Product details
Overview
BZX8850-B3V0YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 3.0 V nominal with ±2 % tolerance. It delivers stable reference voltage at 50 µA test current, exhibits 0.8 µA max reverse leakage at VR = 1.0 V, and supports total power dissipation up to 250 mW in FR4 PCB mounting. It is used in battery-powered sensor biasing and low-power microcontroller reset circuits.
For engineers reviewing the BZX8850-B3V0YL datasheet, BZX8850-B3V0YL pinout, BZX8850-B3V0YL application, or BZX8850-B3V0YL equivalent, this page provides verified electrical characteristics, thermal resistance (500 K/W), differential resistance (600 Ω at IZ = 50 µA), cathode/anode terminal mapping, and direct alternatives for low-bias voltage reference design.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal working voltage of 3.0 V and tight ±2 % tolerance (B-series). Its specified test current of 50 µA enables ultra-low quiescent current operation, making it suitable for energy-constrained systems where standby current must remain below 1 µA.
The device features a differential resistance of 600 Ω at IZ = 50 µA and 100 Ω at IZ = 1 mA, indicating predictable impedance behavior across its regulation range. Its temperature coefficient is −3.5 mV/K, ensuring stable voltage output over ambient temperatures from −55 °C to +150 °C.

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-C3V0 | ±5 % tolerance, SOT-23 package (3.0 × 1.4 mm), 350 mW Ptot, 5 mA test current | Higher power and looser tolerance; suited for non-critical supply rail clamping | Select when board space allows larger package and ±5 % regulation is acceptable |
| MMSZ5226B | ±5 % tolerance, SOD-123 package (2.7 × 1.4 mm), 500 mW Ptot, 20 mA test current | Higher test current and power rating; requires stronger bias source | Choose for higher-current regulation where 3.0 V reference stability under load >1 mA matters |
Compared with BZX8850-B3V0YL, BZX84-C3V0 offers greater power handling but sacrifices precision and size efficiency, while MMSZ5226B trades ultra-low bias capability for higher current robustness-making the BZX8850-B3V0YL optimal for space- and power-constrained 3.0 V reference designs.

FAQ
What is the maximum reverse leakage current for BZX8850-B3V0YL at 1.0 V?
The maximum reverse leakage current (IR) is 0.8 µA at VR = 1.0 V and Tj = 25 °C, as specified in Table 8 of the datasheet. This value remains stable across −55 °C to +125 °C ambient, supporting ultra-low-power standby modes in portable electronics without compromising regulation integrity.
Can BZX8850-B3V0YL be used in forward conduction mode?
Yes-it exhibits a forward voltage (VF) of 0.9 V at IF = 10 mA, enabling dual-use as both a Zener reference and a low-VF clamp diode. Its 200 mA absolute maximum forward current (IF) and 0.9 V VF make it suitable for low-loss signal routing or transient suppression in bidirectional I/O protection schemes.
How does the SOD882 package affect thermal performance?
Mounted on standard FR4 PCB with single-sided copper, the SOD882 package delivers a junction-to-ambient thermal resistance (Rth(j-a)) of 500 K/W. This limits continuous power dissipation to 250 mW at Tamb ≤ 25 °C; derating is required above 25 °C at 2.5 mW/°C to maintain Tj ≤ 150 °C.
Is BZX8850-B3V0YL suitable for automotive applications?
No-this part is not AEC-Q200 qualified and lacks automotive-specific testing or qualification. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products like BZX8850-B3V0YL are unsuitable for safety-critical or life-support systems, including automotive ECUs, ADAS sensors, or infotainment power rails.
