Product details
Overview
BZX884S-C22-QYL from Nexperia is a ±5 % tolerance Zener diode in a DFN1006BD-2 (SOD882BD) leadless SMD package, designed for precision voltage regulation at 22 V nominal breakdown voltage with 20.8 V to 23.3 V operating range, 60 Ω typical differential resistance at 5 mA, and AEC-Q101 qualification for automotive power rail stabilization.
For engineers reviewing the BZX884S-C22-QYL datasheet, BZX884S-C22-QYL pinout, BZX884S-C22-QYL application, or BZX884S-C22-QYL equivalent, this device serves as a compact, side-wettable-flank-compatible voltage reference in space-constrained DC-DC feedback paths, ECU overvoltage clamping, and low-power sensor biasing where thermal stability and automotive-grade reliability are required.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with a specified 22 V nominal Zener voltage (VZ) at IZ = 5 mA, exhibiting a temperature coefficient of +15.4 mV/K and reverse current ≤0.05 μA at 17.6 V. Its junction-to-ambient thermal resistance is 340 K/W on standard FR4 PCB.
The device uses silicon planar epitaxial construction with side-wettable flanks for automated optical solder-joint inspection, and achieves stable regulation under pulse conditions (tp ≤ 300 μs, duty cycle ≤ 0.02), supporting transient-suppression roles in 12 V/24 V automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 20.8 V to 23.3 V at IZ = 5 mA - defines regulated output voltage window for feedback or clamp circuits |
| Differential Resistance (rdif) | 60 Ω typ. at IZ = 5 mA - determines load regulation error and dynamic impedance in shunt regulator loops |
| Temperature Coefficient (SZ) | +15.4 mV/K - quantifies VZ drift per degree Celsius, critical for temperature-stable references |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - enables low-loss forward conduction during polarity-reversal protection |
| Total Power Dissipation (Ptot) | 365 mW on FR4 PCB - sets maximum continuous power handling without derating in standard layout |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress-test requirements including HTOL, TC, and ESD |
Pinout & Package
DFN1006BD-2 (SOD882BD) ultra-small leadless plastic package: 1.0 mm × 0.6 mm × 0.47 mm body, 0.65 mm pitch, side-wettable flanks for solder-joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for orientation during placement |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, reducing manufacturing defect escape |
| ±5 % VZ tolerance | Supports cost-sensitive designs where tighter tolerance is unnecessary, balancing accuracy and BOM cost |
| AEC-Q101 qualification | Validates reliability for automotive applications including engine control units and ADAS power domains |
| Ultra-small footprint (1.0 × 0.6 mm) | Reduces PCB area by >50 % vs. SOD-323, enabling high-density routing in compact ECUs and sensors |
| Low reverse leakage (≤0.05 μA at 17.6 V) | Minimizes quiescent current draw in always-on battery-backed circuits such as CAN wake-up receivers |
Applications
| Automotive ECU Voltage Clamp | Industrial Sensor 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-B22-Q | ±2 % VZ tolerance (21.6–22.4 V), higher rdif (60 Ω vs. 60 Ω typ.), same package | Preferred where tighter regulation is needed in precision feedback loops | Select when VZ stability across temperature and current is prioritized over cost |
| MMSZ5247ET1G | ±5 % VZ (21.6–23.4 V), SOD-123 package (2.7 × 1.6 mm), 500 mW Ptot, no AEC-Q101 | Suitable for industrial non-automotive use with higher power margin but larger footprint | Choose when board space is less constrained and automotive qualification is not required |
Compared with BZX884S-C22-QYL, the BZX884S-B22-Q offers tighter tolerance at identical thermal performance, while MMSZ5247ET1G trades automotive qualification and miniaturization for higher power handling and broader industry availability.

FAQ
What is the maximum reverse voltage before breakdown for BZX884S-C22-QYL?
The nominal Zener voltage is 22 V, with a guaranteed breakdown range of 20.8 V to 23.3 V at 5 mA test current. Below 20.8 V, reverse leakage remains ≤0.05 μA at 17.6 V; full conduction begins within this window and stabilizes above 23.3 V under specified thermal conditions.
Can BZX884S-C22-QYL be used in place of a 22 V Zener in an existing SOD-323 design?
No - BZX884S-C22-QYL uses the DFN1006BD-2 (SOD882BD) package (1.0 × 0.6 mm), which is physically incompatible with SOD-323 footprints (1.7 × 1.3 mm). A redesign of the PCB land pattern and stencil is required to accommodate side-wettable flanks and 0.65 mm pitch.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
With a +15.4 mV/K temperature coefficient, VZ increases by approximately 2.5 V across that 165 K range. At 125 °C, VZ reaches ~24.5 V - a deviation of +11.4 % from nominal. This must be accounted for in feedback divider design or compensated via external circuitry.
Is reflow soldering the only recommended assembly method?
Yes - Nexperia specifies reflow soldering as the sole qualified process for BZX884S-C22-QYL. Wave soldering and hand soldering are not supported due to thermal sensitivity and the need to preserve side-wettable flank integrity for AOI compatibility.
