Product details
Overview
BZX384-B2V4,115 from Nexperia is a ±2 % 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 low-power reference or clamp in voltage regulation, overvoltage protection, and signal conditioning circuits.
For engineers reviewing the BZX384-B2V4,115 datasheet, BZX384-B2V4,115 pinout, BZX384-B2V4,115 application, or BZX384-B2V4,115 equivalent, key selection criteria include its 2.4 V Zener voltage with ±2 % tolerance, 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 Zener diode operates in reverse-biased breakdown mode to maintain stable voltage across its terminals under varying load or supply conditions. Its 2.4 V nominal Zener voltage is specified at 5 mA test current, with differential resistance ≤600 Ω ensuring minimal voltage deviation under small-signal current changes.
The device features a negative-to-zero temperature coefficient (-3.5 to 0.0 mV/K), enabling predictable drift behavior in ambient temperature ranges from -65 °C to +150 °C. Its SOD323 package supports surface-mount reflow/wave soldering per JEDEC standards and delivers 110 K/W junction-to-solder-point thermal resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.35 V to 2.45 V at IZ = 5 mA - defines precise clamping threshold for low-voltage reference applications |
| Tolerance | ±2 % - ensures tight voltage matching across production lots without post-manufacture trimming |
| Differential Resistance (rdif) | ≤600 Ω at IZ = 5 mA - limits output voltage variation under dynamic load current changes |
| Reverse Current (IR) | ≤100 μA at VR = 1 V - guarantees low leakage in standby or high-impedance bias networks |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC power handling in standard layout |
| Non-repetitive Peak Reverse Power | 40 W for tp = 100 μs - enables transient surge suppression in ESD or inductive switching events |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - confirms low conduction loss when used in forward-biased protection paths |
Pinout & Package

Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|
|
Use Scenario: Stabilizing feedback voltage in low-current LDO regulators or adjustable DC-DC converters. IC Role / Device Role / Timing Role: Zener diode acts as shunt reference, sinking excess current to hold regulated output at 2.4 V ±2 %. Use Value: Enables accurate 2.4 V setpoint with <600 Ω dynamic impedance, minimizing load-induced output drift. |
Use Scenario: Protecting microcontroller I/O pins from voltage spikes exceeding 2.4 V during hot-plug or ESD events. IC Role / Device Role / Timing Role: Clamps transient excursions above 2.45 V by conducting reverse current into ground. Use Value: Limits pin voltage to safe levels using 40 W surge rating, preventing latch-up or oxide damage. |
| Signal Level Shifting | Temperature-Stable Bias Network |
|
Use Scenario: Translating 3.3 V logic signals down to 2.4 V compatible levels for analog sensor interfaces. IC Role / Device Role / Timing Role: Provides fixed 2.4 V reference point for resistor-divider attenuation or active level-shifter biasing. Use Value: Delivers consistent offset with -3.5 to 0.0 mV/K tempco, maintaining accuracy across -40 °C to +85 °C operating range. |
Use Scenario: Generating stable bias currents for op-amp input stages or transistor amplifiers requiring low-drift references. IC Role / Device Role / Timing Role: Supplies temperature-compensated reference voltage to establish quiescent operating points. Use Value: Achieves <100 μA leakage at 1 V reverse bias, minimizing error contribution in high-impedance bias networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5222BS | 2.4 V ±5 % tolerance, 225 mW Ptot, SOT-23 package | Higher tolerance and lower power rating reduce precision in reference designs but suit cost-sensitive clamping | Select when board space allows SOT-23 and ±5 % accuracy suffices for non-critical biasing |
| Vishay BZX384-C2V4 | 2.4 V ±5 % tolerance, same SOD323 package, higher 2.2–2.6 V min/max range | Looser tolerance increases design margin requirements but improves yield in high-volume manufacturing | Choose for production scalability where tighter 2.35–2.45 V control is unnecessary |
Compared with BZX384-B2V4,115, MMBZ5222BS offers lower cost but sacrifices 3× tighter tolerance and 25 % lower power handling, while BZX384-C2V4 retains identical form factor but trades ±2 % accuracy for broader voltage spread and improved process yield.

FAQ
What is the maximum continuous reverse current this diode can handle?
The BZX384-B2V4,115 has no specified maximum continuous reverse current; instead, it is rated for 5 mA test current and 300 mW total power dissipation. At 2.4 V, this corresponds to ~125 mA absolute maximum steady-state reverse current before exceeding Ptot, assuming Tamb ≤ 25 °C and proper PCB thermal design.
Can this Zener be used in series to achieve higher reference voltages?
Yes, multiple BZX384-B2V4,115 diodes may be stacked in series to generate higher reference voltages, but cumulative tolerance (±2 % per device) and thermal coupling effects must be accounted for. Differential resistance adds linearly, increasing overall impedance and reducing regulation accuracy under load variation.
How does the temperature coefficient affect regulation stability?
With a temperature coefficient ranging from -3.5 to 0.0 mV/K, the BZX384-B2V4,115 exhibits slight negative or near-zero drift over temperature. At 2.4 V, this translates to ≤0.84 mV/°C maximum change, enabling stable reference operation across -65 °C to +150 °C without external compensation.
Is this part suitable for automotive applications?
No - the BZX384-B2V4,115 is not automotive-qualified. Nexperia explicitly states in the datasheet that BZX384 series devices are non-automotive; automotive alternatives require the "-Q" suffix (e.g., BZX384-Q series) and undergo additional AEC-Q200 stress testing and qualification.
