Product details
Overview
BZX384-C2V4,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 2.4 V nominal breakdown voltage at 5 mA, 300 mW total power dissipation, and 40 W non-repetitive peak reverse power. It serves as a precision reference or overvoltage clamp in low-power analog supply rails, sensor biasing circuits, and microcontroller reset supervision.
For engineers reviewing the BZX384-C2V4,115 datasheet, BZX384-C2V4,115 pinout, BZX384-C2V4,115 application, or BZX384-C2V4,115 equivalent, key selection criteria include its 2.2–2.6 V Zener voltage range, 600 Ω max differential resistance at 5 mA, 100 μA max reverse current at 1 V, -3.5 to 0.0 mV/K temperature coefficient, and SOD323 thermal resistance of 415 K/W in free air.
Technical Context
This device operates in reverse-bias breakdown mode with a specified Zener voltage of 2.4 V ±5 % at IZ = 5 mA. Its differential resistance remains ≤600 Ω under regulation, ensuring stable reference performance across load variations.
The diode exhibits a negative-to-zero temperature coefficient (−3.5 to 0.0 mV/K), minimizing drift in ambient temperature ranges from −65 °C to +150 °C. It supports pulsed operation up to 40 W (100 μs, square wave) without degradation when junction temperature stays below 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.2 V to 2.6 V at IZ = 5 mA - defines regulation threshold for low-voltage reference applications |
| Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - limits continuous DC power handling on standard FR4 PCB |
| Differential Resistance (rdif) | ≤600 Ω at IZ = 5 mA - determines output impedance and regulation stiffness under load change |
| Reverse Current (IR) | ≤100 μA at VR = 1 V - ensures low leakage before breakdown onset |
| Temperature Coefficient (SZ) | −3.5 to 0.0 mV/K - quantifies voltage drift per degree Celsius over operating junction temperature |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 μs - enables transient surge clamping without failure |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - confirms low conduction loss in forward-biased protection configurations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B2V4,115 | ±2 % tolerance (2.35–2.45 V), lower rdif (≤600 Ω), same package and Ptot | Better initial accuracy for tighter reference needs; identical thermal and surge specs | Select when higher initial precision is required without changing layout or thermal design |
| MMSZ4678T1G | 2.4 V ±5 %, SOD-123 package, 500 mW Ptot, 30 Ω rdif, higher power but larger footprint | Higher continuous power and lower impedance, but requires PCB redesign | Choose for higher-current regulation where board space allows SOD-123 and improved regulation stiffness is critical |
Compared with BZX384-C2V4,115, the BZX384-B2V4,115 offers tighter voltage tolerance at identical form factor and power, while MMSZ4678T1G trades increased size for significantly lower dynamic impedance and doubled power handling-making it suitable for higher-load or more demanding stability requirements.

FAQ
What is the maximum continuous reverse current this diode can sustain?
The BZX384-C2V4,115 has no defined maximum continuous reverse current; its regulation behavior is specified at IZ = 5 mA. Continuous operation above 5 mA must remain within the 300 mW total power limit, yielding a practical upper bound of ~125 mA at 2.4 V - but derating is required above 25 °C ambient due to thermal resistance of 415 K/W.
Can this Zener be used in forward-bias as a regular diode?
Yes - its forward voltage is ≤0.9 V at 10 mA, matching typical silicon diode behavior. However, it is not optimized for forward conduction: no guaranteed fast recovery, soft recovery characteristics, or surge current rating in forward mode. Use only for low-speed, low-current clamping or indicator functions where Zener-specific parameters are irrelevant.
How does the ±5 % tolerance affect circuit accuracy in a 2.4 V reference design?
The ±5 % tolerance means the actual Zener voltage falls between 2.20 V and 2.60 V at 5 mA. In a reference design, this introduces up to ±8.3 % error relative to nominal 2.4 V. For higher accuracy, system-level calibration or selection binning (e.g., BZX384-B2V4) is required - the C-grade part targets cost-sensitive applications where post-calibration or wide tolerance bands are acceptable.
Is this device qualified for automotive applications?
No - the BZX384-C2V4,115 is explicitly marked as non-automotive qualified in the datasheet revision history. Nexperia offers separate -Q automotive-qualified variants (e.g., BZX384-Q series) with AEC-Q200 stress testing, extended temperature validation, and PPAP documentation. This part is intended for industrial, consumer, and commercial equipment only.
