Product details
Overview
BZX8850S-B16-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 16 V Zener voltage at 50 µA test current, with ±2 % tolerance (B-series), 365 mW total power dissipation, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZX8850S-B16-QYL datasheet, BZX8850S-B16-QYL pinout, BZX8850S-B16-QYL application, or BZX8850S-B16-QYL equivalent, this device is selected for ultra-low-bias voltage stabilization in battery-powered sensors, ECU voltage monitoring rails, and portable instrumentation where side-wettable flanks enable reliable solder-joint inspection.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 15.20 V to 16.80 V at IZ = 50 µA, exhibiting a differential resistance ≤200 Ω at IZ = 5 mA and a temperature coefficient of +10.4 mV/K. Its low 50 µA test current enables stable regulation under microamp-level bias conditions typical in sleep-mode circuits.
The device uses a planar epitaxial silicon process and is packaged in a leadless DFN1006BD-2 (SOD882BD) footprint with side-wettable flanks-optimized for automated optical inspection (AOI) and high-yield reflow soldering on FR4 PCBs with single-sided copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.20 V to 16.80 V at IZ = 50 µA - defines precise regulation window for 16 V nominal rail stabilization |
| Tolerance | ±2 % (B-series) - ensures tight voltage accuracy without post-production trimming |
| Power Dissipation (Ptot) | 365 mW at Tamb ≤ 25 °C - supports continuous operation in thermally limited SMT layouts |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - enables low-loss forward conduction during transient polarity events |
| Junction Temperature (Tj) | −55 °C to +150 °C - guarantees functionality across automotive under-hood and industrial ambient extremes |
| Reverse Current (IR) | ≤ 0.05 µA at VR = 12.1 V - minimizes standby leakage in always-on monitoring circuits |
| Thermal Resistance (Rth(j-a)) | 340 K/W - quantifies self-heating impact on voltage drift in unheatsinked PCB mounting |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), ultra-small leadless surface-mount package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks for AOI-compatible solder joint verification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8840S-B16-Q | Same 16 V nominal, ±2 %, but rated at 250 mW Ptot and uses SOD882 (non-SWF) package | Lacks side-wettable flanks; unsuitable for AOI-dependent automotive production lines | Select when cost sensitivity outweighs solder-joint inspection requirements and thermal margin permits lower power rating |
| MMSZ5245B-TP | 16 V nominal, ±5 %, 500 mW Ptot, SOD-123 package; no AEC-Q101 qualification | Higher power but larger footprint (2.7 mm × 1.4 mm); not qualified for automotive use | Prefer for industrial non-automotive designs requiring higher surge tolerance and relaxed size constraints |
Compared with BZX8850S-B16-QYL, BZX8840S-B16-Q trades AOI capability and thermal headroom for lower unit cost, while MMSZ5245B-TP offers greater surge resilience in a legacy package but lacks automotive qualification and precision tolerance.

FAQ
What is the maximum reverse voltage this diode can withstand before breakdown?
The BZX8850S-B16-QYL has a nominal Zener voltage of 16 V, with a guaranteed breakdown range of 15.20 V to 16.80 V at 50 µA test current. Its absolute maximum reverse voltage is not defined independently-it operates within its specified VZ window under controlled bias; exceeding 16.80 V continuously risks thermal runaway if power dissipation limits are breached.
Does this part support reflow soldering with standard lead-free profiles?
Yes-BZX8850S-B16-QYL is qualified for lead-free reflow soldering per JEDEC J-STD-020. The DFN1006BD-2 package uses a standard footprint with side-wettable flanks, and Nexperia provides verified reflow profiles (peak 260 °C, 60-second duration above 217 °C) in Application Note AN10361.
How does the "B" suffix differ from "C" in the BZX8850S-Q series?
The "B" suffix denotes ±2 % Zener voltage tolerance (e.g., BZX8850S-B16-QYL), while "C" indicates approximately ±5 % tolerance (e.g., BZX8850S-C16-Q). Both share identical package, thermal specs, and AEC-Q101 qualification-but "B" parts are selected for tighter regulation accuracy in precision reference applications.
Can this diode be used in series or parallel configurations for higher voltage or current handling?
No-Zener diodes like BZX8850S-B16-QYL must not be paralleled due to mismatched VZ and thermal runaway risk. Series connection is possible for higher voltage, but requires individual current-limiting resistors and thermal derating per device; Nexperia does not characterize or recommend multi-device configurations for this series.
