Product details
Overview
BZX884S-C11-QYL from Nexperia is a Zener voltage regulator diode in the BZX884S-Q series, designed for precision voltage reference and regulation in compact automotive and industrial circuits. It delivers a nominal 11 V breakdown voltage (VZ = 10.4–11.6 V at IZ = 5 mA), ±5 % tolerance, 365 mW power dissipation, and operates across −55 °C to +150 °C ambient range - qualified per AEC-Q101.
For engineers reviewing the BZX884S-C11-QYL datasheet, BZX884S-C11-QYL pinout, BZX884S-C11-QYL application, or BZX884S-C11-QYL equivalent, this device serves as a space-constrained, thermally robust Zener solution where stable low-current reference, overvoltage clamping, or biasing in sensor interfaces, power supply feedback, and automotive ECUs is required.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with a typical differential resistance of 50 Ω at 5 mA test current and a temperature coefficient of +5.4 mV/K - indicating positive thermal drift optimized for mid-range voltage references. Its junction-to-ambient thermal resistance is 340 K/W on standard FR4 PCB, limiting continuous power handling without heatsinking.
The device uses a planar epitaxial process and features side-wettable flanks (SWF) in the DFN1006BD-2 (SOD882BD) package, enabling reliable automated optical inspection (AOI) of solder joints. Cathode identification is marked by a visible bar on the top surface, aligning with Pin 1 per JEDEC MO-343AA outline.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (Nominal) | 11 V - precise reverse breakdown voltage at 5 mA, used for stable reference generation |
| VZ Tolerance | ±5 % - defines allowable deviation (10.4–11.6 V), suitable for non-critical regulation |
| Ptot | 365 mW - maximum continuous power dissipation on standard FR4 PCB, constraining IZ to ~33 mA at 11 V |
| IF max | 200 mA - peak forward current rating, supporting transient surge handling in clamp configurations |
| Tj max | 150 °C - maximum junction temperature, enabling operation in under-hood automotive environments |
| Rth(j-a) | 340 K/W - thermal resistance limiting self-heating; requires layout-aware copper area for sustained loads |
| Cd | 85 pF at 1 MHz / 0 V - low capacitance preserves high-frequency stability in feedback paths |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), ultra-small leadless plastic package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks and 0.65 mm pitch. Mounting requires reflow only; no through-hole or hand-soldering support.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Marked side) | Cathode (K) | Connected to regulated output node; reverse-bias anode-to-cathode voltage triggers Zener conduction |
| 2 | Anode (A) | Typically grounded or connected to lower-potential rail; completes reverse-bias path for regulation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder joint integrity on both sides of the terminal |
| Ultra-small footprint | 0.6 mm² board area saves space in dense layouts such as ADAS sensor modules and body control units |
| Wide VZ range coverage | Part of 37-value series spanning 2.4 V to 75 V, allowing single-package-family design reuse |
| Low leakage at low VR | Reverse current ≤ 0.1 μA at 8.8 V (0.8 × VZ) ensures minimal quiescent error in reference circuits |
Applications
| Automotive Sensor Biasing | Power Supply Feedback Clamp |
|---|---|
|
Use Scenario: Providing stable bias voltage to analog sensors (e.g., pressure, temperature) in engine control units. IC Role / Device Role / Timing Role: Zener reference source establishing fixed DC operating point for sensor excitation circuitry. Use Value: Maintains sensor accuracy across −40 °C to +125 °C ambient with <±0.5 % VZ shift over temperature due to predictable +5.4 mV/K coefficient. |
Use Scenario: Clamping feedback node in isolated flyback converter secondary-side regulation loop. IC Role / Device Role / Timing Role: Overvoltage protection element limiting optocoupler input voltage during load transients. Use Value: Fast response (<10 ns) and low dynamic impedance (50 Ω) prevent feedback loop instability while absorbing up to 365 mW surge energy. |
| Industrial I/O Protection | Low-Power Reference Generator |
|
Use Scenario: Protecting microcontroller GPIO pins against ESD and induced surges on 24 V fieldbus lines. IC Role / Device Role / Timing Role: Bidirectional transient suppressor configured in back-to-back arrangement with another Zener. Use Value: Withstand 200 mA peak forward current and 150 °C junction temperature, surviving repeated 8 kV contact ESD events per IEC 61000-4-2. |
Use Scenario: Generating precise 11 V reference for ADC reference buffer in battery-powered data loggers. IC Role / Device Role / Timing Role: Low-noise, low-drift voltage source feeding op-amp-based reference divider network. Use Value: 85 pF capacitance minimizes high-frequency noise coupling; 0.1 μA IR at 8.8 V ensures <1 ppm measurement error contribution at 10-bit resolution. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B11-Q | ±2 % tolerance (10.8–11.2 V), higher cost, tighter rdif (50 Ω vs. 50 Ω typ) | Better stability in precision reference designs requiring <±0.2 % total error budget | Select when VZ accuracy dominates over cost and board area constraints |
| MMSZ5240B-TP | Same 11 V nominal, SOD-123 package (2.7 × 1.6 mm), 500 mW Ptot, no AEC-Q101 | Higher power handling but larger footprint; unsuitable for automotive production | Choose for industrial prototypes needing marginally higher surge capability without SWF AOI requirement |
Compared with BZX884S-C11-QYL, the BZX884S-B11-Q offers tighter tolerance for metrology-grade references, while MMSZ5240B-TP trades automotive qualification and miniaturization for higher power and legacy package compatibility - making the C11-QYL optimal for volume automotive PCBs where space, reliability, and AOI are critical.

FAQ
Is BZX884S-C11-QYL suitable for use in automotive under-hood applications?
Yes - it is fully qualified to AEC-Q101 standards and rated for operation from −55 °C to +150 °C ambient temperature. Its DFN1006BD-2 package with side-wettable flanks supports automated optical inspection, and its 150 °C maximum junction temperature enables deployment in proximity to engines and power converters without derating.
What is the meaning of the 'C' prefix in BZX884S-C11-QYL?
The 'C' denotes the ±5 % tolerance grade per the BZX884S-Q series marking scheme - distinguishing it from the 'B' grade (±2 %). For BZX884S-C11-QYL, this corresponds to a guaranteed VZ range of 10.4 V to 11.6 V at 5 mA test current, as confirmed in Table 8 of the datasheet.
Can BZX884S-C11-QYL be used in forward-bias applications?
It is rated for 200 mA peak forward current and exhibits a typical forward voltage of ≤0.9 V at 10 mA, making it usable as a low-drop rectifier or ESD clamp in bidirectional configurations. However, its primary design intent and characterization focus remain reverse-bias Zener regulation - forward conduction parameters are secondary specifications.
How does the side-wettable flank (SWF) feature impact PCB assembly?
SWF enables reliable solder joint inspection via automated optical inspection (AOI) systems that detect wetting on both vertical sidewalls of the terminals. This eliminates hidden voids or insufficient fillets common in standard DFN packages, improving first-pass yield in high-reliability automotive manufacturing without requiring X-ray inspection.
