Product details
Overview
BZX884S-C6V8-QYL from Nexperia is a Zener voltage regulator diode in the BZX884S-Q series, designed for precision voltage reference and overvoltage protection in compact automotive and industrial circuits. It delivers a nominal 6.8 V breakdown voltage with ±5 % tolerance, 30 Ω typical differential resistance at 5 mA, and operates up to 150 °C junction temperature in the ultra-small DFN1006BD-2 (SOD882BD) package.
For engineers reviewing the BZX884S-C6V8-QYL datasheet, BZX884S-C6V8-QYL pinout, BZX884S-C6V8-QYL application, or BZX884S-C6V8-QYL equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for automated optical inspection, low 120 pF capacitance at 1 MHz, and thermal resistance of 340 K/W on FR4 PCB.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain stable voltage across load variations and supply fluctuations. Its 6.8 V nominal Zener voltage is specified at 5 mA test current, with a positive temperature coefficient of +1.2 mV/K enabling predictable drift compensation in temperature-sensitive references.
The device uses silicon planar technology with controlled doping to achieve tight voltage distribution and low leakage: reverse current remains ≤2 μA at 5.44 V (80 % of VZ), and forward voltage is ≤0.9 V at 10 mA, supporting bidirectional clamping and polarity-aware circuit design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.4 V to 7.2 V at IZ = 5 mA - defines regulated output range under standard bias |
| Differential Resistance (rdif) | 30 Ω typical at IZ = 5 mA - determines regulation stiffness against load current changes |
| Temperature Coefficient (SZ) | +1.2 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius for thermal design margining |
| Reverse Current (IR) | ≤2 μA at VR = 5.44 V - ensures minimal leakage power loss in standby or high-impedance nodes |
| Power Dissipation (Ptot) | 365 mW on FR4 PCB - sets maximum continuous DC or pulsed power handling in standard layout |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables operation in under-hood automotive and industrial environments |
| Package | DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm - supports high-density routing and AOI-compatible reflow |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a leadless, surface-mount plastic package with side-wettable flanks for solder joint inspection. Dimensions: 1.0 mm × 0.6 mm × 0.47 mm body, 0.65 mm pitch, cathode marked by a visible bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity must be observed for correct Zener conduction |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, reducing assembly QA cost |
| Ultra-small footprint | 0.6 mm² board area saves space in battery management, ADAS sensor modules, and ECU power rails |
| Low capacitance | 120 pF at 1 MHz - minimizes signal distortion in high-frequency clamp or reference applications |
| Two tolerance options | ±2 % (B-series) and ±5 % (C-series) - allows cost/performance trade-off in volume production |
Applications
| Automotive ECU Power Rail Clamping | Industrial Sensor Reference Voltage |

Use Scenario: Protects microcontroller I/O and analog front-end inputs from transients on 12 V vehicle power bus. IC Role / Device Role / Timing Role: Zener acts as shunt overvoltage clamp, diverting surge current above 6.8 V to ground before downstream IC damage occurs. Use Value: AEC-Q101 rating ensures survival across −40 °C to +125 °C ambient, while 365 mW Ptot handles ISO 7637-2 pulse 5a surges without derating. |
Use Scenario: Provides stable 6.8 V reference for 12-bit ADC in programmable logic controller (PLC) analog input modules. IC Role / Device Role / Timing Role: Functions as passive voltage reference source, replacing larger TL431-based circuits where size and cost are critical. Use Value: ±5 % tolerance and +1.2 mV/K TC allow direct use in 0–70 °C industrial environments without active compensation, reducing BOM count. |
| USB-C Port Overvoltage Protection | IoT Node Battery Voltage Monitor |
|
Use Scenario: Guards USB-C power delivery interface against accidental 20 V adapter misconnection. IC Role / Device Role / Timing Role: Placed between VBUS and ground to clamp transient excursions beyond 6.8 V, limiting stress on USB-PD controller. Use Value: 120 pF capacitance avoids signal integrity degradation on CC and SBU lines, preserving USB 2.0 data timing margins. |
Use Scenario: Monitors lithium-thionyl chloride (LiSOCl₂) primary cell voltage decay in remote asset trackers. IC Role / Device Role / Timing Role: Used in comparator-based threshold detector, where Zener voltage defines low-battery trip point at ~6.8 V. Use Value: ≤2 μA IR at 5.44 V ensures <1 nW standby power draw, extending 10-year battery life without measurable impact. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B6V8-Q | Nominal 6.8 V with ±2 % tolerance (vs. ±5 %); 40 Ω rdif vs. 30 Ω typical | Tighter regulation needed in precision reference designs; higher rdif increases output impedance | Select when absolute voltage accuracy > stability under varying load current |
| MMSZ4687T1G | 6.8 V, ±5 %, SOD-123 package (2.7 mm × 1.6 mm), 500 mW Ptot, 150 pF Cd | Larger footprint but higher power handling; no side-wettable flanks for AOI | Choose for non-automotive industrial use where board space is less constrained and AOI not required |
Compared with BZX884S-C6V8-QYL, the BZX884S-B6V8-Q offers tighter voltage control at the expense of slightly higher dynamic impedance, while the MMSZ4687T1G trades miniaturization and AOI capability for greater power margin and legacy package compatibility.

FAQ
What is the maximum continuous reverse current this Zener can handle without degradation?
The BZX884S-C6V8-QYL has an absolute maximum forward current of 200 mA, but as a Zener diode it is operated in reverse breakdown. Its limiting reverse current is defined by power dissipation: at 6.8 V, continuous operation is limited to ≈53.7 mA (365 mW ÷ 6.8 V) on a standard FR4 PCB. Exceeding this risks thermal runaway and permanent parameter shift.
Does the side-wettable flank design require special stencil or reflow profile adjustments?
No special stencil or reflow profile is required. The side-wettable flanks are compatible with standard Type 3 or Type 4 solder paste, 0.1 mm laser-cut stencils, and IPC/JEDEC J-STD-020-compliant reflow profiles for DFN packages. The feature enables post-reflow AOI verification without altering process parameters.
How does the +1.2 mV/K temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
Over that 165 K range, the total voltage drift is approximately +198 mV (165 × 1.2 mV/K). At 6.8 V nominal, this represents a +2.9 % shift - within the ±5 % tolerance band. For tighter accuracy, designers may pair it with a negative-TC component or use it in ambient-stabilized zones where ΔT is limited to <50 K.
Can this Zener be used in series or parallel configurations for higher voltage or current handling?
Series connection is viable for higher voltage references (e.g., two 6.8 V devices yield ~13.6 V), but mismatched temperature coefficients cause unequal voltage sharing. Parallel use is strongly discouraged due to thermal runaway risk - slight VZ variation leads to current hogging and localized overheating, even with ballast resistors.
