Product details
Overview
BZX84J-B3V0,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323F (SC-90) package, rated for 3.0 V nominal Zener voltage at 5 mA, 550 mW total power dissipation, and AEC-Q101 qualified for automotive use. It provides precise low-voltage regulation in space-constrained PCB designs such as power rail clamping and reference generation.
For engineers reviewing the BZX84J-B3V0,115 datasheet, BZX84J-B3V0,115 pinout, BZX84J-B3V0,115 application, or BZX84J-B3V0,115 equivalent, key selection criteria include Zener voltage tolerance (±2 %), differential resistance (≤500 Ω at 5 mA), non-repetitive peak reverse power (100 W @ tp ≤ 300 μs), thermal resistance (230 K/W junction-to-ambient), and AEC-Q101 qualification status.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 3.0 V across its terminals under regulated current conditions (IZ = 5 mA). Its low differential resistance (≤500 Ω) ensures minimal voltage deviation with load current changes, while the negative temperature coefficient (−3.5 to 0 mV/K) supports predictable thermal drift behavior in ambient ranges from −55 °C to +150 °C.
The device uses planar epitaxial construction in a plastic SOD323F package with cathode-marked lead configuration. It sustains non-repetitive surge pulses up to 100 W (tp ≤ 300 μs, duty ≤ 0.02) and meets automotive reliability requirements per AEC-Q101, including high-temperature operating life and humidity robustness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.94 V to 3.06 V at IZ = 5 mA - defines tight 3.0 V regulation window for precision biasing |
| Tolerance | ±2 % - enables accurate voltage reference without post-production trimming |
| Differential Resistance (rdiff) | ≤500 Ω at IZ = 5 mA - limits output voltage shift under dynamic load variations |

| Non-repetitive Peak Reverse Power (PZSM) | 100 W for tp ≤ 300 μs - supports transient overvoltage suppression in ESD-coupled circuits |
| Reverse Current (IR) | ≤10 µA at VR = 2.2 V - ensures low leakage before breakdown onset |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables operation in under-hood automotive environments |
Pinout & Package

| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, and H3TRB testing |
| Low differential resistance | ≤500 Ω ensures <±30 mV output shift across 1–10 mA Zener current range |
| Small SOD323F footprint | 2.3 mm × 1.35 mm area saves >60 % board space vs. DO-35 or SOD123 packages |
| Wide operating temperature | −55 °C to +150 °C junction range supports engine control unit (ECU) and ADAS module deployment |
| Pulsed surge capability | 100 W non-repetitive pulse handling protects downstream ICs from ESD and load dump transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V0,115 | ±5 % tolerance (vs. ±2 %); same SOD323F package and 3.0 V nominal VZ | Acceptable where tighter regulation not required; higher IR (≤100 µA at VR = 2.2 V) | Select for cost-sensitive consumer applications where ±5 % VZ variation is acceptable |
| MMSZ4675T1G | ±5 % tolerance; SOD-123 package (larger footprint); 3.0 V VZ; 500 mW Ptot | Requires PCB layout change; higher Rth(j-a) (~300 K/W) reduces thermal margin | Choose only if SOD-123 is already standardized in design and AEC-Q101 is not mandatory |
Compared with BZX84J-B3V0,115, the BZX84-C3V0,115 trades regulation precision for lower cost, while MMSZ4675T1G sacrifices automotive qualification and thermal performance for legacy package compatibility-neither offers the combined ±2 % tolerance, AEC-Q101 compliance, and SOD323F space efficiency of the original.

FAQ
What is the maximum continuous Zener current for BZX84J-B3V0,115 at 25 °C ambient?
The maximum continuous forward current is not applicable; as a Zener diode, it operates in reverse bias. At Tamb = 25 °C, the maximum DC reverse current is derived from Ptot = 550 mW and VZ ≈ 3.0 V, yielding ~183 mA. However, the absolute maximum rated reverse current is 250 mA per limiting values table, with derating above 25 °C based on Rth(j-a) = 230 K/W.
Does BZX84J-B3V0,115 support reflow soldering only, or can it be hand-soldered?
Nexperia specifies reflow soldering as the only recommended method for BZX84J-B3V0,115. Hand-soldering is not advised due to thermal stress risks: peak reflow temperature is 260 °C for ≤10 s, while manual iron contact exceeds localized thermal limits and may damage the die or bond wires. The SOD323F package geometry also makes hand-soldering prone to bridging or tombstoning.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
At IZ = 5 mA, the temperature coefficient ranges from −3.5 to 0 mV/K. Over a 165 K span, this produces a worst-case VZ drift of −578 mV to 0 mV - but actual drift is bounded by the ±2 % initial tolerance (±60 mV) and measured typical behavior. In practice, total variation remains within ±85 mV across that range, verified in Nexperia's Fig. 6 characterization data.
Is the cathode marking bar electrically connected to Pin 1 in all SOD323F variants of this series?
Yes - per Table 2 "Pinning information", Pin 1 is unambiguously defined as the cathode (K), and the marking bar on the package top surface aligns with Pin 1. This is consistent across all BZX84J-x types in SOD323F packaging, confirmed by Nexperia's package outline diagram (Fig. 11) and marking table (Table 4), where BZX84J-B3V0 maps to code "ST" with bar orientation matching Pin 1 location.
