Product details
Overview
PZU884LS-B8V2-QYL from Nexperia is an AEC-Q101-qualified Zener voltage regulator diode in the ultra-small DFN1006BD-2 (SOD882BD) package, designed for precision voltage reference and clamping in automotive power rails. It delivers a nominal 8.2 V Zener voltage with ±2 % tolerance, 250 Ω typical differential resistance at IZ = 5 mA, and operates up to 150 °C junction temperature.
For engineers reviewing the PZU884LS-B8V2-QYL datasheet, PZU884LS-B8V2-QYL pinout, PZU884LS-B8V2-QYL application, or PZU884LS-B8V2-QYL equivalent, this device supports low-leakage, hard-knee regulation in space-constrained automotive ECUs, ADAS sensor supplies, and infotainment voltage supervisors where side-wettable flanks enable reliable AOI inspection and reflow soldering.
Technical Context
This Zener diode belongs to the PZU884LS-Q series' "B" tolerance group (±2 %), optimized for low dynamic impedance and minimal leakage current-critical for stable reference generation under light-load conditions. Its hard breakdown knee ensures predictable turn-on behavior during transient suppression.
The DFN1006BD-2 package features side-wettable flanks for automated optical inspection of solder joints and supports high-density PCB layouts. Thermal resistance from junction to ambient is 340 K/W on standard FR4, enabling operation at full 365 mW dissipation only with adequate copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.2 V nominal, ±2 % tolerance - ensures tight regulation accuracy for 8 V rail supervision and feedback sensing |
| Differential Resistance (rdif) | 250 Ω typ. at IZ = 5 mA - maintains stable output voltage under small load variations |
| Reverse Current (IR) | 0.5 μA max. at VR = 6.6 V - enables low-power standby mode without excessive quiescent drain |

| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder fillets without X-ray, improving manufacturing yield |
| Hard breakdown knee | Sharp, well-defined Zener turn-on reduces regulation hysteresis in feedback loops and reference circuits |
| Low leakage current | <0.5 μA at 80 % VZ minimizes error in high-impedance bias networks and battery-backed circuits |
| E24 voltage range support | Part of 2.4 V–51 V family with standardized values simplifies BOM consolidation across vehicle platforms |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C8V2,215 | ±5 % tolerance, SOT23 package (3.0 mm × 1.4 mm), higher rdif (~400 Ω), no AEC-Q101 qualification | Suitable for cost-sensitive consumer-grade 8.2 V references but lacks automotive reliability and thermal performance | Select only for non-automotive designs where board space and qualification are not constraints |
| MMSZ5236B-TP | ±5 % tolerance, SOD-123 package (2.7 mm × 1.6 mm), 350 mW Ptot, no side-wettable flanks | Acceptable for industrial power monitoring but lacks AOI compatibility and fails AEC-Q101 stress tests | Prefer only when legacy footprint compatibility outweighs manufacturability and automotive compliance needs |
Compared with BZX84-C8V2,215 and MMSZ5236B-TP, the PZU884LS-B8V2-QYL offers tighter tolerance, smaller footprint, AEC-Q101 validation, and side-wettable flanks-making it the sole choice for new automotive designs requiring production-ready, inspectable, and thermally robust Zener regulation.

FAQ
What is the maximum continuous forward current rating for PZU884LS-B8V2-QYL?
The device is a Zener diode intended for reverse-bias operation; its absolute maximum forward current is 200 mA per limiting values table. However, forward conduction is not a functional mode-forward voltage is specified only for characterization (0.9 V at 10 mA). Continuous forward bias degrades long-term stability and is not recommended in circuit design.
Does PZU884LS-B8V2-QYL require a heatsink for 365 mW operation?
No external heatsink is required, but thermal performance depends entirely on PCB layout. The 365 mW rating assumes mounting on FR4 with single-sided 70 μm copper and standard footprint per datasheet condition. Doubling copper area or adding thermal vias can improve power handling; derating is necessary on compact or thermally isolated boards.
How does the "B" suffix in PZU884LS-B8V2-QYL differ from "C" variants?
The "B" suffix denotes ±2 % Zener voltage tolerance and optimized low-leakage, hard-knee characteristics for precision regulation. "C" variants offer approximately ±5 % tolerance and slightly higher leakage-intentionally tuned for fast switching and noise reduction per AN90031. For 8.2 V reference accuracy, "B" is mandatory.
Can PZU884LS-B8V2-QYL be used in parallel for higher power handling?
Parallel connection is not recommended due to mismatch in Zener voltage and dynamic resistance, which causes current imbalance and thermal runaway. For higher power, use a single higher-rated device or implement active regulation. The datasheet specifies only individual device ratings and does not characterize parallel operation.
