Product details
Overview
BZX8850-C6V2YL 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 fast transient response.
For engineers reviewing the BZX8850-C6V2YL datasheet, BZX8850-C6V2YL pinout, BZX8850-C6V2YL application, or BZX8850-C6V2YL equivalent, this device serves as a compact, low-power voltage reference for sensor biasing, ADC reference stabilization, and microcontroller reset circuitry where space and quiescent current are critical constraints.
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 temperature coefficient of +0.4 mV/K and differential resistance of 160 Ω at 5 mA. Its ultra-low test current enables operation in sub-100 μA bias networks without compromising regulation accuracy.
The device features intentional minor leakage optimization per AN90031 to reduce noise and improve switching speed in low-power analog signal conditioning paths. Its DFN1006-2 package provides thermal resistance of 500 K/W (junction-to-ambient, FR4 PCB), limiting power dissipation to 250 mW at Tamb ≤ 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.89 V to 6.51 V at IZ = 50 μA - tight ±2 % tolerance ensures predictable clamping in low-current references |
| Differential Resistance rdiff | 160 Ω at IZ = 5 mA - defines regulation stiffness under small-signal load variations |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - enables use as bidirectional clamp or polarity protection element |
| Total Power Dissipation Ptot | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC power in standard FR4 layout |
| Junction Temperature Tj | −55 °C to +150 °C - supports operation across industrial ambient ranges with derating |
| Reverse Current IR | ≤ 1.0 μA at VR = 5 V - confirms low leakage for battery-critical standby modes |
| Diode Capacitance Cd | 110 pF at VR = 0 V, f = 1 MHz - impacts high-frequency noise filtering and transient response |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234B (ON Semiconductor) | Same 6.2 V nominal, ±5 % tolerance, 200 mW rating, SOT-23 package (2.9 × 1.3 mm) | Larger footprint and looser tolerance increase board area and require tighter system calibration | Select when legacy SOT-23 reflow compatibility is mandatory and ±5 % regulation error is acceptable |
| BZX84-C6V2 (Nexperia) | Same 6.2 V nominal, ±5 % tolerance, 350 mW rating, SOT-23 package | Higher power rating but larger size and higher leakage (>5 μA at 5 V) degrade battery life | Choose only if >250 mW dissipation is needed and space constraints allow SOT-23 mounting |
Compared with MMBZ5234B and BZX84-C6V2, BZX8850-C6V2YL offers 42 % smaller footprint, ±2 % tolerance for improved system accuracy, and 5× lower leakage-making it optimal for space-constrained, long-life battery applications where regulation precision and standby current dominate selection criteria.

FAQ
What is the maximum continuous reverse power dissipation for BZX8850-C6V2YL?
The maximum continuous reverse power dissipation is 250 mW at ambient temperature ≤25 °C on a standard FR4 PCB with single-sided copper. Derating is required above 25 °C at 2.0 mW/°C based on thermal resistance of 500 K/W, ensuring safe operation up to 150 °C junction temperature.
How does the ±2 % tolerance affect circuit accuracy in a 6.2 V reference design?
The ±2 % tolerance means the actual Zener voltage falls between 5.89 V and 6.51 V at 50 μA. In a typical 12-bit ADC reference application, this introduces ≤0.8 LSB full-scale error, which can be calibrated out in firmware or compensated using a matched resistor divider-no additional hardware is required.
Can BZX8850-C6V2YL be used in forward conduction mode?
Yes-it exhibits ≤0.9 V forward voltage at 10 mA, making it suitable for polarity protection or low-drop rectification in ultra-low-power paths. However, its primary design intent is reverse-bias Zener operation; forward characteristics are secondary and not optimized for high-current switching.
Is the DFN1006-2 package compatible with standard reflow soldering profiles?
Yes-the device is qualified for JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260 °C, 30 seconds). The recommended solder land pattern (0.6 mm pad length, 0.3 mm width, 0.7 mm spacing) is documented in Figure 10 of the datasheet.
