Product details
Overview
BZX8850-B6V2YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 6.2 V nominal with ±2 % tolerance. It delivers 160 Ω differential resistance at 5 mA, operates at 50 μA test current, and supports stable biasing in portable battery-powered circuits requiring minimal leakage and low power dissipation (250 mW).
For engineers reviewing the BZX8850-B6V2YL datasheet, BZX8850-B6V2YL pinout, BZX8850-B6V2YL application, or BZX8850-B6V2YL equivalent, this device is selected for ultra-low-current reference and clamping functions where thermal efficiency, compact footprint, and tight voltage tolerance are critical in space-constrained embedded systems.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified nominal Zener voltage of 6.2 V at IZ = 50 μA, exhibiting a positive temperature coefficient of +0.4 mV/K and low junction capacitance of 110 pF at 0 V. Its differential resistance drops to 10 Ω at 5 mA, enabling stable regulation under light-load conditions.
The device uses a planar epitaxial silicon process and features cathode-marked top-side identification. It is rated for junction temperatures up to 150 °C and ambient operating range from −55 °C to +150 °C, with thermal resistance Rth(j-a) = 500 K/W on FR4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.08 V to 6.32 V at IZ = 50 μA - ensures precise 6.2 V reference under ultra-low bias |
| Tolerance | ±2 % - enables high-accuracy voltage clamping without external trimming |
| Differential Resistance (rdiff) | 160 Ω max at IZ = 50 μA; 10 Ω max at IZ = 5 mA - maintains regulation stability across load variations |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - supports continuous operation in thermally limited PCB layouts |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - limits conduction loss during forward-biased transient events |
| Reverse Leakage (IR) | 1.0 μA max at VR = 5 V - minimizes standby current in battery-critical applications |
| Junction Temperature (Tj) | 150 °C max - allows reliable operation in high-temperature industrial environments |

Key Features
| Feature | Design Value |
|---|---|
| Ultra-low test current | Specified at 50 μA - enables use in microamp-level bias networks without loading error |
| Tight voltage tolerance | ±2 % (B-series) - reduces need for post-layout calibration in precision analog references |
| Low thermal resistance | Rth(j-a) = 500 K/W - sustains 250 mW dissipation on standard FR4 with single-sided copper |
| Optimized noise profile | Intentional minor leakage rise per AN90031 - improves switching transients and reduces broadband noise in signal-path clamping |
| Miniature footprint | DFN1006-2 (1.0 × 0.6 mm) - saves board area in wearables, IoT sensors, and multi-rail PMIC monitoring |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX8850-C6V2 | ±5 % tolerance; higher leakage (0.1 µA at 5 V); same package and VZ range | Acceptable where cost sensitivity outweighs precision; less suitable for µA-bias analog references | Select when tighter tolerance is unnecessary and BOM cost reduction is prioritized over reference accuracy |
| MMSZ5234B | SOD-123 package (2.7 × 1.6 mm); ±5 % tolerance; 500 mW Ptot; 100 Ω rdiff at 20 mA | Higher power handling but larger footprint; better for medium-current regulation, not ultra-low-IQ designs | Choose only if board layout permits larger package and system requires >250 mW continuous dissipation |
Compared with BZX8850-C6V2, the BZX8850-B6V2YL offers 2.5× tighter voltage control and lower leakage-critical for battery life and ADC accuracy-while MMSZ5234B trades miniaturization for thermal headroom, making it unsuitable for space-constrained, low-IQ applications.

FAQ
What is the maximum reverse voltage before breakdown for BZX8850-B6V2YL?
The BZX8850-B6V2YL exhibits a nominal Zener voltage of 6.2 V, with guaranteed breakdown occurring between 6.08 V and 6.32 V at IZ = 50 μA. Below 6.08 V, reverse leakage remains ≤1.0 μA at 5 V; no hard "maximum reverse voltage" is defined outside its specified operating range.
Can BZX8850-B6V2YL be used in place of a 6.3 V Zener diode?
No-BZX8850-B6V2YL is strictly rated for 6.2 V nominal (6.08–6.32 V). Substituting for a 6.3 V part introduces up to 160 mV systematic offset, potentially violating regulation margins in precision feedback loops or reference circuits requiring exact 6.3 V thresholds.
Does this Zener diode require a series resistor in all applications?
Yes-a current-limiting resistor is mandatory to restrict Zener current within safe bounds. For example, at 12 V supply and 6.2 V regulation, a minimum 11.6 kΩ resistor limits IZ to 500 μA, staying below Ptot = 250 mW and preventing thermal runaway.
Is the SOD882 package compatible with standard reflow soldering profiles?
Yes-the DFN1006-2 (SOD882) package is qualified for lead-free reflow per J-STD-020. Recommended profile includes peak temperature ≤260 °C, time above 217 °C ≤60 seconds, and ramp rate ≤3 °C/s; solder land pattern matches Figure 10 in the datasheet.
