Product details
Overview
BZX84J-B9V1,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323F (SC-90) package, rated for 9.1 V nominal Zener voltage at 5 mA, 550 mW total power dissipation, and AEC-Q101 qualified for automotive use. It provides stable reference voltage in low-power biasing, overvoltage clamping, and supply rail regulation circuits.
For engineers reviewing the BZX84J-B9V1,115 datasheet, BZX84J-B9V1,115 pinout, BZX84J-B9V1,115 application, or BZX84J-B9V1,115 equivalent, key selection criteria include Zener voltage tolerance (±2 %), differential resistance (100 Ω max at IZ = 5 mA), non-repetitive peak reverse power (40 W), thermal resistance (230 K/W), and automotive qualification status.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 9.1 V reference across load variations and temperature shifts. Its low differential resistance (≤100 Ω) ensures minimal voltage deviation under current changes from 1 mA to 20 mA.
Designed for surface-mount applications, it features AEC-Q101 qualification, junction temperature rating up to 150 °C, and thermal resistance from junction to ambient of 230 K/W on FR4 PCB with standard pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.1 V nominal at IZ = 5 mA; tight ±2 % tolerance enables precise voltage reference in feedback loops. |
| Differential Resistance (rdiff) | ≤100 Ω at IZ = 5 mA; ensures <100 mV output shift per 10 mA load change. |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C; defines maximum continuous DC power handling on standard FR4 board. |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for tp = 100 μs square wave; supports transient overvoltage suppression in automotive ESD events. |
| Reverse Current (IR) | ≤0.5 μA at VR = 7.2 V; guarantees low leakage in high-impedance bias networks. |
| Temperature Coefficient (SZ) | +3.8 to +7.0 mV/K at IZ = 5 mA; enables predictable drift compensation in temperature-stable references. |
| Junction Temperature (Tj) | 150 °C maximum; allows operation in under-hood automotive environments without derating below 125 °C ambient. |
Pinout & Package
SOD323F (SC-90) plastic surface-mount package: 1.35 mm × 0.80 mm body, 0.65 mm lead pitch, 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 for correct PCB orientation. |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-biased configuration establishes Zener conduction path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock per discrete semiconductor stress standards. |
| Low differential resistance | ≤100 Ω at 5 mA enables <±50 mV regulation error across 1–10 mA operating range in precision references. |
| Small SOD323F footprint | 1.35 mm × 0.80 mm body size supports high-density PCB layouts in space-constrained modules like ADAS sensors and body control units. |
| Wide Zener voltage range | Part of 74-type series spanning 2.4 V to 75 V; BZX84J-B9V1,115 fills 9.1 V node requirement with ±2 % tolerance for mid-range rail stabilization. |
| Pulsed surge capability | 40 W non-repetitive peak power at 100 μs pulse width meets ISO 7637-2 pulse 1/2a/3a immunity requirements for 12 V vehicle systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C9V1,115 | ±5 % tolerance (vs. ±2 %); same SOD323F package, 9.1 V nominal, 40 W PZSM. | Acceptable where cost sensitivity outweighs precision; higher VZ spread increases ADC gain error risk. | Select when budget constraints dominate and system calibration compensates for wider tolerance. |
| MMSZ4687T1G | ±5 % tolerance; SOD-123 package (larger footprint); 9.1 V nominal; 500 mW Ptot; no AEC-Q101 claim. | Not suitable for automotive; usable in industrial/commercial designs where board space allows larger package. | Choose only for non-automotive applications requiring legacy footprint compatibility or alternate sourcing. |
Compared with BZX84J-B9V1,115, the BZX84-C9V1,115 trades precision for cost, while MMSZ4687T1G sacrifices automotive qualification and board density-making the original optimal for AEC-Q101-compliant, space-constrained 9.1 V reference designs.

FAQ
What is the maximum continuous forward current for BZX84J-B9V1,115?
The absolute maximum forward current is 250 mA per limiting values table. However, typical operation uses reverse bias; forward conduction is limited to brief pulses during power-up sequencing or fault conditions, with VF ≤ 1.1 V at 100 mA per electrical characteristics.
How does the ±2 % Zener voltage tolerance impact circuit accuracy?
At 9.1 V nominal, ±2 % corresponds to ±0.182 V deviation (8.918 V to 9.282 V). In feedback networks, this directly sets worst-case output voltage error; for example, a 5 V LDO using this Zener in divider-based sensing would exhibit ~±1.8 % output variation without trimming.
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: Ptot(Tamb) = 550 mW × (1 − (Tamb − 25)/125). At 85 °C ambient, maximum allowed Ptot drops to 308 mW to maintain Tj ≤ 150 °C.
Can BZX84J-B9V1,115 replace older BZX84 variants in existing designs?
Yes, with verification. It shares identical SOD323F package, pinout, and electrical specs with legacy BZX84-B9V1 but adds AEC-Q101 qualification and updated surge ratings. Confirm layout clearance and thermal pad design match SC-90 reflow footprint in Figure 12 before drop-in replacement.
