Product details
Overview
BZX8850-C30YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 30 V nominal with ±5 % tolerance. It delivers stable reference voltage at 50 µA test current, features 300 Ω differential resistance at 2 mA, and operates within −55 °C to +150 °C ambient range. Used in portable battery-powered sensor biasing and low-power analog reference circuits.
For engineers reviewing the BZX8850-C30YL datasheet, BZX8850-C30YL pinout, BZX8850-C30YL application, or BZX8850-C30YL equivalent, this page provides verified electrical characteristics, thermal behavior, SOD882 footprint compatibility, and real-world use context for low-current regulation in space-constrained designs.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 30 V at IZ = 2 mA, exhibiting a temperature coefficient of +24.4 mV/K and reverse leakage ≤0.05 µA at VR = 29.4 V. Its 300 Ω dynamic impedance ensures stable regulation under light-load conditions typical in microcontroller reference rails.
The device uses silicon planar epitaxial construction and is optimized for low-bias operation, with intentional minor leakage rise per AN90031 to improve switching speed and reduce noise in signal conditioning paths. Thermal resistance from junction to ambient is 500 K/W on standard FR4 PCB.
Key Specifications

FAQ
What is the maximum reverse voltage before breakdown for BZX8850-C30YL?
The BZX8850-C30YL exhibits a sharp Zener breakdown onset between 28.5 V and 31.5 V at IZ = 2 mA. Below 28.5 V, reverse leakage remains ≤0.05 µA; sustained operation above 31.5 V risks exceeding absolute maximum ratings and may cause irreversible degradation.
Can BZX8850-C30YL be used in place of a 30 V Zener in an existing SOD-123 design?
No direct substitution is recommended without layout revision: BZX8850-C30YL uses SOD882 (1.0 × 0.6 mm), while SOD-123 measures 3.5 × 1.6 mm. Pad geometry, thermal relief, and solder paste volume differ significantly-rework requires footprint redesign and validation of thermal performance under load.
How does the ±5 % tolerance affect accuracy in a 30 V reference application?
At ±5 %, the actual Zener voltage ranges from 28.5 V to 31.5 V. For high-accuracy systems, this requires either system-level calibration or selection binning. In non-critical biasing (e.g., op-amp clamping), the full range remains functionally acceptable with no additional compensation.
Is BZX8850-C30YL suitable for automotive under-hood applications?
No-it is not AEC-Q200 qualified. While its −55 °C to +150 °C operating range meets some under-hood temperature requirements, Nexperia explicitly states non-automotive qualification for this series. Automotive use requires formal qualification evidence and is unsupported per manufacturer documentation.
