Product details
Overview
BZX84J-C2V4,115 from Nexperia is a 2.4 V ±5 % Zener voltage regulator diode in SOD323F (SC-90) package, rated for 550 mW total power dissipation and 100 mA forward current, with low differential resistance (450 Ω at IZ = 5 mA) and AEC-Q101 qualification for automotive voltage reference and overvoltage protection circuits.
For engineers reviewing the BZX84J-C2V4,115 datasheet, BZX84J-C2V4,115 pinout, BZX84J-C2V4,115 application, or BZX84J-C2V4,115 equivalent, key selection criteria include Zener tolerance (±5 %), non-repetitive surge capability (12 A peak reverse current), thermal resistance (230 K/W junction-to-ambient), and SC-90 footprint compatibility in space-constrained PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 2.4 V regulation across load and line variations, with temperature coefficient of −3.5 to 0 mV/K and low capacitance (450 pF at 1 MHz, VR = 0 V). Its 230 K/W thermal resistance requires careful PCB copper area design for sustained 550 mW operation.
The device supports pulsed reverse power dissipation up to 100 W (tp ≤ 300 μs, δ ≤ 0.02), enabling transient overvoltage clamping in automotive ECUs and industrial sensors. Cathode-marked SOD323F packaging ensures unambiguous polarity during automated placement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.2 V to 2.6 V at IZ = 5 mA - defines regulation window for low-voltage biasing and reference generation |
| Tolerance | ±5 % - enables cost-effective selection where tight voltage accuracy is not required |
| Differential Resistance (rdiff) | 450 Ω max at IZ = 5 mA - determines regulation stiffness under varying load current |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC power handling |
| Non-repetitive Peak Reverse Current (IZSM) | 12 A at tp = 100 μs - supports ESD/EMI transient suppression per IEC 61000-4-2 |
| Forward Voltage (VF) | 1.1 V max at IF = 100 mA - limits conduction loss when used in series forward-path configurations |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables operation in under-hood automotive environments |
Pinout & Package
SOD323F (SC-90) surface-mount plastic package: 2.3 mm × 1.35 mm × 0.95 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 orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-biased configuration enables Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, temperature cycling, and HAST |
| Low differential resistance | 450 Ω max ensures minimal voltage shift under ±1 mA load variation |
| Small SOD323F footprint | Enables high-density routing in compact modules like ADAS camera PCBs and battery management ICs |
| Wide surge capability | 100 W non-repetitive peak power (≤6.8 V types) supports ISO 7637-2 pulse 1/2a/5a protection |
| Stable temperature coefficient | −3.5 to 0 mV/K range minimizes drift across −40 °C to +125 °C operating range |
Applications
| Automotive Sensor Biasing | Industrial ADC Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C2V4,115 | Same Zener voltage and tolerance, but lacks AEC-Q101 qualification and has higher rdiff (500 Ω vs 450 Ω) | Not suitable for automotive or high-reliability industrial use; limited to consumer-grade power rails | Select only if AEC-Q101 compliance and tighter regulation are unnecessary |
| MMSZ4678T1G | 2.4 V ±5 %, SOD-123 package (3.7 mm × 1.6 mm), Ptot = 500 mW, rdiff = 500 Ω | Larger footprint increases board area; lower power rating reduces surge margin | Choose when legacy SOD-123 layout reuse is prioritized over miniaturization and automotive qualification |
Compared with BZX84J-C2V4,115, the BZX84-C2V4,115 sacrifices automotive qualification and regulation precision, while MMSZ4678T1G trades package size and surge robustness for broader distributor availability-making the J-series optimal for new AEC-Q101-compliant designs requiring SC-90 miniaturization.

FAQ
What is the maximum continuous power dissipation for BZX84J-C2V4,115 at 70 °C ambient?
At 70 °C ambient, derating applies: Ptot = 550 mW − [(70 − 25) × (550 mW / 230 K/W)] = 448 mW. This accounts for thermal resistance of 230 K/W on FR4 with 1 cm² cathode pad, ensuring safe operation without exceeding 150 °C junction temperature.
How does the ±5 % tolerance affect regulation accuracy in a 3.3 V LDO feedback network?
When used in an LDO feedback divider, ±5 % VZ introduces ±0.12 V uncertainty at 2.4 V, translating to ±3.6 % output voltage error at 3.3 V. For tighter regulation, pair with precision resistors or select BZX84J-B2V4 (±2 %) variant.
Can BZX84J-C2V4,115 replace BZX84-C2V4 in existing designs without layout changes?
Yes-both share identical SOD323F (SC-90) package dimensions and pinout. However, BZX84J-C2V4,115 adds AEC-Q101 qualification and improved rdiff, making it a drop-in upgrade for automotive or high-reliability applications without footprint modification.
What is the typical reverse leakage current at 1.5 V reverse bias?
At 1.5 V reverse bias and 25 °C, typical IR is <0.1 µA (per Fig. 8), well below the 1 µA maximum specified at VR = 1 V. This ultra-low leakage preserves battery life in always-on sensor nodes and enables use in high-impedance bias networks.
