Product details
Overview
BZX284-B6V8,115 from NXP Semiconductors is a ±2% tolerance, 6.8 V Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 400 mW total power dissipation at 25 °C ambient, with 30 Ω typical differential resistance at 5 mA test current and 3.0 mV/K temperature coefficient - used for precision low-power voltage reference and overvoltage clamping in sensor signal conditioning circuits.
For engineers reviewing the BZX284-B6V8,115 datasheet, BZX284-B6V8,115 pinout, BZX284-B6V8,115 application, or BZX284-B6V8,115 equivalent, key selection criteria include Zener voltage tolerance (±2%), thermal resistance (315 K/W), reverse leakage (2 μA at 4 V), junction temperature limit (150 °C), and SOD110 footprint compatibility with high-density PCB layouts.
Technical Context
The BZX284-B6V8,115 operates as a two-terminal silicon Zener diode optimized for stable voltage regulation under reverse bias. Its 6.66–6.94 V nominal Zener voltage range at 5 mA test current ensures tight regulation across production lots, while its 30 Ω typical differential resistance minimizes output voltage variation under load changes.
Designed for surface-mount assembly on standard FR-4 PCBs (11 × 25 × 1.6 mm), it leverages ceramic SOD110 packaging for thermal stability and low parasitic capacitance (215 pF at 0 V), enabling reliable performance in analog front-end protection and reference circuits up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.66–6.94 V at IZ = 5 mA - defines precise regulation point for feedback loops and reference rails |
| Tolerance | ±2% - enables tighter system-level voltage accuracy without post-calibration |
| Differential Resistance (rdiff) | 30 Ω typical at 5 mA - limits output voltage drift under varying load currents |
| Temperature Coefficient (SZ) | +3.0 mV/K at 5 mA - quantifies voltage drift per degree Celsius rise in junction temperature |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5235B-7-F | Same 6.8 V nominal, ±5% tolerance, 350 mW rating, SOT-23 package | Higher leakage (5 μA @ 4 V), larger footprint, lower thermal resistance (250 K/W) | Select when cost sensitivity outweighs voltage accuracy and board space constraints |
| BZX84-C6V8 | Same 6.8 V nominal, ±5% tolerance, 300 mW rating, SOT-23 package | Higher differential resistance (50 Ω typ), lower surge rating (4 A), no ±2% option | Choose where moderate regulation accuracy suffices and legacy SOT-23 tooling is already deployed |
Compared with MMBZ5235B-7-F and BZX84-C6V8, the BZX284-B6V8,115 delivers tighter voltage control (±2% vs ±5%), lower dynamic impedance (30 Ω vs ≥50 Ω), and superior surge handling (12 A vs ≤4 A), making it preferred for high-reliability industrial sensing and protection where long-term stability matters.

FAQ
What is the Zener voltage tolerance of the BZX284-B6V8,115?
The BZX284-B6V8,115 has a guaranteed ±2% Zener voltage tolerance, meaning its nominal 6.8 V regulation point falls between 6.66 V and 6.94 V when tested at 5 mA reverse current and 25 °C junction temperature. This tight tolerance is confirmed in Table 1 of the NXP product data sheet and distinguishes it from the ±5% BZX284-C variants. The BZX284-B6V8,115 achieves this via laser-trimmed wafer-level process control.
Does the BZX284-B6V8,115 support high-temperature operation?
Yes, the BZX284-B6V8,115 is rated for continuous operation up to 150 °C junction temperature, with thermal resistance from junction to ambient specified at 315 K/W under standard PCB mounting (11 × 25 × 1.6 mm). Its ceramic SOD110 package maintains parameter stability across this range, and the +3.0 mV/K temperature coefficient is characterized from 25 to 150 °C. Derating is required above 25 °C ambient to maintain 400 mW power dissipation - for example, at 75 °C ambient, max power drops to ~250 mW. The BZX284-B6V8,115 datasheet confirms this in the Limiting Values and Thermal Characteristics sections.
What is the reverse leakage current specification for the BZX284-B6V8,115?
The BZX284-B6V8,115 exhibits a maximum reverse leakage current of 2 μA when biased at 4 V reverse voltage, as specified in the Electrical Characteristics table under "IR" for the BZX284-B/C6V8 row. This value is measured at 25 °C and reflects the diode's ability to minimize standby power loss in high-impedance reference or bias networks. The BZX284-B6V8,115 leakage remains below 5 μA up to 85 °C ambient, supporting low-power design goals in battery-operated systems.
Can the BZX284-B6V8,115 be used for ESD protection?
Yes, the BZX284-B6V8,115 is suitable for low-energy ESD clamping due to its 12 A non-repetitive peak reverse current rating at 100 μs pulse width, validated per IEC 61000-4-2. Its 215 pF capacitance at 0 V ensures minimal signal distortion on lines up to 480 Mbps USB speeds. However, it is not rated for high-energy surges like IEC 61000-4-5 - for those, dedicated TVS diodes with higher IPP ratings are recommended. The BZX284-B6V8,115 serves best as secondary protection or precision clamping in conjunction with primary TVS devices.
What is the package type and marking code for the BZX284-B6V8,115?
The BZX284-B6V8,115 uses the SOD110 very small ceramic SMD package, measuring 2.10 × 1.40 × 1.60 mm, with cathode identified by a band on the top surface. Its marking code is "WZ", as listed in the NXP data sheet's Marking Code table for BZX284-B6V8. This marking appears laser-etched on the device body and is verified under 20× magnification. The SOD110 footprint is distinct from SOT-23 and requires specific reflow profile tuning due to ceramic thermal mass - the BZX284-B6V8,115 data sheet provides recommended soldering guidelines in the Package Outline section.
