Product details
Overview
BZX8850S-C30-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 30 V Zener voltage at 50 µA test current, with ±5 % tolerance, 300 Ω differential resistance at 5 mA, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZX8850S-C30-QYL datasheet, BZX8850S-C30-QYL pinout, BZX8850S-C30-QYL application, or BZX8850S-C30-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-flank solderability and thermal reliability are critical.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 28.5 V (min) to 31.5 V (max) at IZ = 50 µA, exhibiting a temperature coefficient of +0.05 mV/K and reverse current ≤0.05 µA at VR = 29.4 V. Its low 50 µA test current enables stable regulation under micro-power bias conditions.
The device uses a planar epitaxial silicon process and is packaged in a leadless DFN1006BD-2 (SOD882BD) footprint with side-wettable flanks for automated optical solder-joint inspection. Junction-to-ambient thermal resistance is 340 K/W on standard FR4 PCB, supporting operation from −55 °C to +150 °C ambient.

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-C30 | SO-34 package (SOT-23), 500 mW Ptot, ±5 %, 30 V @ 5 mA test current | Larger footprint, higher power, no AEC-Q101 qualification | Select when board space allows larger package and automotive qualification is not required |
| MMSZ5256ET1G | SOD-123 package, 500 mW Ptot, ±5 %, 30 V @ 20 mA test current, 35 Ω rdiff | Higher test current, lower dynamic impedance, no side-wettable flanks | Select when lower impedance and higher bias current are acceptable, and AOI support is not needed |
Compared with BZX8850S-C30-QYL, BZX84-C30 offers higher power but lacks automotive qualification and compactness, while MMSZ5256ET1G provides lower impedance at higher bias but sacrifices low-current stability and manufacturability features like side-wettable flanks.

FAQ
What is the Zener voltage tolerance and test condition for BZX8850S-C30-QYL?
The BZX8850S-C30-QYL has a ±5 % tolerance on its nominal 30 V Zener voltage, specified at a test current of 50 µA. This low test current enables accurate regulation in micro-power applications such as battery-backed sensors and always-on monitoring circuits where bias current must be minimized.
Is BZX8850S-C30-QYL suitable for automotive applications?
Yes - it is qualified to AEC-Q101 for stress testing including temperature cycling, high-temperature reverse bias, and humidity testing. Its operating ambient range of −55 °C to +150 °C and junction temperature limit of 150 °C make it appropriate for under-hood and cabin ECU applications.
How does the side-wettable flank design benefit manufacturing?
The DFN1006BD-2 package features side-wettable flanks that allow automated optical inspection (AOI) of solder joint integrity without requiring X-ray equipment. This improves first-pass yield and reduces post-reflow rework in high-volume SMT lines, especially for compact consumer and automotive modules.
What is the maximum reverse current at rated Zener voltage?
At VR = 29.4 V (98 % of min VZ), the reverse current is guaranteed ≤0.05 µA. This ultra-low leakage supports stable reference performance in high-impedance bias networks and extends battery life in portable instrumentation where standby current is critical.
