load transients (ΔVZ ≈ 30 mV for ΔIZ = 5 mA). |
| Reverse Leakage Current | <0.5 μA at VR = 7.3 V - Enables ultra-low quiescent current operation in always-on automotive subsystems. |
| Total Power Dissipation | 365 mW - Sufficient for continuous regulation in 5–10 mA bias applications on standard FR4 PCBs. |
| Junction Temperature Range | −55 °C to +150 °C - Validated for under-hood automotive environments per AEC-Q101 stress testing. |
| Package | SOD882BD (DFN1006BD-2) - 1.0 mm × 0.6 mm × 0.47 mm leadless package with side-wettable flanks for AOI-compatible reflow soldering. |
Pinout & Package
SOD882BD (DFN1006BD-2) is a 2-terminal, leadless surface-mount 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; reverse-bias anode-to-cathode voltage establishes Zener conduction. |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes current path during regulation or transient clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, improving manufacturing yield in automotive SMT lines. |
| Hard breakdown knee | Sharp, well-defined Zener transition minimizes voltage uncertainty near regulation threshold - critical for accurate overvoltage detection. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling - suitable for engine control and body electronics. |
| Low thermal resistance | Rth(j-a) = 340 K/W on standard FR4 - allows sustained 365 mW dissipation without external heatsinking in compact layouts. |
| Ultra-small footprint | 1.0 mm × 0.6 mm body area - saves >70 % board space vs. traditional SOD-123 packages, enabling denser ECU designs. |
Applications
| Engine Control Unit (ECU) Power Monitoring | ADAS Camera Module Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C9V1,115 | ±5 % tolerance, SOT-23 package (3.0 mm × 1.4 mm), higher Rth(j-a) (~450 K/W), no AEC-Q101 qualification. | General-purpose industrial regulation only; unsuitable for automotive due to larger footprint and unqualified reliability. | Select only for cost-sensitive non-automotive designs where ±5 % tolerance and manual AOI suffice. |
| MMSZ5240B-TP | ±5 % tolerance, SOD-123 package (3.7 mm × 1.6 mm), 10 Ω typical ZZT, not qualified to AEC-Q101. | Limited to consumer or industrial power supplies; lacks side-wettable flanks and fails automotive thermal cycling requirements. | Use only when legacy SOD-123 footprint compatibility is mandatory and automotive qualification is not required. |
Compared with BZX84-C9V1,115 and MMSZ5240B-TP, PZU884LS-B9V1-QYL delivers tighter tolerance, smaller size, lower thermal resistance, and full AEC-Q101 compliance - making it the sole choice for next-generation automotive Zener regulation where space, reliability, and precision are co-constrained.

FAQ
What is the maximum continuous forward current for PZU884LS-B9V1-QYL?
The absolute maximum forward current is 200 mA per the limiting values table. However, this device is intended for reverse-bias Zener operation; forward conduction is limited to brief pulses (e.g., during power-up sequencing) and must remain below 0.9 V forward voltage at 10 mA to avoid thermal overstress.
Does PZU884LS-B9V1-QYL require a heatsink in standard PCB mounting?
No heatsink is required. With Rth(j-a) = 340 K/W on a single-sided FR4 PCB (70 μm Cu, tin-plated), the device dissipates up to 365 mW continuously at ambient temperatures ≤85 °C. Derating begins above 85 °C ambient per the thermal characteristics curve.
How does the side-wettable flank feature improve manufacturability?
Side-wettable flanks enable automated optical inspection (AOI) of solder fillet formation on both lateral edges of the DFN1006BD-2 package. This eliminates reliance on X-ray for solder joint validation, reducing test cost and cycle time in high-volume automotive SMT lines.
Is PZU884LS-B9V1-QYL compatible with lead-free reflow profiles?
Yes. The device is qualified for standard JEDEC J-STD-020 lead-free reflow profiles (peak temperature 260 °C, 60 seconds max). The SOD882BD package outline and solder land pattern in Figure 10 are optimized for IPC-7351-compliant stencil design and void-free solder joints.
