Product details
Overview
BZX884S-B10-QYL from Nexperia is a 10 V ±2 % tolerance Zener diode in a leadless DFN1006BD-2 (SOD882BD) package, designed for precision voltage regulation and reference functions in space-constrained automotive and industrial circuits. It delivers 365 mW total power dissipation at 25 °C, exhibits 90 Ω typical differential resistance at IZ = 5 mA, and features side-wettable flanks for reliable automated optical inspection (AOI) during reflow soldering.
For engineers reviewing the BZX884S-B10-QYL datasheet, BZX884S-B10-QYL pinout, BZX884S-B10-QYL application, or BZX884S-B10-QYL equivalent, this device is selected for low-profile, AEC-Q101-qualified voltage clamping, overvoltage protection, and stable biasing in DC-DC feedback networks where thermal stability and board area efficiency are critical.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 10.0 V (B-series, ±2 % tolerance), specified at IZ = 5 mA. Its temperature coefficient is +4.5 mV/K at IZ = 5 mA, enabling predictable drift compensation in temperature-sensitive references.
The device uses a planar epitaxial silicon process and is qualified to AEC-Q101, supporting operation from −55 °C to +150 °C ambient. Thermal resistance from junction-to-ambient is 340 K/W on standard FR4 PCB, defining its derating behavior under sustained power dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.80 V to 10.20 V at IZ = 5 mA - tight ±2 % tolerance enables accurate voltage setting in feedback loops and reference dividers |
| Differential Resistance (rdif) | 50 Ω typical at IZ = 5 mA - low impedance ensures stable regulation under varying load current |
| Temperature Coefficient (SZ) | +4.5 mV/K at IZ = 5 mA - positive drift allows predictable compensation when paired with negative-coefficient components |
| Max Power Dissipation (Ptot) | 365 mW at Tamb = 25 °C on FR4 - defines safe continuous operating envelope before thermal derating begins |
| Reverse Current (IR) | ≤0.2 μA at VR = 7.0 V - ultra-low leakage preserves accuracy in high-impedance bias networks |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - supports use as forward-biased clamp or ESD protection element in dual-role designs |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables deployment in under-hood automotive modules and industrial motor drives |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), leadless surface-mount, 1.0 mm × 0.6 mm × 0.47 mm body, side-wettable flanks, 0.65 mm pitch. Cathode identified by marking bar on 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 clamping |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47 |
| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder joint quality without X-ray, reducing manufacturing defect escape |
| Ultra-small footprint | 0.6 mm² board area - ideal for wearables, ADAS sensors, and multi-rail PMICs where PCB real estate is constrained |
| ±2 % VZ tolerance | Reduces need for post-assembly trimming or external calibration in precision reference applications |
| Low thermal resistance packaging | 340 K/W junction-to-ambient on FR4 - supports higher sustained power than comparable SOD-323 devices |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-C10-Q | ±5 % tolerance (9.4 V–10.6 V), higher rdif (~150 Ω), +8.0 mV/K tempco | Acceptable for non-critical biasing but unsuitable for precision feedback or metrology | Select when cost sensitivity outweighs voltage accuracy and thermal stability requirements |
| MMSZ4689-TP | 10 V ±5 %, SOD-123 package (2.7 mm × 1.6 mm), Ptot = 500 mW, rdif = 150 Ω | Larger footprint and lower density; better for high-power, non-automotive applications | Choose when higher power handling is needed and board space permits larger package |
Compared with BZX884S-B10-QYL, the C10-Q offers lower cost but sacrifices regulation accuracy and thermal predictability; the MMSZ4689-TP trades miniaturization for higher power capacity and lacks AEC-Q101 qualification, making it suitable only for commercial-grade systems.

FAQ
What is the maximum reverse current at 7 V for BZX884S-B10-QYL?
The maximum reverse current (IR) is 0.2 μA at VR = 7.0 V and Tj = 25 °C, as specified in Table 8 of the datasheet. This ultra-low leakage ensures minimal loading on high-impedance reference nodes and preserves accuracy in precision divider networks.
Can BZX884S-B10-QYL be used in parallel for higher power handling?
No - Zener diodes exhibit manufacturing variations in VZ and dynamic resistance, causing current imbalance and thermal runaway when paralleled. For higher power, select a single higher-rated device such as the BZX884S-B10-QYL's 500 mW counterpart in SOD-123, or implement active current-sharing circuitry.
Is the cathode marking visible under standard AOI systems?
Yes - the cathode is indicated by a laser-marked bar on the top surface, and the side-wettable flanks enable full solder joint inspection using standard 2D AOI systems without requiring X-ray. The DFN1006BD-2 package was explicitly designed for compatibility with automotive-grade automated assembly verification.
How does the +4.5 mV/K temperature coefficient affect long-term reference stability?
The +4.5 mV/K coefficient means VZ increases by ~0.45 V over a 100 °C rise (e.g., from 25 °C to 125 °C). In precision applications, this drift is compensated by pairing with negative-TC resistors or using it in ratiometric configurations where relative stability matters more than absolute value.
