Product details
Overview
BZX8850S-B6V8-QYL from Nexperia is a low-current Zener voltage regulator diode in an ultra-small DFN1006BD-2 (SOD882BD) package, designed for precision biasing and voltage reference in space-constrained, low-power circuits. It delivers a nominal 6.8 V regulation at 50 μA test current, with ±2 % tolerance, 80 Ω differential resistance at 5 mA, and AEC-Q101 qualification for automotive signal conditioning and sensor supply rails.
For engineers reviewing the BZX8850S-B6V8-QYL datasheet, BZX8850S-B6V8-QYL pinout, BZX8850S-B6V8-QYL application, or BZX8850S-B6V8-QYL equivalent, this part supports low-leakage, stable reference generation in battery-powered instrumentation, automotive microcontroller reset circuits, and portable analog front-ends where minimal quiescent current and side-wettable flanks for solder inspection are critical.
Technical Context
This Zener diode operates in reverse breakdown with a specified working voltage of 6.66 V to 6.94 V at IZ = 50 μA, exhibiting a positive temperature coefficient of +1.2 mV/K and low 100 pF capacitance at 0 V. Its design targets low-bias operation, avoiding thermal runaway in high-impedance nodes.
The device uses a planar silicon process optimized for tight voltage distribution and controlled leakage; the B-series variant features intentional minor leakage rise to reduce switching noise-confirmed in Application Note AN90031-making it suitable for noise-sensitive analog references rather than pure shunt regulation.

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-C6V8-Q | ±5 % tolerance vs. ±2 %; higher max leakage (0.1 µA vs. 0.05 µA at VR = 5.1 V) | Suitable for non-critical biasing where cost sensitivity outweighs precision | Select when tighter voltage matching is unnecessary and BOM cost reduction is prioritized |
| MMSZ4688T1G | Same 6.8 V nominal, but SOD-123 package (2.7 × 1.6 mm); 500 mW Ptot; no AEC-Q101 rating | Used in consumer-grade power supplies where automotive qualification is not required | Choose only for non-automotive designs needing higher power margin and larger handling footprint |
Compared with BZX8850S-C6V8-Q, the BZX8850S-B6V8-QYL offers tighter regulation and lower leakage for precision analog use; versus MMSZ4688T1G, it trades package size and power headroom for automotive compliance and miniaturization-critical in ADAS camera modules and compact ECUs.

FAQ
What is the maximum reverse voltage this diode can withstand before breakdown?
The BZX8850S-B6V8-QYL has a nominal Zener voltage of 6.8 V, with guaranteed breakdown occurring between 6.66 V and 6.94 V at IZ = 50 μA. Its absolute maximum non-repetitive peak reverse voltage is not specified independently, but the device is rated for up to 40 W surge power at 100 μs pulse width-indicating robust transient handling within its defined Zener operating region.
Does this Zener diode support bidirectional clamping?
No-it functions unidirectionally as a reverse-biased Zener regulator. However, its forward voltage is specified at ≤0.9 V at 10 mA, enabling limited forward conduction for basic overvoltage clamping in low-energy scenarios. For true bidirectional protection, a dedicated TVS or dual-Zener array is required.
Can this part be used in reflow soldering processes?
Yes. The DFN1006BD-2 package is qualified for standard lead-free reflow profiles. Nexperia provides a dedicated solder footprint (Fig. 10) with 0.6 mm pad width, 0.7 mm pad length, and 0.65 mm pitch, and explicitly supports side-wettable flank inspection-ensuring reliable joint formation in automated SMT lines.
How does the "B" suffix differ from "C" in the BZX8850S-Q series?
The "B" suffix denotes ±2 % voltage tolerance and lower leakage current (e.g., 0.05 µA max at VR = 5.1 V), while "C" indicates approximately ±5 % tolerance and higher leakage (0.1 µA max). Both share identical package, thermal specs, and AEC-Q101 qualification-but "B" is selected for precision reference applications demanding tighter regulation and lower bias error.
