Product details
Overview
BZX384-C2V7,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 2.7 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 power supply feedback paths, sensor biasing circuits, and overvoltage protection stages.
For engineers reviewing the BZX384-C2V7,115 datasheet, BZX384-C2V7,115 pinout, BZX384-C2V7,115 application, or BZX384-C2V7,115 equivalent, this page delivers verified Zener voltage, differential resistance, temperature coefficient, reverse current limits, and thermal resistance - all critical for stable low-voltage regulation in space-constrained PCB designs.
Technical Context
This device operates in reverse-bias breakdown mode with a nominal Zener voltage of 2.7 V (min 2.50 V, max 2.90 V at IZ = 5 mA), exhibiting a temperature coefficient of –3.5 to 0.0 mV/K and differential resistance ≤600 Ω. Its low 2.7 V rating makes it suitable for 3.3 V and 2.8 V rail clamping where minimal headroom is required.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it delivers 300 mW continuous dissipation at Tamb ≤ 25 °C and withstands 40 W non-repetitive surges (tp = 100 μs). The cathode-anode polarity is marked by a bar on the SOD323 body, aligning with standard PCB silkscreen conventions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.7 V nominal at IZ = 5 mA; min/max 2.50 V / 2.90 V defines ±5 % tolerance band for stable low-voltage reference |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C on standard FR4 PCB - sets maximum continuous DC or low-duty-cycle bias current |
| Differential Resistance (rdif) | ≤600 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity in shunt regulator configurations |
| Reverse Current (IR) | ≤100 μA at VR = 1 V - ensures low leakage in standby or high-impedance sensing nodes |
| Non-repetitive Peak Reverse Power | 40 W for tp = 100 μs - enables transient overvoltage suppression without device failure |
| Junction-to-Ambient Thermal Resistance | 415 K/W in free air - confirms need for thermal relief or adjacent copper pour if operating near Ptot limit |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - supports use as forward-biased clamp or LED driver series element when needed |
Pinout & Package
The BZX384-C2V7,115 is housed in a SOD323 (SC-76) plastic surface-mount package measuring 1.8 mm × 1.35 mm × 0.95 mm, with gull-wing leads and cathode indicated by a marking bar on the component body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node in shunt configuration; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential reference; reverse-bias voltage applied between anode and cathode to enable Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective regulation where tight voltage accuracy is not required - e.g., non-critical biasing or coarse overvoltage detection |
| Low 2.7 V breakdown voltage | Supports regulation and clamping on 3.3 V and 2.8 V rails without additional level-shifting circuitry |
| SOD323 footprint compatibility | Matches industry-standard 0805-equivalent land pattern (2.2 mm × 1.35 mm), enabling drop-in replacement in high-density layouts |
| 40 W surge capability | Provides robustness against ESD and short-duration transients per IEC 61000-4-2 Level 4 without external TVS staging |
| 150 °C maximum junction temperature | Allows operation in thermally demanding environments such as enclosed industrial controllers or automotive under-hood modules (non-automotive qualified) |
Applications
| Power Supply Feedback Clamping | Sensor Bias Reference |
|---|---|
Use Scenario: Stabilizing error amplifier input in adjustable DC-DC converter feedback loop. IC Role / Device Role / Timing Role: Shunt regulator providing precise 2.7 V reference to set output voltage via resistor divider. Use Value: Maintains ±1.5 % output regulation across line/load variations due to low rdif and stable VZ tempco. |
Use Scenario: Supplying stable bias voltage to analog temperature or pressure sensor ICs. IC Role / Device Role / Timing Role: Low-noise, low-leakage voltage reference replacing higher-cost precision references. Use Value: Delivers <100 μA reverse leakage at 1 V reverse bias, minimizing sensor offset drift in battery-powered IoT nodes. |

IC Role / Device Role / Timing Role: Fast-acting Zener clamp limiting pin voltage to ≤2.9 V during transients. Use Value: Withstands 40 W non-repetitive surges (100 μs), preventing latch-up or oxide damage without adding series resistance. |
Use Scenario: Level-shifting and clamping signals between 2.8 V and 3.3 V logic families. IC Role / Device Role / Timing Role: Bidirectional clamp defining upper signal rail at 2.7 V while conducting forward at ~0.9 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5221BS-7-F (Diodes Inc.) | 2.7 V ±5 %, SOT-23 package, 225 mW Ptot, rdif ≤ 100 Ω | Lower power rating and tighter rdif; requires larger PCB area and offers better regulation but reduced surge margin | Select when tighter dynamic regulation is prioritized over transient robustness and board space is available. |
| BZX84-C2V7 (Nexperia) | Same 2.7 V ±5 % spec, but in larger SOT-23 package with 350 mW Ptot and 400 Ω rdif | Higher continuous power handling but less compact; compatible pinout with different thermal profile | Choose for legacy designs using SOT-23 footprints or where higher steady-state dissipation is expected. |
Compared with MMBZ5221BS-7-F, BZX384-C2V7,115 trades lower differential resistance for superior surge immunity and smaller footprint; versus BZX84-C2V7, it sacrifices 50 mW continuous power for 35 % board area reduction and identical Zener characteristics.

FAQ
What is the maximum reverse voltage before breakdown for BZX384-C2V7,115?
The guaranteed minimum Zener voltage is 2.50 V at IZ = 5 mA, meaning breakdown begins no earlier than this value. At 1 V reverse bias, leakage remains ≤100 μA - well below conduction threshold. Full regulation occurs only above 2.50 V, with typical knee sharpness confirmed by ≤600 Ω differential resistance.
Can BZX384-C2V7,115 be used in place of a 3.3 V Zener diode?
No - its nominal 2.7 V breakdown is specifically optimized for 2.8 V/3.3 V rail clamping, not replacement of 3.3 V Zeners. Using it as a 3.3 V reference would result in premature conduction and excessive current draw. For 3.3 V regulation, BZX384-C3V3 (3.3 V ±5 %) is the functionally matched variant.
How does thermal resistance affect performance in a densely routed PCB?
With Rth(j-a) = 415 K/W in free air, self-heating rises ~125 °C per 300 mW - exceeding the 150 °C Tj limit. On a standard FR4 board with minimal copper, continuous operation above 100 mW requires thermal relief or local copper pour. Derating to 150 mW ensures safe junction temperature at 70 °C ambient.
Is BZX384-C2V7,115 suitable for automotive applications?
No - per Nexperia's revision history (Rev. 4, Jan 2023), the BZX384 series is explicitly designated non-automotive qualified. It lacks AEC-Q200 stress testing and automotive-grade screening. For automotive use, Nexperia's -Q qualified equivalents (e.g., BZX384-Q series) must be selected instead.
