Product details
Overview
BZX8850S-C2V2-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 2.2 V regulation at 50 µA test current, with ±2 % tolerance (C-series), 600 Ω differential resistance at 5 mA, and 4 µA max reverse leakage at rated voltage - optimized for battery-powered sensors and automotive microcontroller reset circuits.
For engineers reviewing the BZX8850S-C2V2-QYL datasheet, BZX8850S-C2V2-QYL pinout, BZX8850S-C2V2-QYL application, or BZX8850S-C2V2-QYL equivalent, this device is selected for ultra-low-bias voltage reference, AEC-Q101-qualified automotive subsystems, and high-density PCB designs requiring side-wettable flanks for automated optical inspection (AOI) and solder joint reliability.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 2.09 V to 2.31 V at 50 µA, exhibiting a negative temperature coefficient of −3.5 mV/K and 210 pF junction capacitance at 0 V. Its low 50 µA test current enables stable regulation in micropower circuits where quiescent current must remain below 100 µA.
The device uses a planar silicon process with intentional minor leakage optimization per AN90031, enabling faster transient response and reduced noise in voltage-sensing paths. It is qualified to AEC-Q101 with 150 °C maximum junction temperature and rated for operation from −55 °C to +150 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 2.2 V at IZ = 50 µA - defines precise low-voltage reference point for MCU brown-out detection |
| Voltage Tolerance | ±2 % (C-series) - ensures tight regulation across production lots without post-assembly trimming |
| Differential Resistance (rdiff) | 600 Ω max at IZ = 5 mA - limits output impedance for stable reference under small load variations |
| Reverse Leakage Current (IR) | ≤ 4 µA at VR = 2.2 V - minimizes standby power loss in always-on sensor nodes |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - supports bidirectional protection or dual-use as clamp diode in level-shifting interfaces |
| Total Power Dissipation (Ptot) | 365 mW at Tamb ≤ 25 °C on FR4 PCB - sets thermal derating boundary for compact 2-layer board layouts |
| Junction-to-Ambient Thermal Resistance | 340 K/W - informs thermal design margin when operating near 150 °C max junction temperature |

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-B2V2-Q | ±5 % tolerance (B-series), same 2.2 V nominal, higher rdiff (600 Ω typ vs. 600 Ω max), identical package and AEC-Q101 rating | Suitable for non-critical biasing where cost sensitivity outweighs regulation accuracy | Select when ±5 % tolerance is acceptable and tighter tempco or leakage specs are not required. |
| MMSZ4678T1G | 2.2 V nominal, ±5 %, SOD-123 package (larger), 500 mW Ptot, no AEC-Q101 qualification, 100 nA leakage at 1 V | Targeted at commercial-grade consumer power supplies, not automotive or industrial environments | Choose only for non-automotive applications where board space is less constrained and qualification is not mandated. |
Compared with BZX8850S-C2V2-QYL, the B-series variant trades regulation accuracy for cost in non-precision roles, while MMSZ4678T1G lacks automotive qualification and side-wettable flanks - making the C-series QYL version uniquely suited for high-reliability, space-limited automotive and industrial edge nodes.

FAQ
What is the maximum reverse voltage this diode can withstand before breakdown?
The BZX8850S-C2V2-QYL is specified for nominal 2.2 V Zener voltage at 50 µA test current, with guaranteed breakdown occurring between 2.09 V and 2.31 V. Its absolute maximum non-repetitive peak reverse voltage is not defined independently - it is governed by the 40 W surge rating at 100 µs pulse width, translating to ~28 V peak for that duration. Continuous reverse operation above 2.31 V will exceed regulation tolerance and increase power dissipation beyond safe limits.
Does this part support reflow soldering with standard lead-free profiles?
Yes - the DFN1006BD-2 (SOD882BD) package is qualified for lead-free reflow per JEDEC J-STD-020. The recommended peak temperature is 260 °C for ≤ 30 seconds, with ramp rates and soak profiles matching IPC/JEDEC J-STD-020D. The side-wettable flanks are explicitly designed to support automated optical inspection of solder fillets after standard reflow.
How does the "intentional minor rise of leakage current" affect circuit performance?
Per AN90031, the controlled leakage increase reduces minority-carrier lifetime, yielding faster turn-off response and lower broadband noise in dynamic regulation scenarios. In practice, this means improved transient rejection in feedback loops and reduced 1/f noise in precision reference applications - without compromising DC accuracy or long-term stability.
Is the cathode marking visible under standard AOI systems?
Yes - the cathode is marked by a laser-etched bar on the top surface of the DFN1006BD-2 package, positioned adjacent to pin 1. This marking meets IPC-A-610 Class 2/3 visibility requirements and is fully compatible with industry-standard AOI systems configured for 10 µm resolution and side-wettable flank inspection protocols.
