Product details
Overview
BZX8850S-C2V4-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 portable electronics. It delivers a nominal 2.4 V regulation at 50 µA test current, with ±2 % tolerance, 200 mA maximum forward current, and 365 mW total power dissipation at 25 °C ambient.
For engineers reviewing the BZX8850S-C2V4-QYL datasheet, BZX8850S-C2V4-QYL pinout, BZX8850S-C2V4-QYL application, or BZX8850S-C2V4-QYL equivalent, this device is selected for low-leakage, low-power voltage stabilization in battery-powered sensor nodes, automotive body electronics, and wearables requiring AEC-Q101 qualified components and side-wettable flanks for automated optical inspection.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 2.28 V to 2.52 V at IZ = 50 µA, exhibiting a temperature coefficient of −3.5 mV/K and differential resistance ≤600 Ω at 5 mA. Its low 50 µA test current enables stable regulation under micro-power conditions where traditional Zeners fail to activate.
The device features intentional minor leakage optimization per AN90031 for fast switching and noise reduction in signal conditioning paths, and is qualified to AEC-Q101 for automotive under-hood and cabin applications up to 150 °C junction temperature.

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-B2V4-Q | Same 2.4 V nominal voltage but ±5 % tolerance (vs. ±2 % for C-series) | Acceptable where cost sensitivity outweighs precision; higher unit-to-unit variation affects multi-sensor calibration | Select when budget constraints dominate and system-level calibration compensates for wider VZ spread |
| MMSZ4676T1G | 2.4 V nominal, ±5 %, SOD-123 package (1.7 × 1.3 × 0.9 mm), 500 mW Ptot, no AEC-Q101 qualification | Larger footprint and unqualified for automotive; suitable only for commercial-grade consumer devices | Choose only for non-automotive, non-critical applications where board space and qualification are not limiting |
Compared with BZX8850S-C2V4-QYL, the B-series offers lower cost but reduced accuracy, while MMSZ4676T1G trades AEC-Q101 compliance and miniaturization for higher power handling and broader commercial availability-making the C-series optimal for precision automotive and portable medical designs.

FAQ
What is the maximum reverse voltage this Zener can regulate stably?
The BZX8850S-C2V4-QYL is rated for stable Zener operation up to its nominal 2.4 V working voltage, with guaranteed regulation between 2.28 V and 2.52 V at 50 µA. It must not be subjected to reverse voltages exceeding its absolute maximum rating of 2.52 V for extended periods without current limiting, as sustained overvoltage risks thermal runaway due to its 365 mW power limit.
Does this part support reflow soldering with standard lead-free profiles?
Yes - the DFN1006BD-2 package is qualified for lead-free reflow soldering per J-STD-020. The recommended peak temperature is 260 °C with ≤60 seconds above 217 °C. The side-wettable flanks ensure reliable solder joint formation and AOI compatibility on standard SMT lines using the footprint defined in Figure 10 of the datasheet.
How does the "C" suffix differ from "B" in the BZX8850S-Q series?
The "C" suffix denotes ±2 % voltage tolerance at 50 µA test current, while "B" indicates approximately ±5 %. Both share identical package, power rating, and AEC-Q101 qualification, but the C-series provides tighter regulation critical for precision analog references and multi-device matching in sensor arrays.
Can this Zener be used in forward-bias mode as a regular diode?
Yes - it exhibits a typical forward voltage of 0.9 V at 10 mA, making it usable as a low-drop rectifier or clamp in low-current signal paths. However, its primary design intent and characterization are for reverse-bias Zener regulation; forward characteristics are secondary and not optimized for high-speed or high-current switching applications.
