Product details
Overview
BZX384-C7V5,115 from Nexperia is a 7.5 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 clamping in signal conditioning circuits.
For engineers reviewing the BZX384-C7V5,115 datasheet, BZX384-C7V5,115 pinout, BZX384-C7V5,115 application, or BZX384-C7V5,115 equivalent, key selection criteria include nominal Zener voltage (7.5 V), tolerance (±5 %), differential resistance (80 Ω at IZ = 5 mA), temperature coefficient (+2.5 mV/K), and SOD323 thermal resistance (110 K/W junction-to-solder-point).
Technical Context
This Zener diode operates in reverse breakdown to maintain stable DC voltage across its terminals under varying load or supply conditions. Its 7.5 V nominal Zener voltage is specified at 5 mA test current with ±5 % tolerance, and exhibits +2.5 mV/K positive temperature coefficient - enabling predictable drift compensation in bias networks.
The device delivers 15 μA reverse current at VR = 5.6 V and supports 4.0 A non-repetitive peak reverse current (tp = 100 μs), making it suitable for transient suppression in low-energy analog rails. Its 80 Ω dynamic impedance at 5 mA ensures minimal output voltage variation under small-signal load changes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.0 V to 7.9 V at IZ = 5 mA - defines usable regulation band for 7.5 V nominal reference |
| Tolerance | ±5 % - specifies maximum deviation from nominal 7.5 V under production conditions |
| Differential Resistance (rdif) | 80 Ω max at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Temperature Coefficient (SZ) | +2.5 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius rise in junction temperature |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C on FR4 PCB - sets continuous DC power limit for thermal design |
| Non-repetitive Peak Reverse Power | 40 W (tp = 100 μs) - defines surge energy handling capability for ESD/transient clamping |
| Reverse Current (IR) | 1 μA max at VR = 5.6 V - indicates leakage level below breakdown, critical for high-impedance biasing |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-terminal, cathode-marked with bar, 1.35 mm × 0.85 mm body, 0.45 mm lead pitch, 0.25 mm thickness.

| 2 (A) | Anode | Connected to ground or lower-potential rail; reverse-biased configuration enables Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SMD packaging | SOD323 footprint enables high-density layout in space-constrained analog sections |
| Controlled Zener tolerance | ±5 % tolerance (C-series) balances cost and precision for non-critical reference applications |
| Stable temperature behavior | +2.5 mV/K coefficient allows predictable bias point shift in ambient-varying environments |
| High surge robustness | 40 W non-repetitive peak power rating supports IEC 61000-4-2 Level 4 ESD protection |
| Low leakage performance | ≤1 μA IR at 5.6 V enables use in microamp-level bias networks without loading error |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5236BS-7-F | 7.5 V ±5 %, SOT-323 package, 200 mW Ptot, 30 Ω rdif at 20 mA | Lower power rating and tighter impedance but higher test current (20 mA vs 5 mA) | Select when board space permits SOT-323 and lower dynamic impedance is prioritized over thermal margin |
| BZX84-C7V5 | 7.5 V ±5 %, SOT-23 package, 300 mW Ptot, 80 Ω rdif at 5 mA, same TC | Larger footprint, higher thermal resistance (300 K/W vs 110 K/W junction-to-solder-point) | Choose when legacy SOT-23 compatibility is required and PCB copper area for heat sinking is limited |
Compared with BZX384-C7V5,115, MMBZ5236BS-7-F offers lower impedance at higher test current but reduced surge capacity, while BZX84-C7V5 matches power and impedance specs but sacrifices thermal performance due to larger package thermal resistance.

FAQ
What is the maximum continuous reverse current for BZX384-C7V5,115?
The device has no specified maximum continuous reverse current; instead, it is rated by power dissipation. At 7.5 V, the absolute maximum DC reverse current is 40 mA (300 mW ÷ 7.5 V), constrained by thermal limits on standard FR4 PCB. Exceeding this risks junction temperature exceeding 150 °C.
Can BZX384-C7V5,115 be used in series for higher voltage references?
Yes, but with caution: series connection multiplies voltage tolerance (±5 % each → ±10 % for two), increases total dynamic impedance, and requires matched temperature coefficients to avoid thermal runaway. For stable multi-Zener references, parallel thermal coupling and individual current limiting resistors are mandatory.
How does the +2.5 mV/K temperature coefficient affect circuit accuracy?
Over a 50 °C ambient change (e.g., 25 °C to 75 °C), the Zener voltage shifts +125 mV (2.5 mV/K × 50 K), introducing ~1.7 % error relative to 7.5 V. This must be budgeted in reference-sensitive designs; compensation techniques include using complementary TC components or digital calibration.
Is BZX384-C7V5,115 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, automotive-grade screening, and guaranteed operation across -40 °C to +125 °C extended temperature range. Automotive alternatives require explicit "-Q" suffix variants.
