Product details
Overview
BZX8850-B30YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 30 V nominal with ±2 % tolerance. It delivers stable reference voltage at 50 µA test current, features 300 Ω differential resistance at 5 mA, and operates within −55 °C to +150 °C ambient range-ideal for battery-powered sensor biasing and low-power analog front-ends.
For engineers reviewing the BZX8850-B30YL datasheet, BZX8850-B30YL pinout, BZX8850-B30YL application, or BZX8850-B30YL equivalent, this page provides verified Zener voltage, thermal resistance, leakage behavior, and SOD882 footprint compatibility for compact PCB designs requiring stable low-current regulation.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 30 V at IZ = 50 µA, exhibiting a temperature coefficient of +24.4 mV/K and reverse current ≤0.05 µA at VR = 29.4 V. Its low 500 K/W junction-to-ambient thermal resistance enables reliable operation on FR4 PCBs without heatsinking.
The device uses silicon planar technology with intentional minor leakage optimization per AN90031, supporting fast switching transients and reduced noise in signal conditioning paths. Its 250 mW total power dissipation rating is specified under standard single-sided copper PCB mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 29.4 V to 30.6 V at IZ = 50 µA - defines tight regulation window for reference stability |
| Differential Resistance rdiff | 300 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Current IR | ≤ 0.05 µA at VR = 29.4 V - ensures minimal quiescent power loss in standby |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - supports low-loss forward conduction during transient clamping |
| Total Power Dissipation Ptot | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 |
| Junction Temperature Tj | 150 °C maximum - defines upper thermal limit for reliability under sustained bias |
| Package Thermal Resistance Rth(j-a) | 500 K/W - quantifies self-heating rise per watt on unmodified PCB layout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C30 | ±5 % tolerance, SOT-23 package (3.0 × 1.4 mm), 350 mW Ptot, rdiff = 35 Ω at 5 mA | Higher power and lower impedance but 5× larger footprint; suited for higher-current regulation | Select when board space permits and lower dynamic impedance is critical over tight voltage tolerance |
| MMSZ5257ET1G | ±5 % tolerance, SOD-123 package (3.7 × 1.6 mm), 500 mW Ptot, VZ = 30 V at 19.4 mA | Higher test current and power rating; less suitable for sub-100 µA bias applications | Choose for legacy SOD-123 layouts or where higher surge robustness outweighs size and low-current performance |
Compared with BZX8850-B30YL, BZX84-C30 offers lower dynamic impedance but looser voltage tolerance and larger footprint, while MMSZ5257ET1G provides higher surge capacity at the cost of increased bias current and board area-making BZX8850-B30YL optimal for space-constrained, ultra-low-quiescent designs.

FAQ
What is the Zener voltage tolerance for BZX8850-B30YL?
The 'B' suffix denotes ±2 % tolerance, meaning the measured Zener voltage falls between 29.4 V and 30.6 V when tested at 50 µA. This tighter tolerance reduces calibration effort in precision analog circuits compared to ±5 % 'C' series variants.
Can BZX8850-B30YL be used in place of a 30 V Zener with higher test current?
No-it is specified at 50 µA, not the conventional 5 mA or 20 mA. Substituting it into circuits designed for higher-test-current Zeners risks unstable regulation due to higher dynamic impedance (300 Ω vs. ~35 Ω) and nonlinear knee behavior below 100 µA.
Does the SOD882 package require special soldering profiles?
Yes-the DFN1006-2 footprint requires reflow profiles aligned with IPC-J-STD-020, using the recommended solder land pattern (0.6 mm pad length, 0.3 mm width, 0.7 mm spacing). Thermal relief and stencil aperture design must accommodate its 0.5 mm height and bottom-termination geometry.
How does the 'intentional minor rise of leakage current' affect circuit performance?
Per AN90031, this controlled leakage improves switching speed and reduces noise by optimizing carrier lifetime in the depletion region. In practice, it enables faster response to transient overvoltage events while maintaining <0.05 µA leakage at rated VR-beneficial for ESD-critical signal lines.
