Product details
Overview
BZX384-C4V7,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 4.7 V nominal breakdown at 5 mA, with 300 mW total power dissipation and 500 Ω maximum differential resistance, used for precision low-power voltage reference and overvoltage protection in portable power rails.
For engineers reviewing the BZX384-C4V7,115 datasheet, BZX384-C4V7,115 pinout, BZX384-C4V7,115 application, or BZX384-C4V7,115 equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance (415 K/W junction-to-ambient), reverse current limit (3 μA at 3.7 V), temperature coefficient (+0.2 mV/K), and non-repetitive surge capability (6.0 A peak).
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable DC voltage under varying load and input conditions. Its 4.7 V nominal Zener voltage is specified at IZ = 5 mA, with a typical temperature coefficient of +0.2 mV/K and differential resistance of ≤500 Ω, ensuring predictable regulation across ambient temperatures from –65 °C to +150 °C.
The device uses silicon planar epitaxial construction for stable long-term performance and low leakage. With a maximum reverse current of 3 μA at VR = 3.7 V and forward voltage of ≤0.9 V at IF = 10 mA, it supports bidirectional circuit functions including clamping, reference, and ESD-tolerant biasing in space-constrained SMD designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.40 V to 5.00 V at IZ = 5 mA - defines usable regulation window for 4.7 V nominal rail stabilization |
| Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Differential Resistance (rdif) | ≤500 Ω - determines output impedance and load regulation sensitivity |
| Reverse Current (IR) | ≤3 μA at VR = 3.7 V - ensures minimal quiescent leakage below knee voltage |
| Non-repetitive Peak Current (IZSM) | 6.0 A for tp = 100 μs - enables transient overvoltage suppression without failure |
| Thermal Resistance (Rth(j-a)) | 415 K/W - quantifies self-heating rise per watt on standard single-sided FR4 layout |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - supports use as low-drop rectifier or clamp in dual-polarity circuits |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5225BS-7-F (Diodes Inc.) | 4.8 V nominal, ±5 %, 200 mW Ptot, 22 Ω rdif | Lower dynamic impedance but reduced power margin; requires derating above 70 °C | Select when tighter regulation (lower rdif) is prioritized over surge robustness |
| BZX84-C4V7 (Nexperia) | Same 4.7 V/±5 % spec, but SOT23 package, 350 mW Ptot, 600 Ω rdif | Larger footprint, higher thermal resistance (500 K/W), less board density | Choose when legacy SOT23 compatibility or higher continuous power is needed |
Compared with MMBZ5225BS-7-F, BZX384-C4V7,115 offers superior surge immunity (6.0 A vs. 4.3 A) and lower thermal resistance (415 vs. 520 K/W), while BZX84-C4V7 trades board space for marginally higher power handling but poorer regulation stability.

FAQ
What is the maximum reverse voltage before breakdown for BZX384-C4V7,115?
The guaranteed minimum Zener voltage is 4.40 V at IZ = 5 mA, and the device begins measurable conduction above ~3.7 V. At VR = 3.7 V, reverse current is limited to ≤3 μA - this defines the practical upper bound of non-breakdown operation for design margining.
Can BZX384-C4V7,115 be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficients and manufacturing spread, causing current hogging and thermal runaway when paralleled. For higher power, use a single higher-rated device like BZX84-C4V7 or add external ballast resistors with careful thermal layout.
Is BZX384-C4V7,115 suitable for automotive applications?
No - this part is non-automotive qualified per Nexperia's revision history (Rev. 4, Jan 2023). It lacks AEC-Q101 qualification, extended temperature validation, and automotive-specific reliability testing. Use BZX384-Q series variants for automotive designs.
How does temperature affect the 4.7 V regulation accuracy?
At IZ = 5 mA, the temperature coefficient is +0.2 mV/K. Over a 100 °C range (–25 °C to +75 °C), this introduces ±20 mV drift - a ±0.43 % change relative to 4.7 V. This is additive to the ±5 % initial tolerance, resulting in worst-case regulation between 4.18 V and 5.22 V.
