Product details
Overview
BZX8850S-C2V0-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 2.0 V Zener voltage at 50 µA test current, with ±5 % tolerance, 365 mW total power dissipation, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the BZX8850S-C2V0-QYL datasheet, BZX8850S-C2V0-QYL pinout, BZX8850S-C2V0-QYL application, or BZX8850S-C2V0-QYL equivalent, this device is selected for low-quiescent-current voltage stabilization in battery-powered sensors, microcontroller reset circuits, and automotive body-control modules where side-wettable flanks support automated optical inspection (AOI) during reflow soldering.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 2.0 V (C-series, ±5 %), measured at IZ = 50 µA - enabling stable regulation under ultra-low bias conditions. Its differential resistance is ≤600 Ω at IZ = 50 µA and ≤100 Ω at IZ = 1 mA, supporting predictable impedance behavior across operating currents.
The device features intentional minor leakage current optimization per AN90031 to improve switching speed and reduce noise in signal conditioning paths. Thermal resistance from junction to ambient is 340 K/W on standard FR4 PCB, and it supports ambient temperatures from −55 °C to +150 °C with a maximum junction temperature of 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.0 V nominal, ±5 % tolerance at IZ = 50 µA - ensures tight voltage reference for low-power analog sensing and MCU brown-out detection. |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - enables reliable forward conduction in dual-role protection/reference circuits. |
| Total Power Dissipation (Ptot) | 365 mW at Tamb ≤ 25 °C on standard FR4 PCB - defines safe continuous operation envelope in compact layouts. |
| Differential Resistance (rdiff) | ≤600 Ω at IZ = 50 µA; ≤100 Ω at IZ = 1 mA - determines output impedance stability across load variations. |
| Reverse Current (IR) | ≤1.0 µA at VR = 1.0 V - guarantees minimal standby leakage in always-on battery monitoring nodes. |
| Temperature Coefficient (SZ) | −3.5 mV/K - quantifies voltage drift over temperature, critical for accuracy in wide-range automotive environments. |
| Package | DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm - ultra-miniature leadless package with side-wettable flanks for AOI-compatible reflow assembly. |

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-B2V0-Q | Same 2.0 V nominal voltage but ±2 % tolerance (vs. ±5 %); higher test current (5 mA vs. 50 µA). | Better voltage accuracy but higher minimum bias requirement - unsuitable for sub-µA standby circuits. | Select when absolute voltage precision outweighs ultra-low current operation. |
| MMSZ4678T1G | 2.0 V Zener, SOD-123 package, ±5 %, rated at IZ = 5 mA; no AEC-Q101 qualification. | Larger footprint (2.7 mm × 1.4 mm), lacks automotive qualification and side-wettable flanks. | Choose only for non-automotive, cost-sensitive designs where board space is not constrained. |
Compared with BZX8850S-B2V0-Q, the C2V0 variant trades tighter tolerance for lower test current and automotive qualification; versus MMSZ4678T1G, it offers superior manufacturability via SWF and guaranteed AEC-Q101 compliance at identical voltage grade but in half the footprint.

FAQ
What is the maximum reverse voltage before breakdown for BZX8850S-C2V0-QYL?
The nominal Zener voltage is 2.0 V with ±5 % tolerance, meaning breakdown occurs between 1.88 V and 2.12 V at IZ = 50 µA. Absolute maximum reverse voltage is not defined - operation beyond VZ + margin risks exceeding Ptot = 365 mW or junction temperature limits. Designers must use series current limiting to maintain safe dissipation.
Does BZX8850S-C2V0-QYL support reflow soldering with standard lead-free profiles?
Yes - the DFN1006BD-2 package is qualified for standard JEDEC J-STD-020 lead-free reflow profiles. Nexperia provides dedicated footprint data (Fig. 10) with 0.65 mm pitch, 0.7 mm solder land width, and side-wettable flanks to ensure joint integrity and AOI compatibility under peak temperatures up to 260 °C.
How does the "C" suffix differ from "B" in the BZX8850S-Q series?
The "C" suffix denotes ±5 % tolerance and optimized leakage characteristics per AN90031 for fast switching and noise reduction; "B" indicates ±2 % tolerance and standard leakage. Both share identical package, power rating, and thermal specs, but C-series prioritizes low-current stability and EMI performance over absolute voltage accuracy.
Is BZX8850S-C2V0-QYL suitable for bidirectional ESD protection?
No - it is a unidirectional Zener diode intended for DC voltage regulation only. Its forward voltage is ≤0.9 V and reverse breakdown is sharp at ~2.0 V, but it lacks symmetric clamping, specified ESD ratings (e.g., IEC 61000-4-2), or bidirectional architecture. Use dedicated TVS diodes like PESD5V0S1BA for ESD protection.
