Product details
Overview
BZX384-C5V6,115 from Nexperia is a 5.6 V ±5 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 300 mW total power dissipation and 40 W non-repetitive peak reverse power, used for precision low-power voltage reference and overvoltage protection in signal conditioning circuits.
For engineers reviewing the BZX384-C5V6,115 datasheet, BZX384-C5V6,115 pinout, BZX384-C5V6,115 application, or BZX384-C5V6,115 equivalent, key selection criteria include nominal Zener voltage (5.6 V), tolerance (±5 %), differential resistance (400 Ω max at IZ = 5 mA), reverse current (1 μA max at VR = 4.0 V), and thermal resistance (415 K/W junction-to-ambient).
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load and temperature conditions. Its 5.6 V nominal Zener voltage exhibits a positive temperature coefficient of −2.0 to +2.5 mV/K at IZ = 5 mA, enabling predictable drift behavior in bias networks.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it supports pulsed operation up to 40 W (100 μs, square wave) and continuous DC dissipation up to 300 mW at Tamb ≤ 25 °C, with maximum junction temperature of 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.2 V to 6.0 V at IZ = 5 mA - defines regulation band for stable reference generation |
| Differential Resistance (rdif) | ≤400 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Current (IR) | ≤1 μA at VR = 4.0 V - ensures low leakage in standby or high-impedance sensing nodes |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - enables low-loss forward conduction during transient clamping |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard PCB |
| Non-repetitive Peak Reverse Power | 40 W for tp = 100 μs - supports surge suppression in ESD or inductive kick scenarios |
| Junction-to-Ambient Thermal Resistance | 415 K/W - limits temperature rise under steady-state operation on standard FR4 layout |
Pinout & Package
The BZX384-C5V6,115 is housed in a SOD323 (SC-76) surface-mount plastic package measuring 1.8 mm × 1.35 mm × 0.95 mm, with 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 determines reverse-bias orientation for Zener operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for breakdown conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective voltage referencing where tight regulation is not required, e.g., supply rail monitoring |
| Low 300 mW power rating | Suitable for space-constrained, low-power applications such as sensor biasing and microcontroller reset circuits |
| 400 Ω max differential resistance | Provides adequate regulation stability for moderate load variations in feedback or reference paths |
| Cathode-bar marking | Ensures unambiguous polarity identification during automated optical inspection and manual placement |
| SOD323 footprint compatibility | Supports high-density PCB layouts and standard reflow/wave soldering processes per Nexperia's recommended land patterns |
Applications
| Power Supply Monitoring | Signal Level Clamping |
|---|---|
|
Use Scenario: Detecting undervoltage/overvoltage conditions in 5 V logic rails feeding microcontrollers or FPGAs. IC Role / Device Role / Timing Role: Zener diode acts as precision voltage threshold detector in comparator input networks. Use Value: 5.6 V nominal breakdown provides margin above 5 V nominal rail while remaining within safe operating range of 3.3 V/5 V I/O pins. |
Use Scenario: Limiting analog sensor output swing to prevent ADC saturation or op-amp rail-to-rail overload. IC Role / Device Role / Timing Role: Bidirectional clamp using series Zener-anode configuration to restrict signal excursion. Use Value: Low 400 Ω rdif ensures minimal distortion at clamping thresholds; 1 μA IR avoids loading high-impedance sources. |
| Reference Voltage Generation | ESD Protection Interface |
|
Use Scenario: Providing stable bias voltage for current sources or amplifier offset trimming in portable instrumentation. IC Role / Device Role / Timing Role: Passive voltage reference element in low-current (<1 mA) bias networks. Use Value: ±5 % tolerance and −2.0 to +2.5 mV/K temperature coefficient allow predictable drift compensation in calibrated systems. |
Use Scenario: Secondary protection stage downstream of TVS diodes on USB or UART lines exposed to electrostatic discharge. IC Role / Device Role / Timing Role: Low-capacitance (300 pF max) shunt device absorbing residual transients after primary clamping. Use Value: 40 W peak power rating handles residual energy not absorbed by upstream TVS, without thermal runaway due to 150 °C Tj limit. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5232BS-7-F (Diodes Inc.) | Same 5.6 V nominal, ±5 % tolerance, but SOT-323 package (larger footprint, higher Ptot = 350 mW) | Higher thermal mass supports slightly longer pulse durations; less suitable for ultra-dense layouts | Select when board-level thermal management allows larger footprint and higher surge margin is needed |
| BZX384-B5V6,115 (Nexperia) | Identical package and pinout, but tighter ±2 % tolerance and lower rdif (≤300 Ω) | Improved regulation accuracy and lower output impedance for precision references | Select when tighter voltage control and lower dynamic impedance justify higher unit cost |
Compared with MMBZ5232BS-7-F, BZX384-C5V6,115 offers smaller SOD323 footprint and optimized FR4 thermal performance; compared with BZX384-B5V6,115, it trades regulation accuracy for cost efficiency in non-critical biasing roles.

FAQ
What is the maximum continuous reverse current this diode can sustain?
The BZX384-C5V6,115 does not specify a maximum continuous reverse current; instead, its operation is governed by power dissipation limits. At 5.6 V Zener voltage, the maximum continuous reverse current is approximately 53.6 mA (300 mW ÷ 5.6 V), assuming ambient temperature ≤25 °C and standard FR4 mounting. Exceeding this value risks thermal runaway.
Can this diode be used in series or parallel configurations?
Series connection is permissible for higher-voltage references, provided current matching and thermal coupling are managed; parallel connection is strongly discouraged due to mismatched Zener voltages causing current hogging and potential failure. The datasheet specifies no derating or characterization for parallel use.
How does temperature affect its Zener voltage stability?
At IZ = 5 mA, the BZX384-C5V6,115 exhibits a temperature coefficient between −2.0 mV/K and +2.5 mV/K. This means its Zener voltage may drift by up to ±12.5 mV over a 50 °C temperature change, making it suitable for non-critical biasing but not for high-precision references without compensation.
Is this part qualified for automotive applications?
No. The BZX384-C5V6,115 is explicitly designated as non-automotive qualified per Nexperia's revision history (Rev. 4, January 2023). Automotive-grade alternatives-such as the BZX384-Q series-are separately qualified to AEC-Q101 and undergo additional stress testing for under-hood environments.
