Product details
Overview
BZX8850S-B10-QYL from Nexperia is a low-current Zener voltage regulator diode in an ultra-small DFN1006BD-2 (SOD882BD) package, designed for precision biasing and voltage reference in space-constrained, battery-powered systems. It delivers a nominal 10 V regulation at 50 µA test current, with ±2 % tolerance, 365 mW total power dissipation, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZX8850S-B10-QYL datasheet, BZX8850S-B10-QYL pinout, BZX8850S-B10-QYL application, or BZX8850S-B10-QYL equivalent, this device serves as a compact, low-leakage voltage reference for sensor signal conditioning, microcontroller reset circuits, and portable power rail monitoring where stable low-current regulation is critical.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 9.50 V to 10.50 V at IZ = 50 µA, exhibiting a differential resistance of ≤150 Ω at 5 mA and a temperature coefficient of +4.5 mV/K. Its low 50 µA test current enables minimal quiescent current draw in always-on circuits.
The device features side-wettable flanks for automated optical solder-joint inspection and is rated for junction temperatures up to 150 °C. Reverse leakage remains ≤0.1 µA at VR = 7.6 V, supporting high-impedance reference node integrity in low-power designs.

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-C10-Q | ±5 % tolerance (vs. ±2 %), identical package and 10 V nominal rating | Acceptable where cost sensitivity outweighs precision requirements | Select for non-critical biasing where 10 V ±0.5 V suffices and AEC-Q101 compliance is retained |
| MMSZ4686T1G | 10 V nominal, ±5 %, SOD-123 package (2.7 mm × 1.6 mm), 500 mW Ptot | Larger footprint; higher power but no side-wettable flanks or AEC-Q101 rating | Choose when board space permits larger package and automotive qualification is not required |
Compared with BZX8850S-B10-QYL, the C10-Q offers relaxed tolerance at identical size and qualification, while MMSZ4686T1G trades miniaturization and automotive compliance for higher power and legacy packaging - making the B10-QYL optimal for space- and reliability-critical automotive and portable designs.

FAQ
What is the maximum reverse voltage before breakdown for BZX8850S-B10-QYL?
The device is specified to regulate at 9.50 V to 10.50 V when reverse-biased at 50 µA. Breakdown begins near the lower limit of that range; applying >10.5 V continuously exceeds its rated working voltage and risks thermal runaway if current is not limited externally.
Can BZX8850S-B10-QYL be used in parallel for higher power handling?
No - Zener diodes exhibit manufacturing spread in breakdown voltage, causing current hogging in parallel configurations. This part is rated for 365 mW single-device operation; higher power requires series resistor derating or alternative topology such as active regulation.
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, and the side-wettable flanks enable full solder-joint verification using standard AOI systems without X-ray.
Does BZX8850S-B10-QYL require a heatsink in typical applications?
No - with Rth(j-a) = 340 K/W and a 365 mW power limit, self-heating remains below 125 °C junction rise even on minimal FR4 copper. Heatsinking is unnecessary unless ambient exceeds 85 °C or power approaches 200 mW continuously.
