Product details
Overview
BZX384-C8V2,115 from Nexperia is a Zener voltage regulator diode in SOD323 (SC-76) package, providing 8.2 V nominal breakdown voltage with ±5 % tolerance at 5 mA test current, 80 Ω max differential resistance, and 0.7 μA max reverse leakage at 6.56 V. It delivers precision low-power regulation in space-constrained consumer and industrial power rails.
For engineers reviewing the BZX384-C8V2,115 datasheet, BZX384-C8V2,115 pinout, BZX384-C8V2,115 application, or BZX384-C8V2,115 equivalent, key selection criteria include its 8.2 V Zener voltage tolerance, thermal resistance (Rth(j-a) = 415 K/W), non-repetitive peak reverse power (40 W), cathode-anode polarity marking, and SOD323 footprint compatibility.
Technical Context
This discrete Zener diode operates in reverse-biased breakdown mode to clamp or regulate voltage across load circuits. Its 8.2 V nominal Zener voltage is specified at IZ = 5 mA with temperature coefficient of +3.2 mV/K, enabling stable reference generation over ambient ranges from –65 °C to +150 °C.
The device supports pulsed operation up to 40 W for ≤100 μs with Tj ≤ 150 °C, and maintains ≤300 mW steady-state dissipation on FR4 PCB with single-sided copper. Its 150 pF capacitance at 1 MHz and 0.9 V forward voltage at 10 mA support fast transient response and low-loss biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.7 V to 8.7 V at IZ = 5 mA - defines regulation band for precision 8.2 V reference applications |
| Differential Resistance (rdif) | ≤80 Ω - ensures minimal output voltage shift under load current variation |
| Reverse Leakage (IR) | ≤0.7 μA at VR = 6.56 V - guarantees low quiescent current in standby circuits |
| Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard PCB |
| Non-repetitive Peak Power | 40 W for tp ≤ 100 μs - enables robust surge suppression in transient-prone interfaces |
| Thermal Resistance (Rth(j-a)) | 415 K/W - determines junction-to-ambient temperature rise per watt on FR4 board |
| Forward Voltage (VF) | 0.9 V at IF = 10 mA - defines conduction loss when used in forward-biased protection paths |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-terminal, 1.35 mm × 0.85 mm body, 0.45 mm height, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; reverse-bias anode-to-cathode voltage establishes Zener breakdown |
| 2 | Anode (A) | Connected to ground or lower-potential rail; polarity must be observed to avoid forward conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective voltage clamping where tight regulation is not required, e.g., overvoltage protection thresholds |
| Low 80 Ω dynamic impedance | Maintains <100 mV output deviation across 1–10 mA load current changes in reference supply designs |
| 40 W non-repetitive surge rating | Withstands ESD and lightning-induced transients without degradation when used with series current limiting |
| 150 °C maximum junction temperature | Supports operation in high-temperature environments such as automotive cabin electronics and industrial motor controls |
| SOD323 footprint compatibility | Matches industry-standard 0805-equivalent land pattern, enabling drop-in replacement in dense PCB layouts |
Applications
| Overvoltage Protection | Reference Voltage Source |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5231BS-7-F | 8.2 V ±5 %, SOT-23 package, 200 mW Ptot, 100 Ω rdif | Larger footprint and higher dynamic impedance reduce regulation precision in low-current references | Select when existing SOT-23 layout prohibits SOD323 rework and 300 mW headroom is not required |
| BZX384-B8V2,115 | 8.2 V ±2 %, identical SOD323 package, same 300 mW rating, 150 Ω rdif | Tighter tolerance improves reference accuracy but increases cost and reduces availability in high-volume production | Choose when system-level calibration requires <±0.16 V Zener variation and budget allows premium grade |
Compared with BZX384-C8V2,115, MMBZ5231BS-7-F trades package compatibility and power capability for lower cost in legacy designs, while BZX384-B8V2,115 sacrifices surge margin and impedance performance for tighter voltage control-making the C-grade optimal for general-purpose clamping where cost, size, and pulse robustness are prioritized.

FAQ
What is the maximum continuous power dissipation for BZX384-C8V2,115?
The BZX384-C8V2,115 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 is required above 25 °C at 2.4 mW/°C based on Rth(j-a) = 415 K/W.
How is polarity identified on the BZX384-C8V2,115 package?
The cathode terminal (Pin 1) is marked by a visible bar on the top surface of the SOD323 package. The anode (Pin 2) is unmarked and located opposite the bar. This marking aligns with the graphic symbol in Nexperia's datasheet Figure 2 and must be verified during placement to prevent reverse-bias failure.
Can BZX384-C8V2,115 be used for ESD protection?
Yes-its 40 W non-repetitive peak reverse power rating at tp ≤ 100 μs makes it suitable for low-energy ESD clamping when paired with appropriate series impedance (e.g., 100 Ω resistor). It is not rated for IEC 61000-4-2 contact discharge but provides effective board-level transient suppression in conjunction with TVS diodes.
What is the typical temperature coefficient for this Zener voltage?
At IZ = 5 mA, the BZX384-C8V2,115 exhibits a temperature coefficient of +3.2 mV/K, meaning its Zener voltage increases by approximately 3.2 mV per degree Celsius rise in junction temperature. This positive drift helps offset negative coefficients in associated circuitry like op-amps or resistors.
