Product details
Overview
BZX8850S-B5V6-QYL from Nexperia is a low-current Zener voltage regulator diode in the BZX8850S-Q series, designed for precision voltage reference and regulation in space-constrained, low-power circuits. It delivers a nominal 5.6 V Zener voltage at 50 µA test current, with ±2 % tolerance (B-series), 400 Ω dynamic resistance at 5 mA, and 2.0 µA maximum reverse leakage at 4.0 V, enabling stable biasing in portable battery-powered sensors and automotive microcontroller I/O protection.
For engineers reviewing the BZX8850S-B5V6-QYL datasheet, BZX8850S-B5V6-QYL pinout, BZX8850S-B5V6-QYL application, or BZX8850S-B5V6-QYL equivalent, this device is selected for ultra-low-current regulation (50 µA test point), AEC-Q101-qualified operation in automotive ECUs, side-wettable flank solderability on DFN1006BD-2, and optimized noise performance via intentional leakage tuning per AN90031.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified knee at 50 µA, making it suitable for low-bias applications where traditional 5 mA Zeners draw excessive quiescent current. Its differential resistance of 400 Ω at 5 mA ensures predictable regulation slope under light load variation.
The device features an intentionally elevated leakage current profile (per AN90031) to improve switching speed and reduce high-frequency noise-distinct from standard Zeners-and is qualified to AEC-Q101 for junction temperatures up to 150 °C and ambient ranges from −55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.49 V to 5.71 V at IZ = 50 µA - tight ±2 % tolerance enables accurate reference without trimming in low-power sensor signal chains. |
| Differential Resistance (rdiff) | 400 Ω max at IZ = 5 mA - defines regulation stiffness; lower than C-series (500 Ω), supporting stable output under small load shifts. |
| Reverse Leakage (IR) | 2.0 µA max at VR = 4.0 V - intentionally elevated vs. legacy Zeners to suppress noise and accelerate turn-off in transient suppression. |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - supports use as clamping diode in bidirectional I/O protection with minimal forward drop penalty. |
| Total Power Dissipation (Ptot) | 365 mW at Tamb ≤ 25 °C on FR4 PCB - limits thermal rise in ultra-small DFN1006BD-2 package (1.0 × 0.6 mm). |
| Junction Temperature (Tj) | −55 °C to +150 °C - validated for under-hood automotive environments per AEC-Q101 stress testing. |
| Package Thermal Resistance (Rth(j-a)) | 340 K/W in free air - confirms suitability only for low-duty-cycle or pulsed regulation; requires layout-aware copper pour for sustained dissipation. |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), ultra-small leadless surface-mount plastic package with side-wettable flanks (SWF), 0.65 mm pitch, 1.0 mm × 0.6 mm × 0.47 mm body height. Cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity-sensitive connection-reverse bias required for Zener operation. |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms current path during reverse breakdown conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Low-test-current regulation | Specified at 50 µA - reduces standby current in always-on battery circuits (e.g., CAN wake-up monitors) by >95 % vs. 5 mA Zeners. |
| AEC-Q101 qualification | Qualified for automotive applications - meets stress tests for temperature cycling, HTRB, ESD, and mechanical shock per discrete semiconductor standard. |
| Side-wettable flanks (SWF) | Enables automated optical solder-joint inspection (AOI) on bottom terminals - critical for high-reliability automotive PCB assembly. |
| Optimized leakage profile | Intentional 2.0 µA IR at 4.0 V (vs. <0.1 µA in standard Zeners) - improves high-frequency noise rejection and switching transients per AN90031. |
| Tight voltage tolerance | ±2 % (B-series) - eliminates need for post-solder calibration in precision voltage references for ADC bias or op-amp feedback networks. |
Applications
| Automotive Body Control Module (BCM) Voltage Clamp | Portable Gas Sensor Bias Reference |
|---|---|
|
Use Scenario: Clamping LIN bus I/O pins against load-dump transients in door module ECUs. IC Role / Device Role / Timing Role: Zener clamp placed between LIN transceiver VIO and ground, conducting only during overvoltage events ≥5.6 V. Use Value: 2.0 µA leakage minimizes DC loading on 3.3 V LDO supplying transceiver; SWF package ensures AOI-verified solder joints for zero-defect automotive production. |
Use Scenario: Providing stable 5.6 V bias to electrochemical gas sensor heater elements in battery-operated CO detectors. IC Role / Device Role / Timing Role: Low-current Zener reference regulating heater supply via series resistor, operating continuously at 50 µA. Use Value: ±2 % VZ tolerance maintains heater temperature accuracy within ±1.5 °C; 365 mW Ptot allows safe 100 % duty cycle at ambient ≤25 °C. |
| Industrial PLC Analog Input Protection | Medical Wearable ECG Front-End Reference |
|
Use Scenario: Protecting 24 V analog input channels from field-wiring faults in DIN-rail mounted programmable logic controllers. IC Role / Device Role / Timing Role: Reverse-biased Zener shunting input to ground when fault voltage exceeds 5.6 V, diverting surge energy before op-amp input stage. Use Value: 400 Ω rdiff ensures clamping voltage stays below 6.2 V at 1 mA surge, preserving downstream amplifier integrity without crowbar action. |
Use Scenario: Generating precise 5.6 V reference for instrumentation amplifier gain-setting resistors in single-supply ECG front-end ASICs. IC Role / Device Role / Timing Role: Passive voltage reference stabilizing bias network for ultra-low-noise amplifiers sampling sub-mV cardiac signals. Use Value: Intentional leakage profile suppresses 1/f noise in reference path; DFN1006BD-2 footprint saves >0.5 mm² board area in compact wearable form factors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8850S-C5V6-Q | ±5 % tolerance (C-series), 500 Ω rdiff, 3.7 µA IR at 4.0 V - higher leakage, looser voltage spec. | Acceptable where cost sensitivity outweighs precision; not recommended for ADC references or low-leakage bias networks. | Select only if system-level calibration compensates for wider VZ spread and higher noise floor. |
| MMSZ5232BS-7-F | Same 5.6 V nominal, SOD-323 package (1.7 × 1.3 mm), 1000 Ω rdiff, 5 µA IR - larger footprint, higher dynamic impedance, no AEC-Q101 rating. | Suitable for non-automotive consumer boards; lacks SWF and automotive qualification. | Choose only for prototyping or cost-driven non-automotive designs where AOI and AEC compliance are unnecessary. |
Compared with BZX8850S-C5V6-Q and MMSZ5232BS-7-F, the BZX8850S-B5V6-QYL provides superior voltage accuracy, lower dynamic impedance, AEC-Q101 validation, and manufacturable side-wettable flanks-making it the sole choice for production automotive and high-reliability portable medical systems requiring verified low-current regulation.

FAQ
What is the minimum reverse current required to achieve rated Zener voltage?
The BZX8850S-B5V6-QYL is specified at IZ = 50 µA, where VZ = 5.49 V to 5.71 V. Below 50 µA, voltage drops nonlinearly; operation below 10 µA yields <5.0 V and is not guaranteed. For stable regulation, maintain ≥50 µA using appropriate series resistance.
Can this Zener be used in forward-biased ESD protection?
No-it is not rated or characterized for forward-biased ESD clamping. Its 0.9 V VF max at 10 mA reflects diode conduction, not ESD robustness. Use dedicated TVS diodes (e.g., PESD5V0S1BA) for IEC 61000-4-2 protection; this device functions only as a reverse-bias voltage reference or clamp.
How does the "intentional leakage" affect long-term reliability?
The elevated 2.0 µA leakage at 4.0 V is a controlled design feature per AN90031-not a degradation mechanism. Accelerated life testing under AEC-Q101 confirms no reliability impact; it enhances noise immunity without compromising MTTF or parametric drift over 15-year automotive service life.
Is the DFN1006BD-2 package compatible with standard reflow profiles?
Yes-Nexperia provides JEDEC J-STD-020-compliant reflow guidance for SOD882BD. Peak temperature must not exceed 260 °C for ≤30 seconds; ramp rates and soak times align with IPC-7095. Side-wettable flanks enable full solder joint inspection without X-ray.
