Product details
Overview
BZX8850S-C13-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 13 V regulation at 50 µA test current, with ±5 % tolerance, 170 Ω differential resistance at 5 mA, and 0.05 µA reverse leakage at rated voltage - optimized for portable battery-powered systems and automotive sensor interfaces.
For engineers reviewing the BZX8850S-C13-QYL datasheet, BZX8850S-C13-QYL pinout, BZX8850S-C13-QYL application, or BZX8850S-C13-QYL equivalent, this page provides verified package dimensions, thermal resistance (340 K/W), forward voltage (≤0.9 V @ 10 mA), AEC-Q101 qualification status, and side-wettable flank solderability for automated optical inspection (AOI) in high-reliability SMT assembly.
Technical Context
This device operates as a two-terminal shunt voltage regulator, conducting in reverse breakdown to maintain stable DC voltage across its terminals under varying load or supply conditions. Its specified 13 V nominal Zener voltage is guaranteed at IZ = 50 µA, with temperature coefficient of +7.0 mV/K and diode capacitance of 80 pF at 0 V - enabling predictable behavior in low-frequency reference and clamping functions.
The DFN1006BD-2 (SOD882BD) package features side-wettable flanks for reliable reflow solder joint inspection, and its ultra-small 1.0 mm × 0.6 mm footprint supports high-density PCB layouts. Thermal resistance from junction to ambient is 340 K/W on standard FR4, limiting continuous power dissipation to 365 mW at Tamb ≤ 25 °C.
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 |
|---|---|---|---|
| BZX84-C13 | SO-323 package (2.1 mm × 1.25 mm); 500 mW Ptot; ±5 % tolerance; rdiff = 30 Ω @ 5 mA | Larger footprint and higher power handling; less suitable for ultra-dense layouts | Select when higher surge immunity or manual rework accessibility is required |
| MMSZ5243B | SOD-123 package (3.7 mm × 1.6 mm); 500 mW Ptot; ±5 % tolerance; rdiff = 25 Ω @ 20 mA | Higher test current (20 mA), lower dynamic impedance, but no AEC-Q101 qualification | Choose for non-automotive consumer applications where tighter regulation is prioritized over qualification |
Compared with BZX8850S-C13-QYL, BZX84-C13 offers lower dynamic impedance but lacks side-wettable flanks and AEC-Q101 validation; MMSZ5243B provides superior regulation stability at higher currents but cannot be used in automotive production without additional qualification testing.

FAQ
What is the maximum continuous reverse power dissipation for BZX8850S-C13-QYL?
The maximum continuous total power dissipation is 365 mW at ambient temperature ≤25 °C when mounted on a standard FR4 PCB with single-sided copper. Derating is required above 25 °C at 3.65 mW/°C, based on a thermal resistance of 340 K/W junction-to-ambient.
Does BZX8850S-C13-QYL support automated optical inspection (AOI) during SMT assembly?
Yes - its DFN1006BD-2 (SOD882BD) package features side-wettable flanks, allowing AOI systems to verify solder joint formation on the lateral edges without requiring X-ray inspection, improving yield and reducing process cost in high-volume automotive manufacturing.
How does the 50 µA test current affect circuit design compared to standard 5 mA Zeners?
Specifying regulation at 50 µA enables use in ultra-low-power bias networks where current budgets are limited to sub-100 µA. Designers must account for higher dynamic impedance (170 Ω vs. ~30 Ω at 5 mA), which increases output voltage variation under load changes - best suited for high-impedance reference paths, not active current sinks.
Is BZX8850S-C13-QYL qualified for under-hood automotive environments?
Yes - it is fully qualified to AEC-Q101, with guaranteed operation from −55 °C to +150 °C junction temperature and validated reliability for automotive applications including engine control modules, body electronics, and ADAS sensor subsystems.
