Product details
Overview
BZX84J-B5V6,115 from Nexperia is a ±2 % tolerance Zener diode in SOD323F (SC-90) package, rated for 5.6 V nominal regulation at 5 mA, with 400 Ω differential resistance, 550 mW total power dissipation, and AEC-Q101 qualification for automotive voltage reference and overvoltage protection circuits.
For engineers reviewing the BZX84J-B5V6,115 datasheet, BZX84J-B5V6,115 pinout, BZX84J-B5V6,115 application, or BZX84J-B5V6,115 equivalent, this device serves as a precision low-power shunt regulator in space-constrained automotive ECUs, sensor signal conditioning, and power rail monitoring where stable 5.6 V reference and thermal robustness to 150 °C junction temperature are required.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable 5.6 V reference across its cathode–anode terminals under regulated current conditions. Its ±2 % tolerance and low 400 Ω differential resistance ensure tight voltage control with minimal drift under load variation.
Designed for surface-mount use in high-reliability environments, it features AEC-Q101 qualification, 150 °C maximum junction temperature, and non-repetitive peak reverse power dissipation of 40 W (tp = 100 μs), supporting transient surge suppression in automotive 12 V systems.
Key Specifications

| Tolerance | ±2 % - enables tighter system-level voltage margining vs. ±5 % variants |
| Differential Resistance | 400 Ω max at IZ = 5 mA - limits output voltage shift under current load changes |
| Total Power Dissipation | 550 mW at Tamb ≤ 25 °C - sets continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Power | 40 W (tp = 100 μs) - supports ESD/ISO 7637-2 pulse immunity in automotive supply lines |
| Junction Temperature Range | −55 °C to +150 °C - ensures operation in engine bay and under-hood environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability per stress test requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6,115 | ±5 % tolerance, same SOD323F package and 5.6 V nominal rating | Lower cost for non-critical biasing where ±0.28 V regulation window is acceptable | Select when BOM cost sensitivity outweighs precision requirement |
| MMSZ5232B-7-F | ±5 % tolerance, SOD-123 package (larger footprint), 500 mW Ptot | Higher thermal mass but incompatible pin layout; requires PCB redesign | Choose only if legacy MMSZ footprint reuse is mandatory and ±0.28 V tolerance suffices |
Compared with BZX84J-B5V6,115, the ±2 % BZX84-C5V6,115 offers identical form factor but looser regulation, while MMSZ5232B-7-F trades precision for thermal robustness in a larger package-neither provides drop-in replacement without design trade-offs.

FAQ
What is the maximum continuous forward current for BZX84J-B5V6,115?
The absolute maximum forward current is 250 mA per limiting values table. However, forward conduction is not its intended operating mode; the device is designed for reverse-bias Zener regulation. Continuous forward operation above 100 mA risks thermal overstress due to VF ≈ 1.1 V at that current, generating >110 mW dissipation in the small SOD323F package.
Can BZX84J-B5V6,115 be used in parallel for higher power handling?
No-Zener diodes exhibit negative temperature coefficient below ~5 V and positive above, causing current hogging and thermal runaway when paralleled. The BZX84J-B5V6,115 has a +2.5 mV/K temperature coefficient at 5 mA, making mismatched thermal coupling highly likely. Use a single higher-power Zener or active regulation instead.
What is the typical reverse leakage current at 4.5 V?
At VR = 4.5 V and Tj = 25 °C, typical reverse leakage is <1 µA, as shown in Figure 8 of the datasheet. This low IR ensures minimal quiescent current draw in standby modes of battery-powered systems, supporting >10-year shelf life in always-on sensor nodes.
How does the 40 W non-repetitive peak power rating translate to real-world surge protection?
The 40 W rating applies to 100 μs square-wave pulses at 25 °C junction temperature, corresponding to ~6.33 A peak reverse current (IZSM = √(40 W / 5.6 V)). This supports immunity against ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 2a (load dump initiation) in 12 V automotive systems when properly decoupled.
