Product details
Overview
BZX384-C6V2,115 from Nexperia is a 6.2 V ±5 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 300 mW total power dissipation at 25 °C ambient, with 150 Ω typical differential resistance at 5 mA and 10 μA reverse current at 4.96 V. It serves as a precision low-power reference or clamp in power supply feedback paths, sensor biasing circuits, and overvoltage protection stages.
For engineers reviewing the BZX384-C6V2,115 datasheet, BZX384-C6V2,115 pinout, BZX384-C6V2,115 application, or BZX384-C6V2,115 equivalent, this page delivers verified Zener voltage, thermal resistance, temperature coefficient, non-repetitive surge capability, and cathode/anode terminal mapping - all confirmed from Nexperia's Rev. 4 product data sheet.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable 6.2 V regulation across load and line variations. Its ±5 % tolerance (BZX384-C series), 0.4 mV/K temperature coefficient at 5 mA, and 150 Ω dynamic impedance define its accuracy and stability under varying thermal and current conditions.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it supports pulsed reverse power up to 40 W (100 μs, square wave) and junction temperatures up to 150 °C. Thermal resistance from junction to ambient is 415 K/W in free air, limiting continuous dissipation without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal, 5.8 V–6.6 V min/max range at IZ = 5 mA - defines regulation setpoint and tolerance band for feedback or clamping. |
| Differential Resistance (rdif) | 150 Ω max at IZ = 5 mA - determines output voltage deviation under load current changes. |
| Reverse Current (IR) | 10 μA max at VR = 4.96 V - specifies leakage level below breakdown, critical for low-power standby circuits. |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C on standard FR4 PCB - sets maximum continuous DC power handling without derating. |
| Non-repetitive Peak Reverse Power | 40 W for tp = 100 μs - enables transient overvoltage suppression in surge-prone interfaces. |
| Thermal Resistance (Rth(j-a)) | 415 K/W in free air - quantifies self-heating rise per watt, guiding layout and thermal margin analysis. |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - relevant for polarity-check or dual-function (Zener + rectifier) circuit reuse. |
Pinout & Package
The BZX384-C6V2,115 is housed in a SOD323 (SC-76) plastic surface-mount package measuring 1.8 mm × 1.35 mm × 0.95 mm, with cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs. |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for regulation. |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-optimized regulation where tight accuracy is not required, such as non-critical biasing or coarse clamping. |
| 300 mW power rating in SOD323 | Supports compact, low-profile designs without external heatsinking for <100 mA load currents. |
| 40 W non-repetitive surge capability | Provides transient immunity against ESD or inductive kickback without external TVS devices. |
| 150 °C maximum junction temperature | Allows operation in high-ambient industrial environments when mounted per standard FR4 footprint. |
| Cathode-bar marking | Ensures unambiguous polarity identification during automated placement and visual inspection. |
Applications
| Power Supply Feedback Reference | Sensor Biasing Network |
|---|---|
|
Use Scenario: Stabilizing the reference input of an optocoupler-based isolated DC-DC converter feedback loop. IC Role / Device Role / Timing Role: Zener diode provides fixed 6.2 V reference to TL431 or similar shunt regulator, setting output voltage via resistor divider. Use Value: Maintains ±5 % output regulation across line/load/temperature with no active components, reducing BOM count and failure modes. |
Use Scenario: Supplying stable bias voltage to analog output sensors (e.g., pressure transducers) operating from unregulated rails. IC Role / Device Role / Timing Role: Acts as a low-current, low-noise voltage clamp to establish sensor excitation potential independent of supply ripple. Use Value: Limits bias drift to <±0.4 mV/K, preserving sensor accuracy without requiring dedicated LDO or reference IC. |
| Overvoltage Clamp for MCU I/O | ESD Protection Pre-stage |
|
Use Scenario: Protecting 5 V-tolerant GPIO pins from accidental 12 V misconnection or inductive transients. IC Role / Device Role / Timing Role: Clamps voltage to ~6.2 V during overvoltage events, diverting excess current to ground before MCU damage threshold. Use Value: Absorbs up to 40 W peak surges (100 μs), preventing latch-up or gate oxide rupture while maintaining signal integrity during normal operation. |
Use Scenario: Front-end protection for USB or RS-485 receiver inputs exposed to system-level ESD events. IC Role / Device Role / Timing Role: Provides first-line voltage limiting ahead of dedicated TVS arrays, reducing stress on downstream protection elements. Use Value: Low 150 Ω dynamic impedance ensures fast response (<1 ns) and minimal overshoot during 8 kV HBM discharges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234BS-7-F | 6.2 V ±5 %, SOT-323 package, 225 mW Ptot, 170 Ω rdif | Lower power rating and higher impedance reduce regulation stability under varying loads. | Select when board space allows SOT-323 and thermal budget is tighter than 300 mW. |
| BZX384-B6V2,115 | 6.2 V ±2 %, same SOD323 package and 300 mW rating, 100 Ω rdif | Tighter tolerance and lower impedance improve accuracy in precision references but increase cost. | Choose for feedback loops requiring <±2 % output tolerance or <100 Ω dynamic impedance. |
Compared with BZX384-C6V2,115, MMBZ5234BS-7-F trades power and impedance performance for slightly smaller footprint, while BZX384-B6V2,115 delivers superior regulation accuracy and lower noise at identical thermal capability - enabling direct substitution only where tighter voltage control justifies higher unit cost.

FAQ
What is the maximum continuous reverse current for BZX384-C6V2,115 at 25 °C?
The device supports up to 250 mA forward current, but for Zener operation, the recommended continuous reverse current is limited by power dissipation: at 25 °C ambient, IZ must stay ≤48.4 mA to remain within 300 mW (6.2 V × 48.4 mA ≈ 300 mW). Derating applies above 25 °C per the thermal resistance curve.
Can BZX384-C6V2,115 be used in place of a 5.6 V Zener diode?
No - its nominal Zener voltage is 6.2 V with a guaranteed range of 5.8 V to 6.6 V. Substituting it for a 5.6 V part would shift regulation by >10 %, potentially causing overvoltage in feedback loops or incorrect biasing in analog circuits. Always match nominal VZ and tolerance class.
How does the ±5 % tolerance affect regulation accuracy in a 12 V supply feedback divider?
In a typical resistive divider feeding a TL431, a ±5 % VZ error propagates directly to output voltage error. For a 12 V target, ±5 % on 6.2 V introduces ±0.31 V offset at the reference node, resulting in ~±2.6 % output variation - acceptable for non-critical supplies but insufficient for <±1 % specifications.
Is BZX384-C6V2,115 qualified for automotive applications?
No - per Nexperia's Rev. 4 datasheet, the BZX384 series is non-automotive qualified. Automotive alternatives (e.g., BZX384-Q series) undergo additional AEC-Q200 stress testing and have separate qualification documentation. Use only the -Q variants in vehicle ECUs or ADAS modules.
