Product details
Overview
BZX884S-B30-QYL from Nexperia is a ±2 % tolerance Zener diode in a DFN1006BD-2 (SOD882BD) leadless SMD package, designed for precision voltage regulation at 30 V nominal breakdown voltage with 70 Ω typical differential resistance at IZ = 2 mA and −30 mV/K temperature coefficient. It delivers stable reference performance in automotive power supply monitoring and ECU biasing circuits.
For engineers reviewing the BZX884S-B30-QYL datasheet, BZX884S-B30-QYL pinout, BZX884S-B30-QYL application, or BZX884S-B30-QYL equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for automated optical inspection, 365 mW power rating on FR4, and 30 V ±2 % Zener voltage with low thermal drift in compact 1.0 mm × 0.6 mm footprint.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain a stable 30 V reference across load variations, with specified test current of 2 mA per the B-series tolerance grade. Its differential resistance of 70 Ω (typical) ensures minimal voltage shift under dynamic current changes.
Qualified to AEC-Q101, it supports operation from −55 °C to +150 °C ambient, with junction temperature limited to 150 °C and thermal resistance of 340 K/W (junction-to-ambient, FR4 PCB). The cathode-marked side-wettable flank enables reliable solder joint inspection in automotive assembly lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 29.4 V to 30.6 V at IZ = 2 mA - tight ±2 % tolerance enables accurate voltage clamping in safety-critical automotive sensors |
| Differential Resistance rdif | 70 Ω typical at IZ = 2 mA - low impedance maintains stable regulation under varying load currents |
| Temperature Coefficient SZ | −30 mV/K typical - predictable negative drift allows compensation in temperature-sensitive reference designs |
| Power Dissipation Ptot | 365 mW on FR4 PCB - sufficient headroom for transient overvoltage suppression in 12 V/24 V vehicle systems |
| Forward Voltage VF | 0.9 V max at IF = 10 mA - low conduction loss when used bidirectionally or in protection configurations |
| Reverse Current IR | 0.05 μA max at VR = 22.5 V - ultra-low leakage preserves battery life in always-on automotive modules |
| Package | DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm - ultra-small footprint with side-wettable flanks for AOI-compatible reflow assembly |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal leadless plastic package with side-wettable flanks, 0.65 mm pitch, and marking bar indicating cathode.
| 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; terminal geometry optimized for solder fillet formation on side-wettable flank |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HAST, and mechanical shock per JESD47 |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, reducing post-reflow defect escape |
| ±2 % Zener tolerance | Meets tight regulation requirements for engine control unit (ECU) reference rails and sensor excitation circuits |
| Ultra-small footprint | 1.0 mm × 0.6 mm body area saves >60 % board space vs. traditional SOD-323 Zeners in high-density ADAS modules |
| Low thermal resistance | 340 K/W junction-to-ambient enables operation up to 150 °C ambient in under-hood environments |
Applications
| Automotive Power Rail Monitoring | Engine Control Unit (ECU) Bias Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-C30-Q | ±5 % tolerance (28.0 V–32.0 V), higher 80 Ω rdif, +25 mV/K SZ | Acceptable for non-critical biasing where cost sensitivity outweighs precision | Select for cost-driven consumer electronics where AEC-Q101 is not required |
| MMSZ5262BT1G | ±5 % tolerance (28.5 V–31.5 V), SOD-123 package, 100 Ω rdif, no side-wettable flanks | Lacks AOI support and automotive qualification; suitable only for industrial PCBs with manual inspection | Choose only if legacy SOD-123 footprint must be retained and AEC-Q101 compliance is waived |
Compared with BZX884S-B30-QYL, the C30-Q offers lower cost but sacrifices regulation accuracy and thermal stability, while MMSZ5262BT1G lacks both automotive qualification and manufacturability features-making the B30-QYL optimal for new AEC-Q101-compliant designs requiring precision and process robustness.

FAQ
What is the maximum continuous reverse current the BZX884S-B30-QYL can sustain without degradation?
The device is rated for 200 mA maximum forward current, but as a Zener diode, its reverse operation is defined by power dissipation. At 30 V, sustained reverse current must remain ≤12.2 mA to stay within the 365 mW total power limit on FR4 PCB. Exceeding this risks thermal runaway and permanent parameter shift.
Does the side-wettable flank require special stencil design or reflow profile adjustments?
No special stencil is needed-the standard SOD882BD footprint (1.3 mm × 0.7 mm solder land, 0.4 mm paste opening) specified in Figure 11 supports full wetting. Reflow must follow JEDEC J-STD-020 moisture sensitivity level 1 profile; peak temperature 260 °C ensures proper solder flow to flanks without voiding.
How does the −30 mV/K temperature coefficient impact long-term reference stability in under-hood applications?
Over a −40 °C to +125 °C range, the coefficient causes a total drift of −4.95 V (−30 mV/K × 165 K), shifting VZ from ~31.2 V to ~26.25 V. This is fully characterized and repeatable, allowing system-level compensation in firmware or analog circuit design-no unmodeled instability occurs.
Can BZX884S-B30-QYL replace older BZX84-C30 in existing designs?
Yes, with layout adaptation: both regulate at ~30 V, but BZX884S-B30-QYL uses DFN1006BD-2 (1.0 mm × 0.6 mm) versus SOT-23 (3.0 mm × 1.4 mm). The smaller footprint requires pad redesign, yet delivers superior thermal performance (340 K/W vs. ~450 K/W) and AEC-Q101 compliance-justifying the change for new automotive releases.
