Product details
Overview
BZX8850-B5V6YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 5.6 V nominal with ±2 % tolerance. It delivers stable reference voltage at 50 µA test current, features 400 Ω differential resistance at 5 mA, and operates within −55 °C to +150 °C ambient range. Used in portable battery-powered sensor biasing and low-power microcontroller reset circuits.
For engineers reviewing the BZX8850-B5V6YL datasheet, BZX8850-B5V6YL pinout, BZX8850-B5V6YL application, or BZX8850-B5V6YL equivalent, this page provides verified electrical parameters, thermal behavior, SOD882 footprint compatibility, and real-world use cases for low-bias voltage reference design.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified nominal Zener voltage of 5.6 V at IZ = 50 µA, exhibiting a temperature coefficient of −2.0 mV/K and typical capacitance of 120 pF at 0 V. Its low leakage current and intentional minor rise in IR support fast switching and noise reduction per AN90031.
The device uses silicon planar epitaxial technology, achieves 250 mW total power dissipation on FR4 PCB, and maintains junction temperature up to 150 °C. Thermal resistance from junction-to-ambient is 500 K/W under standard mounting conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884-B5V6 | Same 5.6 V nominal, ±2 %, but in larger SOD323 package (1.7 × 1.3 mm); 500 mW Ptot | Higher power handling, less board-space efficient - suited for prototyping or higher-current bias rails | Select when thermal margin >250 mW is required and PCB area permits larger footprint |
| MMSZ5232B | 5.6 V, ±5 % tolerance; SOD-123 package; 500 mW rating; 1000 Ω rdiff at 20 mA | Looser tolerance and higher dynamic impedance - acceptable for non-critical digital supply monitoring | Choose for cost-sensitive consumer applications where ±5 % regulation suffices and 1000 Ω impedance is tolerable |
Compared with BZX8850-B5V6YL, BZX884-B5V6 offers greater thermal headroom in a larger package, while MMSZ5232B trades precision and low-impedance performance for cost and legacy footprint compatibility - making BZX8850-B5V6YL optimal for space- and accuracy-constrained battery-powered systems.

FAQ
What is the maximum reverse voltage before breakdown for BZX8850-B5V6YL?
The BZX8850-B5V6YL exhibits a nominal Zener voltage of 5.6 V at 50 µA test current, with guaranteed minimum and maximum values of 5.49 V and 5.71 V respectively. Breakdown occurs sharply within this band; operation above 5.71 V at rated current is not specified and may exceed safe operating limits.
Can BZX8850-B5V6YL be used in parallel for higher current capability?
No - Zener diodes exhibit manufacturing variance in VZ, causing current hogging when paralleled. Even matched units risk thermal runaway due to positive temperature coefficient of dynamic resistance. For higher current, use a single higher-rated Zener or active regulation instead.
Is the SOD882 package compatible with standard reflow profiles?
Yes - the SOD882 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260 °C, 30 s max). Recommended solder land pattern matches Figure 10 in the datasheet: 0.6 mm × 0.3 mm pads with 0.7 mm center-to-center spacing.
How does the −2.0 mV/K temperature coefficient affect long-term accuracy?
A −2.0 mV/K coefficient means the Zener voltage decreases by 2 mV per Kelvin rise in junction temperature. Over a 100 K range (−25 °C to +75 °C), this introduces up to 200 mV drift - approximately ±3.6 % of 5.6 V. System-level compensation or calibration is advised for applications demanding <±1 % total error.
