Product details
Overview
BZX884S-C10-QYL from Nexperia is a Zener voltage regulator diode in the BZX884S-Q series, designed for precision voltage reference and overvoltage protection in compact SMD circuits. It provides a nominal 10 V Zener voltage with ±5 % tolerance, 50 Ω typical differential resistance at 5 mA, and operates up to 150 °C junction temperature. It is qualified to AEC-Q101 and used in automotive power rail clamping and sensor biasing.
For engineers reviewing the BZX884S-C10-QYL datasheet, BZX884S-C10-QYL pinout, BZX884S-C10-QYL application, or BZX884S-C10-QYL equivalent, this page delivers verified package dimensions, thermal resistance (340 K/W), forward voltage (≤0.9 V @ 10 mA), total power dissipation (365 mW), and side-wettable flank solderability - all critical for high-reliability PCB layout and automotive-grade qualification.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load and temperature conditions. Its 10 V nominal Zener voltage is specified at 5 mA test current, with a temperature coefficient of +4.5 mV/K and reverse current ≤0.2 μA at 7.6 V.
The device uses a planar epitaxial process and is housed in a leadless DFN1006BD-2 (SOD882BD) package with side-wettable flanks for automated optical inspection (AOI) of solder joints. It supports reflow-only assembly and meets automotive reliability requirements per AEC-Q101.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.4 V to 10.6 V @ IZ = 5 mA - defines clamping threshold for 12 V rail protection |
| Differential Resistance (rdif) | 50 Ω typ @ IZ = 5 mA - determines voltage regulation stiffness under load variation |
| Forward Voltage (VF) | ≤0.9 V @ IF = 10 mA - ensures low-loss conduction during forward-biased transient events |
| Total Power Dissipation (Ptot) | 365 mW on FR4 PCB - sets maximum continuous power handling without heatsinking |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables operation in under-hood automotive environments |
| Thermal Resistance (Rth(j-a)) | 340 K/W - quantifies self-heating rise per watt on standard PCB layout |
| Reverse Current (IR) | ≤0.2 μA @ VR = 7.6 V - ensures minimal leakage before breakdown activation |
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 for AOI-compatible reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node; marking bar identifies this terminal for correct orientation |
| 2 | Anode (A) | Connected to lower-potential node (e.g., ground or return path); reverse-biased during regulation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics |
| Side-wettable flanks (SWF) | Enables automated optical inspection of solder joint integrity on both sides of the pad |
| ±5 % Zener voltage tolerance | Supports cost-sensitive designs where tighter tolerance is not required for clamping function |
| Low thermal resistance packaging | 340 K/W allows sustained 365 mW dissipation without derating on standard FR4 |
| Wide operating temperature range | −55 °C to +150 °C ambient enables use in extreme under-hood and industrial environments |
Applications
| Automotive ECU Power Rail Clamping | Industrial Sensor Bias Reference |
|---|---|
Use Scenario: Protects microcontroller I/O pins and analog front-ends from load-dump transients on 12 V vehicle power systems. IC Role / Device Role / Timing Role: Zener diode acting as shunt voltage clamp, conducting excess energy to ground when rail exceeds 10.6 V. Use Value: Prevents latch-up or damage to downstream ICs by limiting peak voltage to ≤10.6 V with <0.2 μA leakage below 7.6 V. |
Use Scenario: Provides stable 10 V reference for precision RTD or thermistor signal conditioning circuits. IC Role / Device Role / Timing Role: Passive voltage reference source with 50 Ω dynamic impedance ensuring minimal drift under varying sensor bridge currents. Use Value: Enables <±1 % reference stability over −40 °C to +125 °C due to +4.5 mV/K temperature coefficient and low rdif. |
| USB Port Overvoltage Protection | Programmable Logic Controller (PLC) Input Protection |
Use Scenario: Safeguards USB 5 V data lines against ESD and accidental 12 V misconnection in docking stations. IC Role / Device Role / Timing Role: Fast-acting shunt limiter placed between VBUS and ground, triggered within nanoseconds of overvoltage event. Use Value: Limits transient voltage to ≤10.6 V while dissipating up to 365 mW, compatible with IEC 61000-4-2 Level 4 ESD immunity. |
Use Scenario: Shields 24 V digital input channels in industrial PLC modules from field-wiring faults and surge coupling. IC Role / Device Role / Timing Role: Primary clamping element in multi-stage protection network, absorbing initial surge energy before TVS activation. Use Value: Withstands repeated 100 ms overvoltage events up to 15 V due to 150 °C Tj rating and robust DFN package construction. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B10-Q | ±2 % tolerance (9.8 V–10.2 V) vs. ±5 % (9.4 V–10.6 V); 50 Ω rdif same | Higher precision needed for reference circuits; tighter thermal drift control | Select when voltage accuracy > regulation robustness; requires tighter layout control |
| MMSZ4689-HE3-08 | 10 V nominal, ±5 %, but SOD-123 package (1.8 mm × 1.4 mm); 300 mW Ptot | Larger footprint, lower power rating, no side-wettable flanks | Choose only if legacy SOD-123 compatibility is mandatory; sacrifices AOI capability and thermal performance |
Compared with BZX884S-C10-QYL, the BZX884S-B10-Q offers tighter voltage control for metrology-grade references, while MMSZ4689-HE3-08 trades miniaturization and automotive qualification for legacy package compatibility and reduced thermal margin.

FAQ
What is the maximum continuous reverse current the BZX884S-C10-QYL can handle before breakdown?
The device is rated for a maximum forward current of 200 mA per Absolute Maximum Ratings, but its Zener operation relies on controlled reverse current. At 5 mA test current, it maintains 10 V regulation; sustained reverse current beyond 100 mA risks exceeding 365 mW power limit and thermal runaway unless actively cooled.
Does the side-wettable flank design require special stencil or reflow profile adjustments?
No special stencil is required - standard 0.12 mm thickness with 0.3 mm aperture works. Reflow must follow JEDEC J-STD-020 profile for MSL1; peak temperature 260 °C max. Side-wettable flanks enable post-reflow AOI verification without X-ray, eliminating need for profile deviation.
How does the +4.5 mV/K temperature coefficient affect regulation accuracy over temperature?
Over a −40 °C to +125 °C range (165 K delta), the coefficient causes ~743 mV total drift (165 × 4.5). Combined with ±5 % initial tolerance (±0.5 V), worst-case regulation spans 9.4 V to 11.34 V - acceptable for clamping but not precision reference use without compensation.
Can BZX884S-C10-QYL replace older BZX84-C10 in existing designs?
Yes, with caveats: identical 10 V rating and SOD-323 pinout compatibility, but BZX884S-C10-QYL uses smaller DFN1006BD-2 (1.0 × 0.6 mm) vs. SOD-323 (1.7 × 1.3 mm). PCB land pattern must be updated; thermal performance improves (+365 mW vs. +300 mW), and AEC-Q101 qualification adds automotive suitability.
