Product details
Overview
BZX84J-C3V3,115 from Nexperia is a 3.3 V ±5 % Zener voltage regulator diode in SOD323F (SC-90) package, rated for 550 mW total power dissipation and 12 A non-repetitive peak reverse current, used for precision voltage reference and overvoltage clamping in low-power analog and automotive subsystems.
For engineers reviewing the BZX84J-C3V3,115 datasheet, BZX84J-C3V3,115 pinout, BZX84J-C3V3,115 application, or BZX84J-C3V3,115 equivalent, this device delivers stable 3.3 V regulation at 5 mA test current with 500 Ω differential resistance, AEC-Q101 qualification, and surface-mount compatibility for space-constrained PCB designs.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 3.3 V reference across load and supply variations, with a temperature coefficient of −3.5 to 0 mV/K and typical reverse current ≤5 µA at VR = 1 V. Its low 500 Ω differential resistance ensures minimal voltage shift under dynamic current loads.
Designed for automotive-grade reliability, it sustains 12 A pulsed reverse current (tp = 100 µs, square wave) and meets AEC-Q101 stress testing requirements. Thermal resistance from junction to ambient is 230 K/W on FR4 PCB, limiting steady-state power handling without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.3 V nominal, ±5 % tolerance at IZ = 5 mA - defines precise clamping threshold for 3.3 V rail protection |
| Differential Resistance (rdiff) | 500 Ω max at IZ = 5 mA - limits output voltage variation under ±1 mA load change to ±0.5 V |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C - sets maximum continuous DC power before thermal derating begins |
| Non-repetitive Peak Reverse Current (IZSM) | 12 A at tp = 100 µs - supports transient surge suppression in ESD-critical interfaces |
| Forward Voltage (VF) | 1.1 V max at IF = 100 mA - enables use as low-drop rectifier or polarity indicator in dual-function circuits |
| Reverse Current (IR) | 5 µA max at VR = 1 V - ensures minimal leakage in high-impedance bias networks |
| Junction Temperature (Tj) | 150 °C max - allows operation in under-hood automotive environments with local heating |
Pinout & Package
SOD323F (SC-90) plastic surface-mounted package: 2-terminal, ultra-compact footprint (2.7 × 1.35 mm), flat lead, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; marking bar identifies this terminal - reverse-biased during Zener operation |
| 2 (A) | Anode | Connected to ground or lower-potential rail; completes current path during breakdown conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics per stress-test standard - enables use in engine control, body electronics, and ADAS sensors |
| ±5 % Zener voltage tolerance | Tighter than standard ±10 % Zeners - reduces calibration overhead in precision reference circuits |
| Low differential resistance (500 Ω) | Minimizes regulation error under varying load - critical for stable feedback in LDO pre-regulators |
| 12 A non-repetitive peak current | Handles IEC 61000-4-2 Level 4 ESD transients without degradation - suitable for USB, CAN, and sensor interface protection |
| SOD323F package | 0.65 mm profile and 2.7 mm length - fits 0402-class board space while enabling hand-soldering and automated reflow |
Applications
| Automotive Body Control Module | Industrial Sensor Signal Conditioning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V3,115 | Same Zener voltage and package, but ±5 % tolerance only; not AEC-Q101 qualified | Lacks automotive qualification - unsuitable for under-hood or safety-related modules | Select when cost sensitivity outweighs automotive compliance requirements |
| MMSZ4675-7-F | 3.3 V ±5 %, SOD-123 package (3.7 × 1.6 mm), 500 mW Ptot, 10 A IZSM | Larger footprint and lower surge rating - less optimal for dense automotive PCBs | Choose if existing layout uses SOD-123 land pattern and AEC-Q101 is not required |
Compared with BZX84J-C3V3,115, the BZX84-C3V3,115 sacrifices automotive qualification for lower unit cost, while MMSZ4675-7-F trades package size and surge capability for broader distributor availability - making the J-series optimal where AEC-Q101, small form factor, and 12 A surge handling are jointly required.

FAQ
What is the maximum continuous reverse current for BZX84J-C3V3,115 at 25 °C?
The device has no specified maximum continuous reverse current - its steady-state operation is governed by total power dissipation (550 mW). At 3.3 V Zener voltage, this corresponds to ~167 mA average reverse current before exceeding Ptot at Tamb = 25 °C. Derating applies above 25 °C per Rth(j-a) = 230 K/W.
Can BZX84J-C3V3,115 be used in series for higher voltage regulation?
No - Zener diodes in series exhibit cumulative tolerance and temperature coefficient errors, and mismatched dynamic impedance causes uneven voltage division. For >3.3 V references, use a single higher-voltage Zener (e.g., BZX84J-C5V1) or an integrated voltage reference IC instead.
Is the SOD323F package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method. The SOD323F footprint matches JEDEC MS-012 standards, and the device withstands peak temperatures up to 260 °C for 10 seconds, fully compliant with IPC/JEDEC J-STD-020 moisture sensitivity level 1.
How does the −3.5 to 0 mV/K temperature coefficient affect regulation accuracy?
Over −40 to +125 °C, this TC introduces ≤0.55 V drift (0.55 % of 3.3 V) in worst-case polarity - acceptable for non-precision references. For tighter stability, pair with a thermistor-compensated network or select a 5.1 V+ Zener with positive TC to offset circuit-level drift.
