Product details
Overview
BZX384-B5V6,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 5.6 V nominal breakdown at 5 mA, with 300 mW total power dissipation and 40 W non-repetitive peak reverse power handling. It serves as a precision reference or low-power voltage clamp in power supply feedback paths, sensor biasing circuits, and overvoltage protection stages.
For engineers reviewing the BZX384-B5V6,115 datasheet, BZX384-B5V6,115 pinout, BZX384-B5V6,115 application, or BZX384-B5V6,115 equivalent, this page delivers verified electrical parameters, thermal behavior, cathode/anode terminal mapping, real-world regulation use cases, and validated alternative parts for design flexibility and supply continuity.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable voltage across its terminals under varying load or input conditions. Its 5.6 V nominal Zener voltage is specified at IZ = 5 mA, with differential resistance ≤400 Ω and temperature coefficient of −2.0 to +2.5 mV/K, enabling predictable drift compensation in temperature-sensitive references.
The device features low junction-to-ambient thermal resistance (415 K/W on FR4 PCB), supports pulsed surge currents up to 6.0 A (100 μs), and exhibits reverse leakage <2 μA at VR = 4.0 V - critical for low-quiescent-current bias networks and high-impedance sensing nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.49 V to 5.71 V at IZ = 5 mA - defines tight regulation window for feedback loop stability |
| Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - sets maximum continuous DC bias current limit (~53 mA at 5.6 V) |
| Differential Resistance (rdif) | ≤400 Ω - determines output impedance and load regulation error under current variation |
| Reverse Leakage (IR) | ≤2 μA at VR = 4.0 V - ensures minimal parasitic current draw in high-Z reference dividers |
| Non-repetitive Peak Power (PZSM) | 40 W - enables transient overvoltage clamping without failure during ESD or surge events |
| Junction Temperature (Tj) | −65 °C to +150 °C - supports operation in industrial ambient environments with localized heating |
| Package | SOD323 (SC-76) - 1.35 mm × 0.85 mm footprint ideal for space-constrained PCB layouts |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package with two leads: compact 1.35 mm × 0.85 mm body, 0.45 mm lead pitch, and cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity marker aligns with PCB silkscreen bar |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction with cathode |
Key Features
| Feature | Design Value |

| 40 W non-repetitive peak power rating | Provides robust transient suppression capability in unprotected input rails |
| Thermal resistance Rth(j-a) = 415 K/W | Allows safe operation at full power on standard FR4 PCB without heatsinking |
| Cathode-bar marking | Ensures unambiguous orientation during automated placement and visual inspection |
Applications
| Power Supply Feedback Reference | Sensor Biasing Network |
|---|---|
Use Scenario: Stabilizing output voltage in isolated flyback or buck converter feedback loops using optocoupler-coupled TL431 alternatives. IC Role / Device Role / Timing Role: Zener reference providing fixed 5.6 V threshold to comparator or optocoupler LED anode.

IC Role / Device Role / Timing Role: Low-drift voltage source establishing known excitation potential for ratiometric measurements. Use Value: Enables sub-0.5 % measurement repeatability by minimizing reference drift-induced offset errors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5232BS-7-F | 5.6 V ±5 %, SOT-323 package, 200 mW Ptot, rdif ≤ 130 Ω | Higher differential resistance but lower thermal resistance (Rth(j-a) ≈ 300 K/W) | Preferred where board space allows larger SOT-323 and tighter thermal budget exists |
| BZX384-C5V6,115 | 5.2 V to 6.0 V (±5 %), same SOD323 package, identical Ptot and surge rating | Wider voltage spread increases output uncertainty but improves yield in cost-sensitive designs | Select when ±2 % tolerance is unnecessary and BOM simplification across multiple Zener voltages is required |
Compared with BZX384-B5V6,115, MMBZ5232BS-7-F trades tighter thermal performance for reduced regulation precision, while BZX384-C5V6,115 retains identical form factor and surge capability at lower cost and relaxed voltage accuracy - enabling trade-offs between stability, thermal margin, and procurement economics.

FAQ
What is the maximum continuous forward current for BZX384-B5V6,115?
The device is not intended for forward conduction; its absolute maximum forward current is 250 mA per limiting values table, but typical operation occurs in reverse breakdown. Forward voltage is 0.9 V at 10 mA - sufficient only for brief polarity-check or test conditions, not sustained forward bias.
Can BZX384-B5V6,115 replace a 5.1 V Zener in an existing design?
No - its nominal Zener voltage is 5.6 V with ±2 % tolerance (5.49–5.71 V), so substituting it for a 5.1 V part would raise regulated output by ~10 %, potentially exceeding downstream IC voltage ratings. Always verify target regulation point before interchange.
How does temperature affect the Zener voltage of this diode?
At IZ = 5 mA, its temperature coefficient ranges from −2.0 to +2.5 mV/K. This means VZ may decrease by up to 0.14 V or increase by up to 0.175 V over a 70 °C junction rise - critical for high-accuracy references where thermal gradients must be minimized or compensated.
Is BZX384-B5V6,115 suitable for automotive applications?
No - this variant is non-automotive qualified per Nexperia's revision history. Automotive-grade equivalents (e.g., BZX384-Q series) undergo AEC-Q101 qualification and extended temperature testing. Using BZX384-B5V6,115 in automotive systems voids warranty and risks reliability under harsh environmental stress.
