Product details
Overview
BZX8850S-C15-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 provides a nominal 15 V Zener voltage at 50 µA test current, with ±5 % tolerance, 200 mA maximum forward current, 365 mW total power dissipation, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZX8850S-C15-QYL datasheet, BZX8850S-C15-QYL pinout, BZX8850S-C15-QYL application, or BZX8850S-C15-QYL equivalent, this device is selected for ultra-low-bias voltage reference, ESD-protected signal-level clamping, and battery-powered sensor biasing where side-wettable flanks support automated optical inspection (AOI) and reliable reflow soldering on FR4 PCBs.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified VZ = 14.25 V to 15.75 V at IZ = 50 µA, exhibiting low differential resistance (200 Ω max) and a temperature coefficient of +9.2 mV/K. Its design targets stable regulation under minimal bias current, making it suitable for standby circuits and micro-power analog front-ends.
The device uses a DFN1006BD-2 (SOD882BD) leadless package with side-wettable flanks, enabling high-density placement and compatibility with standard reflow profiles. Its junction-to-ambient thermal resistance is 340 K/W on single-sided FR4, supporting operation from −55 °C to +150 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.25 V to 15.75 V at IZ = 50 µA - defines precise regulation point for low-current reference applications |
| Tolerance | ±5 % - supports cost-optimized designs where tighter tolerance is not required |
| Differential Resistance (rdiff) | ≤200 Ω at IZ = 5 mA - ensures stable output voltage under small load variations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C15 | SO-34 (SOT-23) package; 350 mW Ptot; ±5 % tolerance; VZ = 14.3–15.7 V at IZ = 5 mA | Larger footprint; higher rdiff (300 Ω); no AEC-Q101 qualification | Select when board space allows larger package and automotive qualification is unnecessary |
| MMSZ5245B | SOD-123 package; 500 mW Ptot; ±5 % tolerance; VZ = 14.25–15.75 V at IZ = 20 mA | Higher test current; 10× higher leakage (0.5 µA); no side-wettable flanks | Select when higher power handling is needed and AOI capability is not required |
Compared with BZX8850S-C15-QYL, BZX84-C15 offers legacy compatibility but lacks SWF and automotive qualification, while MMSZ5245B trades miniaturization for higher leakage and less precise low-current regulation-making the BZX8850S-C15-QYL optimal for next-gen compact, automotive-grade, low-leakage designs.

FAQ
What is the Zener voltage tolerance and test condition for BZX8850S-C15-QYL?
The BZX8850S-C15-QYL has a ±5 % Zener voltage tolerance, specified at a test current of 50 µA. Its nominal VZ is 15 V, with a guaranteed range of 14.25 V to 15.75 V under those conditions. This low-current specification makes it ideal for battery-powered and ultra-low-power applications where traditional 5 mA Zener testing would be impractical.
Does BZX8850S-C15-QYL support automated optical inspection (AOI)?
Yes - the DFN1006BD-2 (SOD882BD) package features side-wettable flanks, allowing solder joint inspection via AOI systems after reflow. This design meets IPC-A-610 Class 2/3 requirements and is validated for use with standard stencil thicknesses and reflow profiles on FR4 PCBs.
How does the leakage current behavior differ between BZX8850S-Bxx-Q and BZX8850S-Cxx-Q variants?
The BZX8850S-C15-QYL exhibits an intentionally elevated reverse leakage current compared to its B-series counterpart, optimized per AN90031 for faster switching response and reduced noise in dynamic biasing applications. At VR = 11.4 V, leakage is ≤0.05 µA - a controlled trade-off that improves transient stability without compromising regulation accuracy.
Can BZX8850S-C15-QYL be used in place of a standard 15 V Zener in existing SOT-23 designs?
No - the BZX8850S-C15-QYL uses a DFN1006BD-2 (1.0 mm × 0.6 mm) package incompatible with SOT-23 footprints. It requires dedicated layout with 0.65 mm pitch and side-wettable flank solder pads. Electrical substitution is possible only after verifying thermal limits, leakage, and low-current regulation behavior in the target circuit.
