Product details
Overview
BZX8850-B6V8YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 6.8 V nominal with ±2 % tolerance. It delivers stable reference voltage under 50 μA test current, features 80 Ω differential resistance at 5 mA, and operates with 1.2 mV/K temperature coefficient - ideal for battery-powered sensor biasing and low-power analog signal conditioning.
For engineers reviewing the BZX8850-B6V8YL datasheet, BZX8850-B6V8YL pinout, BZX8850-B6V8YL application, or BZX8850-B6V8YL equivalent, this device is selected for ultra-small footprint voltage references requiring tight tolerance, low leakage (<0.1 µA at 5.1 V), and thermal stability in space-constrained portable electronics.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 6.8 V at IZ = 50 µA, maintaining regulation across 1–5 mA operating range. Its differential resistance of 80 Ω at 5 mA ensures minimal output voltage variation under load shifts.
The device exhibits a positive temperature coefficient of +1.2 mV/K, enabling predictable drift compensation in multi-diode reference networks. Its 100 pF capacitance at 0 V and 1 MHz supports stable performance in low-frequency feedback paths without parasitic oscillation risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.66 V to 6.94 V at IZ = 50 µA - defines precise regulation window for low-bias circuits |
| Tolerance | ±2 % - enables high-accuracy voltage references without external trimming |
| Differential Resistance rdiff | 80 Ω at IZ = 5 mA - limits output voltage shift to ≤0.4 V per 5 mA load change |
| Temperature Coefficient SZ | +1.2 mV/K - provides predictable +8.2 mV drift over −40 °C to +85 °C ambient |
| Reverse Leakage IR | <0.1 µA at VR = 5.1 V - minimizes quiescent current in always-on monitoring circuits |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA - ensures low-loss anode-cathode conduction during transient clamping |
| Total Power Dissipation Ptot | 250 mW at Tamb ≤ 25 °C - supports continuous operation in thermally unmanaged PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V8 | ±5 % tolerance, SOT23 package (3.0 × 1.4 mm), 100 Ω rdiff at 5 mA | Larger footprint; higher dynamic impedance increases reference error under load | Select when board space permits larger package and ±5 % accuracy suffices |
| MMSZ5235B | ±5 % tolerance, SOD-123 package (2.7 × 1.6 mm), 100 Ω rdiff, 100 pF Cd | Higher thermal resistance (625 K/W); less suitable for high-density thermal environments | Choose for legacy SOD-123 footprint compatibility where miniaturization is secondary |
Compared with BZX8850-B6V8YL, both alternatives trade tighter tolerance and smaller size for wider availability and lower cost - making them viable only where ±5 % regulation error and 2× larger PCB area are acceptable in the target design.

FAQ
What is the maximum reverse voltage before breakdown for BZX8850-B6V8YL?
The device enters controlled Zener breakdown at 6.66 V minimum and 6.94 V maximum when tested at 50 µA. It is not rated for sustained operation above 6.94 V in reverse bias - exceeding this risks irreversible avalanche damage due to localized thermal runaway.
Can BZX8850-B6V8YL be used in forward conduction mode?
Yes - it conducts with ≤0.9 V forward voltage at 10 mA, but its primary function is reverse-bias regulation. Forward use is limited to transient clamping or polarity protection; continuous forward current must stay below 200 mA per absolute maximum ratings.
How does the ±2 % tolerance affect circuit accuracy in a 6.8 V reference design?
At 25 °C, the actual Zener voltage falls between 6.66 V and 6.94 V. When combined with +1.2 mV/K temperature coefficient, worst-case drift over −40 °C to +85 °C adds ±0.15 V, resulting in total regulation window of 6.51 V to 7.09 V - sufficient for 1% system-level accuracy with margin.
Is the SOD882 package compatible with standard reflow soldering profiles?
Yes - the DFN1006-2 footprint matches IPC-7351B standard for 0201-size components. Recommended reflow uses peak temperature ≤260 °C for ≤10 seconds, with preheat ramp rate ≤3 °C/s and cooling rate ≥1 °C/s to prevent solder joint voiding or die cracking.
