Product details
Overview
BZX84J-B10,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323F (SC-90) package, rated for 10 V nominal Zener voltage at 5 mA test current, 550 mW total power dissipation, and AEC-Q101 qualified for automotive use. It provides stable reference voltage in low-power supply regulation and overvoltage protection circuits.
For engineers reviewing the BZX84J-B10,115 datasheet, BZX84J-B10,115 pinout, BZX84J-B10,115 application, or BZX84J-B10,115 equivalent, this page delivers verified electrical specs, thermal behavior, cathode/anode terminal mapping, automotive qualification status, and real-world design context for precision voltage clamping and biasing.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 10 V reference across its terminals under controlled current conditions. Its differential resistance of 150 Ω at IZ = 5 mA ensures predictable voltage regulation with minimal deviation under load variation.
The device exhibits a temperature coefficient of +4.5 mV/K at IZ = 5 mA, enabling predictable drift compensation in temperature-sensitive analog circuits. Its non-repetitive peak reverse power dissipation is rated at 40 W for ≥7.5 V types, supporting transient surge suppression in automotive ECUs and industrial sensors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.80 V to 10.20 V at IZ = 5 mA - tight ±2 % tolerance enables accurate voltage reference without trimming. |
| Differential Resistance (rdiff) | 150 Ω max at IZ = 5 mA - low impedance ensures stable regulation under varying load currents. |
| Reverse Current (IR) | 0.2 µA max at VR = 7.6 V - minimal leakage preserves battery life in always-on circuits. |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C - defines maximum continuous DC power handling on standard FR4 PCB. |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W at tp = 100 µs - supports ESD and load-dump transient suppression per ISO 7637-2. |
| Junction Temperature (Tj) | 150 °C max - enables operation in under-hood automotive environments. |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling. |
Pinout & Package
SOD323F (SC-90) surface-mount plastic package: 1.35 mm × 0.80 mm footprint, 0.25 mm profile, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal; carries reverse-biased current during regulation. |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for Zener conduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces. |
| ±2 % Zener voltage tolerance | Reduces need for post-assembly calibration in precision reference designs such as ADC biasing and op-amp feedback networks. |
| Low differential resistance (150 Ω) | Minimizes output voltage shift under dynamic load changes, critical for stable LDO feedback references. |
| Small SOD323F footprint | Enables high-density PCB layouts in space-constrained modules like telematics units and smart actuators. |
| 150 °C junction rating | Supports operation in high-temperature zones near power converters or motor drivers without derating. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10,115 | ±5 % tolerance (9.4–10.6 V), higher IR (0.5 µA at 7.6 V), same SOD323F package. | Acceptable where cost sensitivity outweighs precision; not suitable for <12-bit ADC references. | Select when budget constraints dominate and system-level calibration compensates for wider VZ spread. |
| MMSZ5240B-7-F | ±5 % tolerance, 500 mW Ptot, SOD-123 package (larger footprint, higher Rth(j-a) = 300 K/W). | Lower thermal performance limits continuous power in compact layouts; lacks AEC-Q101 certification. | Choose only for non-automotive consumer designs where board space and qualification are secondary. |
Compared with BZX84J-B10,115, the BZX84-C10,115 trades precision for cost, while MMSZ5240B-7-F sacrifices automotive qualification and thermal efficiency for legacy footprint compatibility-neither matches the combined AEC-Q101 compliance, ±2 % tolerance, and 550 mW power capability of the original.

FAQ
What is the maximum continuous forward current for BZX84J-B10,115?
The absolute maximum forward current is 250 mA per limiting values table. However, forward conduction is not its intended operating mode; sustained forward bias above 100 mA risks thermal runaway due to low VF (~1.1 V) and limited thermal resistance (Rth(j-a) = 230 K/W). Designers should operate it exclusively in reverse breakdown.
How does the +4.5 mV/K temperature coefficient affect circuit accuracy?
At IZ = 5 mA, the Zener voltage increases by 4.5 mV per °C rise in junction temperature. Over a -40 °C to 125 °C range, this causes ~743 mV total drift. For high-accuracy applications, this must be compensated via circuit design (e.g., complementary diode networks) or firmware correction using an onboard temperature sensor.
Can BZX84J-B10,115 replace BZX84-C10,115 in existing designs?
Yes, with functional verification: both share identical SOD323F package, pinout, and 10 V nominal rating, but BZX84J-B10,115 offers tighter ±2 % tolerance and lower IR (0.2 µA vs. 0.5 µA). No layout change is needed, though system-level testing is required to confirm improved reference stability meets design margins.
Is thermal derating required above 25 °C ambient?
Yes. With Rth(j-a) = 230 K/W, power dissipation must be linearly reduced above 25 °C. At 85 °C ambient, maximum allowable Ptot drops to 313 mW ((150 − 85) × (1/230)). Derating curves are defined in the datasheet Figure 1 and must be applied for reliable long-term operation.
