Product details
Overview
BZX8850S-C6V8-QYL from Nexperia is a low-current Zener voltage regulator diode in the BZX8850S-Q series, 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 (C-series), 80 Ω differential resistance at 5 mA, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZX8850S-C6V8-QYL datasheet, BZX8850S-C6V8-QYL pinout, BZX8850S-C6V8-QYL application, or BZX8850S-C6V8-QYL equivalent, key selection criteria include ultra-low test current operation, side-wettable DFN1006BD-2 package for automated optical inspection, thermal resistance of 340 K/W, and intentional leakage optimization for noise-sensitive analog rails.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 6.46 V (min) to 7.14 V (max) at IZ = 50 µA, exhibiting a positive temperature coefficient of +1.2 mV/K. Its low 50 µA test current enables stable regulation in battery-powered sensor nodes where quiescent current must remain sub-100 µA.
The device features intentionally elevated reverse leakage (≤ 0.1 µA at VR = 5.1 V) per AN90031 to reduce switching transients and improve noise immunity in high-frequency analog front-ends. It is rated for 365 mW total power dissipation on FR4 PCB and supports non-repetitive surge up to 40 W for 100 µs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8840S-C6V8 | Same 6.8 V nominal, ±2 %, but rated for 300 mW Ptot and uses SOD323 package (1.7 mm × 1.3 mm) | Larger footprint; lacks side-wettable flanks and AEC-Q101 qualification | Select when cost sensitivity outweighs automotive compliance and AOI capability |
| MMSZ5235B-TP | 6.8 V, ±5 %, 500 mW Ptot, SOD-123 package; higher power but looser tolerance and no leakage optimization | Higher thermal mass; not qualified for automotive; unsuitable for noise-critical analog references | Choose only for non-automotive, high-current shunt regulation where size is secondary |
Compared with BZX8850S-C6V8-QYL, BZX8840S-C6V8 offers lower cost but sacrifices AEC-Q101 validation and AOI support, while MMSZ5235B-TP trades precision and noise performance for raw power handling-making the QYL variant optimal for compact, automotive-grade, low-noise reference designs.

FAQ
What is the maximum reverse voltage (VR) that BZX8850S-C6V8-QYL can withstand before breakdown?
The device exhibits a sharp, well-defined Zener breakdown at its nominal 6.8 V working voltage. At VR = 5.1 V, reverse current is guaranteed ≤ 0.1 µA; full regulation begins at 6.46 V (min) and extends to 7.14 V (max) under 50 µA test conditions. It is not rated for sustained operation above 7.14 V in regulation mode.
Can BZX8850S-C6V8-QYL be used in forward conduction mode?
Yes - it functions as a standard silicon diode in forward bias, with forward voltage ≤ 0.9 V at 10 mA. This allows dual-use in circuits requiring both reverse-bias regulation and forward-bias clamping or steering, though its primary design intent is Zener reference operation.
How does the "C" suffix in BZX8850S-C6V8-QYL affect its electrical behavior compared to "B"-series variants?
The "C" denotes ±2 % tolerance (vs. ±5 % for "B"), tighter differential resistance (80 Ω vs. 160 Ω for B6V2), and optimized leakage characteristics per AN90031. These differences directly improve voltage accuracy, load regulation, and noise performance in precision analog applications.
Is the DFN1006BD-2 package compatible with standard reflow profiles for lead-free soldering?
Yes - Nexperia provides validated reflow footprint data (Fig. 10) and recommends peak temperatures up to 260 °C for ≤ 30 seconds. The side-wettable flanks ensure reliable solder fillet formation and compatibility with IPC-A-610 Class 2 and Class 3 assembly standards.
