Product details
Overview
BZX8850-C6V8YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 6.8 V nominal with ±5 % tolerance, 80 Ω differential resistance at 5 mA, and 5.1 mV/K temperature coefficient. It operates at 50 μA test current, enabling ultra-low-power biasing in portable battery-powered circuits such as sensor reference rails and microcontroller reset supervisors.
For engineers reviewing the BZX8850-C6V8YL datasheet, BZX8850-C6V8YL pinout, BZX8850-C6V8YL application, or BZX8850-C6V8YL equivalent, this device is selected for stable low-current regulation where thermal drift, leakage control, and ultra-small footprint are critical-especially in space-constrained IoT nodes and wearables.
Technical Context
This Zener diode delivers regulated 6.8 V output under reverse-bias conditions with specified performance at IZ = 50 μA, 1 mA, and 5 mA test currents. Its differential resistance of 80 Ω at 5 mA ensures tight voltage stability across load variations, while its 1.2 mV/K positive temperature coefficient minimizes drift over −55 °C to +150 °C ambient range.
The device uses an intentional minor rise in leakage current per AN90031 to reduce switching noise and improve transient response in low-power analog references. Its 100 pF capacitance at 0 V and 1 MHz supports high-frequency decoupling without compromising regulation fidelity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage VZ | 6.46 V to 7.14 V at IZ = 5 mA - defines usable regulation band for 6.8 V nominal rail |
| Differential resistance rdiff | 80 Ω at IZ = 5 mA - determines output impedance and load regulation error |
| Temperature coefficient SZ | +1.2 mV/K - quantifies voltage drift per degree Celsius, enabling thermal error budgeting |
| Reverse current IR | ≤ 0.1 µA at VR = 5.1 V - ensures minimal quiescent power draw in standby mode |
| Forward voltage VF | ≤ 0.9 V at IF = 10 mA - supports low-loss forward conduction during fault or startup |
| Total power dissipation Ptot | 250 mW at Tamb ≤ 25 °C - sets maximum continuous power handling on standard FR4 PCB |
| Junction-to-ambient Rth(j-a) | 500 K/W - informs thermal rise under sustained bias, critical for derating in sealed enclosures |
Pinout & Package
Package: SOD882 (DFN1006-2), leadless ultra-small surface-mount plastic package; dimensions 1.0 × 0.6 × 0.5 mm; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity must be observed for correct Zener breakdown operation |

Key Features
| Feature | Design Value |
|---|---|
| Ultra-low test current operation | Specified at 50 μA - enables use in nanoamp-level bias networks without loading sensitive sources |
| Optimized leakage profile | Intentional minor leakage rise per AN90031 - reduces switching noise and improves transient settling in reference paths |
| Tight voltage tolerance | ±5 % at 6.8 V - balances cost and precision for non-critical regulation where 340 mV window is acceptable |
| Miniature DFN footprint | SOD882 (1.0 × 0.6 mm) - saves >70 % board area vs. traditional SOD-123, ideal for wearable PCBs |
| High thermal robustness | 150 °C max junction temperature - supports operation in thermally aggressive environments like enclosed sensors |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8850-B6V8 | ±2 % tolerance (6.66–6.94 V), 160 Ω rdiff at 5 mA, +0.4 mV/K tempco | Narrower voltage window but higher dynamic impedance and lower thermal drift | Select when tighter regulation accuracy outweighs need for lowest noise or lowest power consumption |
| MMSZ4687T1G | 6.8 V ±5 %, 100 Ω rdiff, SOD-123 package (2.7 × 1.4 mm), 500 mW Ptot | Larger footprint and higher power rating; no intentional leakage optimization | Choose when board space allows larger package and higher surge capability is required over ultra-low leakage |
Compared with BZX8850-C6V8YL, the BZX8850-B6V8 offers tighter tolerance but higher impedance and less optimized noise behavior, while the MMSZ4687T1G trades miniaturization and leakage control for ruggedness and thermal headroom-making the C6V8YL optimal for size- and power-constrained designs demanding low-noise regulation.

FAQ
What is the maximum reverse voltage before breakdown for BZX8850-C6V8YL?
The nominal Zener voltage is 6.8 V, with guaranteed breakdown occurring between 6.46 V and 7.14 V at 5 mA test current. The absolute maximum non-repetitive peak reverse voltage is not rated separately-the device is intended for continuous regulation within its specified VZ band and must not be subjected to sustained reverse voltages exceeding 7.14 V without current limiting.
Can BZX8850-C6V8YL be used in forward conduction mode?
Yes-it functions as a standard silicon diode in forward bias, with forward voltage ≤ 0.9 V at 10 mA. However, its primary design purpose is reverse-bias Zener regulation; forward conduction is only specified for fault condition analysis or dual-role circuit topologies-not for continuous rectification or signal steering.
How does the "intentional minor rise of leakage current" affect circuit performance?
This controlled leakage enhancement, documented in AN90031, reduces high-frequency noise and accelerates transient response during voltage step changes-particularly beneficial in analog reference paths where fast settling and low RMS noise are critical, without increasing steady-state power consumption beyond 0.1 µA at 5.1 V.
Is BZX8850-C6V8YL suitable for automotive applications?
No-this part is not AEC-Q200 qualified and lacks automotive-grade screening, temperature validation, or failure-in-time (FIT) data. Nexperia explicitly states non-automotive qualification in its legal disclaimers; use requires full customer validation for safety-critical or mission-critical vehicle systems.
