Product details
Overview
BZX84J-C9V1,115 from Nexperia is a Zener voltage regulator diode in SOD323F (SC-90) package, designed for precision voltage reference and overvoltage protection in low-power circuits. It delivers 9.1 V nominal regulation at 5 mA test current, ±5 % tolerance, 100 Ω typical differential resistance, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZX84J-C9V1,115 datasheet, BZX84J-C9V1,115 pinout, BZX84J-C9V1,115 application, or BZX84J-C9V1,115 equivalent, key selection criteria include Zener voltage accuracy, surge power handling (40 W non-repetitive), thermal resistance (230 K/W junction-to-ambient), low leakage (<0.5 µA at 7.3 V), and surface-mount compatibility with FR4 PCBs.
Technical Context
This device operates as a two-terminal shunt regulator, maintaining stable output voltage by conducting reverse current above its breakdown threshold. Its 9.1 V nominal Zener voltage is specified at IZ = 5 mA with temperature coefficient of +3.8 mV/K to +7.0 mV/K across operating current range.
The diode exhibits low dynamic impedance (100 Ω typ. at 5 mA), enabling tight regulation under varying load conditions. It supports pulsed reverse power dissipation up to 40 W (tp = 100 µs, square wave, Tj = 25 °C), and is rated for continuous operation at Ptot ≤ 550 mW on standard FR4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.1 V nominal at IZ = 5 mA; ±5 % tolerance ensures predictable clamping in 9 V rail protection. |
| Differential Resistance (rdiff) | 100 Ω typical at IZ = 5 mA; minimizes output voltage shift under load current variation. |
| Reverse Leakage (IR) | < 0.5 µA at VR = 7.3 V; enables low-quiescent-current biasing in sensor interfaces. |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs; provides transient overvoltage suppression for ESD and surge events. |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C on FR4 PCB; defines maximum steady-state power handling in compact layouts. |
| Junction Temperature Range | –55 °C to +150 °C; supports operation in under-hood automotive and industrial environments. |
| AEC-Q101 Qualified | Validated for automotive electronics per stress-test qualification standard; suitable for safety-critical subsystems. |
Pinout & Package
Package: SOD323F (SC-90), ultra-small flat-lead surface-mount plastic package (2.7 × 1.6 × 0.95 mm), optimized for high-density PCB assembly and automated reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Marked side) | Cathode (K) | Connected to regulated output node; marking bar identifies cathode for correct orientation during placement. |
| 2 | Anode (A) | Connected to ground or lower-potential reference; completes shunt path when reverse-biased above VZ. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |
| Low differential resistance | 100 Ω typical at 5 mA enables <10 mV output deviation per 1 mA load change in feedback networks. |
| Wide Zener voltage range | 9.1 V nominal fits 9 V supply rail stabilization, logic-level clamping, and ADC reference buffering. |
| Small SOD323F footprint | 2.7 × 1.6 mm outline allows placement in space-constrained modules like ECUs and sensor transmitters. |
| Controlled temperature coefficient | +3.8 to +7.0 mV/K supports predictable drift compensation in temperature-sensitive analog circuits. |

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 | Same Zener voltage and tolerance, but not AEC-Q101 qualified; 550 mW Ptot, higher rdiff (120 Ω typ.) | Limited to commercial-grade consumer electronics; unsuitable for automotive or industrial temperature cycling. | Select only if AEC-Q101 compliance and tighter rdiff are unnecessary and cost is primary driver. |
| MMSZ5240B-TP | 9.1 V ±5 %, SOD-123 package (3.7 × 1.6 mm); 500 mW Ptot; rdiff = 150 Ω; no AEC-Q101 rating | Larger footprint increases board area; lower surge rating (30 W) reduces transient resilience. | Choose only if legacy SOD-123 layout reuse is required and automotive qualification is not mandated. |
Compared with BZX84-C9V1,115 and MMSZ5240B-TP, the BZX84J-C9V1,115 offers superior automotive qualification, lower dynamic impedance, and smaller SOD323F footprint-making it optimal for next-generation compact, high-reliability embedded systems where space, surge immunity, and temperature robustness are critical.

FAQ
What is the maximum continuous power dissipation for BZX84J-C9V1,115 on a standard FR4 PCB?
The total power dissipation (Ptot) is rated at 550 mW when mounted on an FR4 PCB with single-sided copper, tin-plated, and a 1 cm² cathode pad. This value assumes ambient temperature ≤25 °C; derating is required above that temperature per the 230 K/W junction-to-ambient thermal resistance.
How does the temperature coefficient affect regulation accuracy over –40 °C to +125 °C?
At IZ = 5 mA, the temperature coefficient ranges from +3.8 mV/K to +7.0 mV/K. Over a 165 °C span, this introduces a worst-case drift of ~1.16 V, meaning the actual Zener voltage may vary from approximately 8.0 V to 10.3 V across full temperature range-critical for high-precision references.
Can BZX84J-C9V1,115 be used in parallel for higher current handling?
No-Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, but even within the same batch, slight VZ mismatches cause current hogging. Parallel operation is not recommended; instead, use a single device with adequate surge rating or pair with a series pass transistor for higher current regulation.
Is the SOD323F package compatible with standard reflow soldering profiles?
Yes-the SOD323F package is qualified for reflow soldering only, with peak temperatures up to 260 °C. The recommended footprint (per Figure 12) uses 0.5 mm wide × 0.6 mm long solder pads with 0.6 mm spacing; thermal relief design is essential to avoid tombstoning during reflow.
