Product details
Overview
BZX8850S-C22-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 22 V Zener voltage (VZ = 20.9–23.1 V at IZ = 50 µA), ±2 % tolerance (C-series), 365 mW total power dissipation, and features side-wettable flanks for automated optical solder-joint inspection. It is AEC-Q101 qualified and used in automotive body control modules for sensor biasing and microcontroller supply rail stabilization.
For engineers reviewing the BZX8850S-C22-QYL datasheet, BZX8850S-C22-QYL pinout, BZX8850S-C22-QYL application, or BZX8850S-C22-QYL equivalent, key selection criteria include its ultra-low test current (50 µA), tight 2 % VZ tolerance, DFN1006BD-2 package with cathode marking, and intentional leakage optimization for noise-sensitive analog front-ends.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified VZ of 20.9–23.1 V at IZ = 50 µA and exhibits a temperature coefficient of +16.4 mV/K. Its differential resistance is ≤250 Ω at IZ = 5 mA, supporting stable regulation under light-load conditions typical in battery-backed real-time clocks and EEPROM backup circuits.
The device uses a silicon planar Zener structure optimized for low leakage and fast transient response. Its 0.65 mm pitch, 1.0 × 0.6 mm DFN1006BD-2 package enables high-density PCB layouts while maintaining thermal resistance of 340 K/W (junction-to-ambient, FR4 single-sided copper).
Key Specifications

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-B22-Q | ±5 % VZ tolerance (21.6–22.4 V), higher leakage at 100 µA vs. C-series | Suitable for non-critical biasing where cost sensitivity outweighs precision | Select when ±5 % regulation is acceptable and unit cost reduction is prioritized over long-term stability |
| MMSZ5247B-7-F | 20 V nominal, ±5 %, SOD-123 package (2.7 × 1.6 mm), 500 mW Ptot | Larger footprint and higher power rating; less suitable for ultra-dense automotive PCBs | Choose only if board layout permits larger package and higher power margin is required for surge handling |
Compared with BZX8850S-C22-QYL, the BZX8850S-B22-Q trades precision for cost in non-automotive applications, while MMSZ5247B-7-F sacrifices miniaturization for higher surge capability-neither offers the combined AEC-Q101 qualification, 2 % tolerance, and DFN1006BD-2 footprint of the original.

FAQ
What is the maximum reverse voltage (VR) this diode can withstand before breakdown?
The BZX8850S-C22-QYL has no defined "maximum reverse voltage" prior to breakdown-it is a Zener diode designed to operate in controlled reverse breakdown. Its nominal Zener voltage is 22 V (20.9–23.1 V), and it begins regulating at approximately 90 % of VZ. Absolute maximum reverse voltage is not specified because operation is intended within the Zener region, not as a blocking diode.
Can this diode be used in parallel for higher current handling?
No-Zener diodes exhibit negative temperature coefficients and parameter spread, causing current hogging when paralleled. Even matched units will not share current evenly due to VZ tolerance (±2 %) and thermal coupling differences. For higher current, select a single higher-power Zener or use an active regulator instead.
Is the cathode marking visible under standard optical inspection?
Yes-the cathode is indicated by a laser-marked bar on the top surface of the DFN1006BD-2 package. The side-wettable flanks and standardized 0.65 mm pitch allow reliable detection using standard AOI systems calibrated for 0201-class components.
Does this part support reflow soldering per JEDEC J-STD-020?
Yes-Nexperia specifies the DFN1006BD-2 package for lead-free reflow per JEDEC J-STD-020D. Peak temperature is rated to 260 °C for 30 seconds, compatible with standard Pb-free profiles. Footprint dimensions (1.0 mm × 0.6 mm lands, 0.4 mm solder mask opening) are provided in Figure 10 of the datasheet.
