Product details
Overview
BZX8850S-C6V2-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 6.2 V Zener voltage at 50 µA test current, with ±2 % tolerance (C-series), 160 Ω dynamic resistance at 5 mA, and 0.4 mV/K temperature coefficient - optimized for battery-powered sensor nodes and automotive body electronics.
For engineers reviewing the BZX8850S-C6V2-QYL datasheet, BZX8850S-C6V2-QYL pinout, BZX8850S-C6V2-QYL application, or BZX8850S-C6V2-QYL equivalent, key selection criteria include its ultra-low 50 µA regulation current, side-wettable DFN1006BD-2 package for automated optical inspection, AEC-Q101 qualification, and intentional leakage tuning for noise-sensitive analog front-ends.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 5.89 V to 6.51 V at IZ = 50 µA, exhibiting tight differential resistance (160 Ω max at 5 mA) and low thermal drift (±0.4 mV/K). Its design targets stable biasing under minimal current draw, avoiding thermal runaway in thermally isolated PCB layouts.
The device uses a silicon planar epitaxial process and features side-wettable flanks for solder-joint reliability verification. Unlike standard Zeners, the C-series variant includes controlled leakage current elevation to suppress switching transients and reduce high-frequency noise coupling in signal conditioning paths.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8850S-B6V2-Q | ±5 % tolerance (vs. ±2 %); higher rdiff (≤200 Ω); no intentional leakage tuning | Suitable for non-critical biasing where cost sensitivity outweighs precision and noise performance | Select when budget constraints dominate and ±5 % VZ margin is acceptable in system design |
| MMSZ4687-TP | Same 6.2 V nominal, but SOD-123 package (2.7 mm × 1.6 mm); 500 mW Ptot; no AEC-Q101 qualification | Used in industrial power supplies where board space is less constrained and automotive compliance is not required | Choose for legacy designs using larger footprints or where higher power dissipation justifies larger package |
Compared with BZX8850S-B6V2-Q, the C6V2-Q offers tighter tolerance and lower noise; versus MMSZ4687-TP, it trades power headroom for AEC-Q101 compliance and 60 % smaller footprint - critical for next-gen automotive and portable medical PCBs.

FAQ
What is the maximum reverse current (IR) at 5.0 V for BZX8850S-C6V2-QYL?
At VR = 5.0 V and Tj = 25 °C, the maximum reverse current is 1.0 µA. This value reflects the diode's tight leakage control in the pre-breakdown region, supporting low-power standby modes in always-on sensor interfaces without compromising battery life.
Can BZX8850S-C6V2-QYL be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficients and mismatched breakdown characteristics that cause current hogging when paralleled. The device is rated for 365 mW total dissipation on FR4; higher power must be achieved via external series resistance or alternative topology.
Is the cathode marking visible under standard AOI systems?
Yes - the cathode is marked with a visible bar on the top surface of the DFN1006BD-2 package, and the side-wettable flanks enable reliable solder-joint inspection using standard 2D/3D AOI equipment calibrated for 0.6 mm pitch components.
Does the +0.4 mV/K temperature coefficient apply across the full operating range?
The +0.4 mV/K value is typical at 25 °C and applies within the 0 °C to 70 °C range; outside this, the coefficient increases nonlinearly up to +2.5 mV/K at 125 °C. System-level calibration should account for this curvature in high-accuracy applications.
