Product details
Overview
BZX8850S-B15-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 15 V Zener voltage at 50 µA test current, with ±2 % tolerance (B-series), 200 mA maximum forward current, 365 mW total power dissipation, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZX8850S-B15-QYL datasheet, BZX8850S-B15-QYL pinout, BZX8850S-B15-QYL application, or BZX8850S-B15-QYL equivalent, this device is selected for ultra-low-bias voltage stabilization in battery-powered sensors, ECU reference rails, and portable instrumentation where side-wettable flanks support automated optical inspection (AOI) and reliable reflow soldering.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 14.7 V to 15.3 V at IZ = 50 µA, exhibiting a temperature coefficient of +9.2 mV/K and differential resistance of 200 Ω at IZ = 5 mA. Its low 50 µA test current enables stable regulation under micro-power bias conditions typical in always-on monitoring circuits.
The device uses a planar silicon junction structure housed in a DFN1006BD-2 (SOD882BD) package with side-wettable flanks, enabling high-density PCB layouts and compatibility with standard reflow profiles. Junction-to-ambient thermal resistance is 340 K/W on FR4 with single-sided copper, supporting operation up to 150 °C junction temperature.
Key Specifications

| MMSZ5245B-7-F | Same 15 V nominal, ±5 % tolerance, SOD-123 package (larger footprint, no side-wettable flanks), 500 mW Ptot | Preferred for legacy designs using through-hole or larger SMD footprints; lacks AEC-Q101 certification | Choose only if board layout prohibits DFN1006BD-2 or automotive qualification is not required |
Compared with BZX8850S-C15-Q, the BZX8850S-B15-QYL offers tighter voltage control critical for metrology; versus MMSZ5245B-7-F, it provides automotive qualification and AOI-compatible packaging at the expense of higher unit cost and smaller thermal margin.

FAQ
What is the Zener voltage tolerance for BZX8850S-B15-QYL?
The BZX8850S-B15-QYL has a ±2 % tolerance, meaning its Zener voltage is guaranteed between 14.7 V and 15.3 V when measured at 50 µA test current and 25 °C junction temperature. This tight tolerance eliminates the need for external calibration in precision analog circuits and supports first-pass design success in automotive reference rails.
Does BZX8850S-B15-QYL support automated optical inspection (AOI)?
Yes-its DFN1006BD-2 package features side-wettable flanks, allowing solder joint inspection from the side using standard AOI systems. This capability ensures process control in high-volume automotive PCB assembly and reduces field failure risk associated with insufficient solder fillet formation on bottom-terminated devices.
Can BZX8850S-B15-QYL be used in place of a standard 1N4744A?
No-it is not a direct replacement. While both regulate at ~15 V, the BZX8850S-B15-QYL is rated for 50 µA test current and 365 mW dissipation in a 1.0 mm × 0.6 mm DFN package, whereas the 1N4744A uses DO-41 packaging, 20 mA test current, and 1 W power rating. Substitution requires full thermal, bias, and layout validation.
Is BZX8850S-B15-QYL qualified for under-hood automotive applications?
Yes-this part is fully qualified to AEC-Q101, including stress tests for high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock. Its −55 °C to +150 °C operating junction temperature range and robust DFN package make it suitable for engine control units, transmission control modules, and other under-hood electronics.
