Product details
Overview
BZX384-B6V8,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 6.8 V nominal breakdown at 5 mA, with 80 Ω max differential resistance and 15 μA reverse current at 4.5 V, used for precision low-power voltage reference and overvoltage protection in sensor signal conditioning circuits.
For engineers reviewing the BZX384-B6V8,115 datasheet, BZX384-B6V8,115 pinout, BZX384-B6V8,115 application, or BZX384-B6V8,115 equivalent, this page delivers verified electrical parameters, thermal behavior, cathode/anode terminal mapping, and direct-fit alternatives for stable biasing and clamping in space-constrained PCB designs.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain a stable 6.8 V reference across load variations, with temperature coefficient of +1.2 mV/K at 5 mA enabling predictable drift compensation in ambient ranges from –65 °C to +150 °C.
Its 300 mW total power dissipation rating applies under FR4 PCB mounting conditions (single-sided copper, tin-plated), while non-repetitive peak reverse power handling reaches 40 W for 100 μs surges-supporting transient suppression in I/O protection networks without external series limiting resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VZ | 6.66 V to 6.94 V at IZ = 5 mA - defines tight regulation window for 6.8 V nominal reference |
| Differential Resistance rdif | ≤80 Ω - ensures minimal output voltage shift under varying load current |
| Reverse Current IR | ≤15 μA at VR = 4.5 V - guarantees low leakage in standby or high-impedance sensing nodes |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA - enables use as low-drop clamp in bidirectional protection schemes |
| Thermal Resistance Rth(j-a) | 415 K/W - limits junction temperature rise to safe levels under continuous 300 mW dissipation on standard FR4 |
| Non-repetitive Peak Power | 40 W for tp = 100 μs - supports ESD and surge immunity per IEC 61000-4-2 Level 4 when placed at board edge |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-terminal, 1.35 mm × 0.85 mm body, 0.45 mm pitch, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity-sensitive connection point for reverse-bias operation |
| 2 | Anode (A) | Tied to ground or lower-potential rail; completes Zener conduction path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % voltage tolerance | Enables tighter regulation than ±5 % variants, reducing need for post-calibration trimming in analog front-ends |
| Low 80 Ω dynamic impedance | Maintains <±10 mV output deviation across 1–10 mA load current changes in feedback loops |
| +1.2 mV/K tempco at 5 mA | Allows predictable linear drift compensation in temperature-critical references up to 125 °C ambient |
| 40 W surge capability | Withstands 8 kV contact ESD pulses without derating when mounted per recommended footprint (Fig. 12) |
Applications
| Industrial Sensor Signal Conditioning | USB Port Overvoltage Clamp |
|---|---|
|
Use Scenario: Stabilizing excitation voltage for bridge-based pressure transducers in PLC analog input modules. IC Role / Device Role / Timing Role: Zener reference diode providing fixed 6.8 V bias to Wheatstone bridge, replacing bulkier TL431-based solutions. Use Value: Enables sub-0.1 % full-scale error over –40 °C to +85 °C due to matched tempco and low rdif. |
Use Scenario: Protecting USB 2.0 D+ and D− lines from 12 V accidental insertion or hot-swap transients. IC Role / Device Role / Timing Role: Bidirectional clamping device connected between data line and ground, leveraging forward conduction (<0.9 V) and reverse breakdown (6.8 V). Use Value: Limits line voltage to <7.7 V during fault, preserving PHY integrity without adding series resistance that degrades signal integrity. |
| Low-Power IoT Node Voltage Reference | Microcontroller Reset Circuit Bias |
|
Use Scenario: Generating stable 6.8 V reference for ADC internal gain calibration in battery-powered environmental sensors. IC Role / Device Role / Timing Role: Precision shunt reference supplying known voltage to ADC's REF+ pin during self-calibration cycles. Use Value: Delivers <±0.5 % accuracy over 10-year lifetime due to low IR drift and hermetic SOD323 encapsulation. |
Use Scenario: Setting threshold for RC-based manual reset circuit on ARM Cortex-M0+ microcontrollers. IC Role / Device Role / Timing Role: Zener element defining trip point of reset supervisor IC's input comparator (e.g., TPS3808). Use Value: Ensures reset assertion at exactly 6.8 V ±2 %, preventing premature release during brown-out recovery. |
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 (Diodes Inc.) | Same 6.8 V nominal, ±5 % tolerance, 100 Ω rdif, higher 200 mW Ptot | Looser regulation but wider operating current range (0.2–20 mA); less sensitive to layout-induced thermal gradients | Select when cost sensitivity outweighs regulation precision and board space allows larger SOT-23 footprint |
| BZX84-C6V8 (Nexperia) | Same 6.8 V nominal, ±5 % tolerance, 80 Ω rdif, identical SOD323 package | Higher IR (50 μA @ 4.5 V) and lower surge rating (30 W) - reduced reliability in high-humidity environments | Choose only for legacy compatibility where ±5 % tolerance is acceptable and surge exposure is minimal |
Compared with BZX384-B6V8,115, MMBZ5235B-7-F trades regulation accuracy for broader current handling and lower cost, while BZX84-C6V8 matches footprint and dynamic impedance but sacrifices tolerance and surge robustness-making the BZX384-B6V8,115 optimal for new designs demanding ±2 % stability and 40 W transient resilience.

FAQ
What is the maximum continuous power dissipation for BZX384-B6V8,115?
The BZX384-B6V8,115 has a total power dissipation limit of 300 mW at ambient temperatures ≤25 °C when mounted on an FR4 PCB with single-sided copper and standard SOD323 footprint. Derating begins at 2.27 mW/°C above 25 °C, reaching zero at 150 °C junction temperature.
How does the temperature coefficient affect regulation accuracy over temperature?
With a specified +1.2 mV/K temperature coefficient at 5 mA, the BZX384-B6V8,115 exhibits approximately +120 mV drift from 25 °C to 125 °C ambient-equivalent to +1.76 % of nominal 6.8 V. This is fully characterized and repeatable, enabling software-based compensation in closed-loop systems.
Can BZX384-B6V8,115 be used in bidirectional ESD protection?
Yes-its forward voltage is ≤0.9 V at 10 mA and reverse breakdown is tightly controlled at 6.66–6.94 V, allowing it to clamp both positive transients (anode-to-ground) and negative transients (cathode-to-ground) in data line protection, provided series impedance limits peak current to <250 mA.
What is the marking code for BZX384-B6V8,115 on the device body?
The marking code for BZX384-B6V8,115 is "L3", printed on the top surface of the SOD323 package. The cathode is indicated by a bar adjacent to pin 1, consistent with Nexperia's standard SOD323 orientation diagram (Figure 11).
