Product details
Overview
BZX384-B7V5,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 7.5 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 reference or overvoltage clamp in low-power analog supply rails and signal conditioning circuits.
For engineers reviewing the BZX384-B7V5,115 datasheet, BZX384-B7V5,115 pinout, BZX384-B7V5,115 application, or BZX384-B7V5,115 equivalent, key selection criteria include its 7.5 V ±2 % regulation accuracy, 80 Ω typical differential resistance at 5 mA, 15 μA max reverse current at 5.5 V, thermal resistance of 110 K/W to solder point, and compatibility with standard reflow soldering footprints for SOD323.
Technical Context
This Zener diode operates in reverse-biased avalanche mode to maintain stable voltage across its terminals under varying load and temperature conditions. Its 7.5 V nominal Zener voltage is specified at IZ = 5 mA with a temperature coefficient of +2.5 mV/K, indicating positive drift with junction temperature rise.
The device features low dynamic impedance (80 Ω max at 5 mA), enabling effective ripple suppression in low-current reference paths. Its SOD323 package provides compact mounting while supporting thermal resistance of 110 K/W to solder point - critical for reliability in space-constrained PCB layouts with limited copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage (VZ) | 7.35 V to 7.65 V at IZ = 5 mA - defines regulation window for precision biasing |
| Differential resistance (rdif) | 80 Ω max at IZ = 5 mA - determines output impedance and load regulation error |
| Reverse current (IR) | 15 μA max at VR = 5.5 V - sets minimum leakage in standby clamping applications |
| Total power dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C on FR4 PCB - limits continuous DC power handling |
| Non-repetitive peak reverse power (PZSM) | 40 W for tp = 100 μs - supports transient surge suppression without failure |
| Junction temperature (Tj) | −65 °C to +150 °C - enables operation in industrial ambient environments |
| Forward voltage (VF) | 0.9 V max at IF = 10 mA - relevant for polarity-check or series forward-path use |

| +2.5 mV/K temperature coefficient | Provides predictable, linear VZ drift for compensated reference circuits across −40 °C to +85 °C |
| 40 W non-repetitive surge rating | Withstands ESD and line transients per IEC 61000-4-2 Level 4 without derating |
| SOD323 footprint compatibility | Matches IPC-7351B standard land pattern for automated placement and reflow yield >99.9% |
Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5236B (ON Semiconductor) | 7.5 V ±5 % tolerance, 225 mW Ptot, 30 Ω rdif | Higher leakage (50 μA @ 5.5 V), lower surge rating (25 W) | Select for cost-sensitive consumer designs where ±5 % tolerance is acceptable and thermal margin is ample |
| BZX84-C7V5 (Nexperia) | 7.5 V ±5 % tolerance, same SOD323 package, 300 mW Ptot, 100 Ω rdif | Lower regulation precision but identical footprint and thermal performance | Choose for legacy-compatible drop-in replacement where ±2 % accuracy is not required |
Compared with MMBZ5236B, BZX384-B7V5,115 offers tighter voltage tolerance and higher surge robustness but slightly higher dynamic impedance; versus BZX84-C7V5, it delivers improved regulation accuracy at identical power and package constraints.

FAQ
What is the maximum continuous Zener current for BZX384-B7V5,115 at 25 °C ambient?
The maximum continuous Zener current is derived from Ptot = 300 mW and VZ ≈ 7.5 V, yielding IZ(max) ≈ 40 mA. However, derating is required above 25 °C ambient per the 415 K/W junction-to-ambient thermal resistance; at 70 °C ambient, usable current drops to ~22 mA to maintain Tj ≤ 150 °C.
Can BZX384-B7V5,115 be used in series for higher voltage references?
Yes - two BZX384-B7V5,115 diodes in series provide ~15 V regulation, but tolerance stacks to ±4 % (±0.6 V), and differential resistance doubles to ~160 Ω. For stable high-voltage references, parallel-series configurations with matched units or dedicated multi-Zener ICs are preferred.
Is this part qualified for automotive applications?
No - BZX384-B7V5,115 is not automotive-qualified. Nexperia explicitly states in Revision 4 that BZX384 series products changed to non-automotive qualification in 2023; automotive alternatives require the -Q suffix (e.g., BZX384-B7V5,115-Q) and separate AEC-Q200 validation.
How does the +2.5 mV/K temperature coefficient affect circuit accuracy over −40 °C to +125 °C?
Over this 165 K range, VZ shifts by +413 mV (165 × 2.5 mV/K), resulting in a final value of ~7.91 V at +125 °C. For applications requiring <1 % total drift, external compensation (e.g., thermistor network or opposite-coefficient reference) is necessary.
