Product details
Overview
BZX84J-C3V0,115 from Nexperia is a ±5 % tolerance Zener diode in SOD323F (SC-90) package, rated for 3.0 V nominal regulation voltage at 5 mA test current, with 500 Ω typical differential resistance and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZX84J-C3V0,115 datasheet, BZX84J-C3V0,115 pinout, BZX84J-C3V0,115 application, or BZX84J-C3V0,115 equivalent, key selection criteria include Zener voltage tolerance, surge power handling (≤40 W), thermal resistance (230 K/W), low leakage (<10 µA at 2.8 V), and surface-mount compatibility in space-constrained designs.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across load variations, with temperature coefficient of −3.5 mV/K at 5 mA, enabling predictable drift compensation in bias networks. Its low 500 Ω differential resistance ensures minimal voltage shift under 1 mA to 10 mA operating current changes.
Designed for transient-tolerant regulation, it sustains non-repetitive peak reverse power up to 40 W (tp = 100 µs, square wave) and total DC power dissipation ≤550 mW at Tamb ≤25 °C on FR4 PCB with 1 cm² cathode pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.0 V nominal at IZ = 5 mA; actual range 2.8 V to 3.2 V (±5 %) |
| Differential Resistance (rdiff) | 500 Ω typical at IZ = 5 mA; defines voltage regulation stiffness under load change |
| Reverse Current (IR) | <10 µA at VR = 2.8 V; ensures low standby power loss in voltage reference paths |
| Forward Voltage (VF) | 1.1 V max at IF = 100 mA; supports bidirectional clamping or dual-use protection circuits |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs; enables robust ESD/surge suppression in automotive signal lines |
| Junction Temperature (Tj) | 150 °C max; allows operation in under-hood environments with localized heating |
| AEC-Q101 Qualified | Validated for automotive-grade reliability per stress test qualification for discrete semiconductors |
Pinout & Package
SOD323F (SC-90) plastic surface-mounted package: 2-terminal, ultra-small outline (2.7 mm × 1.35 mm × 0.95 mm), flat lead, cathode marked by bar.
| 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; completes reverse-bias path during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics including engine control units and body modules |
| Low differential resistance | 500 Ω typical ensures <±15 mV output shift over 1–10 mA current variation |
| Small SOD323F footprint | Enables placement in high-density PCB layouts where board space is constrained to <3 mm² |
| Wide voltage tolerance series | ±5 % option balances cost and precision for non-critical biasing and clamping functions |
| Pulsed surge capability | Withstands 40 W transient power (100 µs) without degradation-critical for CAN/LIN bus protection |
Applications
| Automotive Sensor Biasing | USB Port Overvoltage Clamp |
|---|---|
Use Scenario: Providing stable 3.0 V reference for analog sensor front-ends in engine coolant temperature or pressure modules. IC Role / Device Role / Timing Role: Zener diode acts as shunt voltage reference, absorbing excess current to hold bias node steady despite supply ripple. Use Value: ±5 % tolerance and −3.5 mV/K TC enable predictable offset calibration across −40 °C to +125 °C ambient. |
Use Scenario: Clamping D+ and D− lines to 3.0 V against ESD events in USB 2.0 host ports. IC Role / Device Role / Timing Role: Reverse-biased Zener conducts surge current away from PHY IC inputs during IEC 61000-4-2 contact discharge. Use Value: 40 W non-repetitive peak power rating absorbs 8 kV HBM-level transients without failure. |
| Industrial PLC Input Protection | Low-Power MCU Reset Circuit |
Use Scenario: Protecting 24 V digital input channels from field-wiring transients in programmable logic controllers. IC Role / Device Role / Timing Role: Shunt regulator limits voltage seen by optocoupler input stage during line surges. Use Value: 550 mW total power dissipation supports continuous operation under sustained 26 V overvoltage conditions. |
Use Scenario: Generating clean 3.0 V reset threshold for ARM Cortex-M0+ microcontrollers in battery-powered IoT nodes. IC Role / Device Role / Timing Role: Zener sets precise trip point for external reset supervisor IC or comparator input. Use Value: Low 10 µA leakage at 2.8 V minimizes quiescent current drain in sleep mode. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V0,115 | Same SOD323F package and 3.0 V rating, but ±5 % tolerance without AEC-Q101 qualification | Lacks automotive stress-test validation; suitable only for commercial-grade consumer or industrial equipment | Select when automotive qualification is unnecessary and cost sensitivity outweighs reliability requirements |
| MMSZ4683T1G | 3.0 V ±5 %, SOD-123 package (larger footprint), 500 mW Ptot, no AEC-Q101 listing | Higher thermal resistance (300 K/W) reduces surge margin; incompatible with ultra-dense layouts | Choose only if legacy SOD-123 footprint must be retained and automotive compliance is not required |
Compared with BZX84J-C3V0,115, the BZX84-C3V0,115 omits automotive qualification while retaining identical electrical specs, whereas MMSZ4683T1G trades package miniaturization and AEC-Q101 for broader distributor availability and legacy design reuse.

FAQ
What is the maximum continuous Zener current for BZX84J-C3V0,115 at 25 °C ambient?
The device supports up to 250 mA forward current (IF), but its Zener operating current is limited by power dissipation: at 3.0 V and 550 mW Ptot, maximum continuous IZ is 183 mA. However, thermal derating applies above 25 °C ambient-junction temperature must remain ≤150 °C.
How does the −3.5 mV/K temperature coefficient affect regulation accuracy over temperature?
At IZ = 5 mA, the Zener voltage shifts −3.5 mV per °C rise in junction temperature. From 25 °C to 125 °C (ΔT = 100 K), VZ decreases by 350 mV-so 3.0 V nominal becomes ~2.65 V. This drift is predictable and usable in compensated bias networks but unsuitable for precision references without correction.
Can BZX84J-C3V0,115 be used in bidirectional TVS configurations?
No-it is a unidirectional Zener diode optimized for reverse-bias regulation. While it conducts forward current (VF ≤ 1.1 V at 100 mA), it lacks symmetric breakdown characteristics or specified forward surge rating. For bidirectional protection, use purpose-built TVS diodes like PESD3V3L1BA.
Is the SOD323F package compatible with standard reflow soldering profiles?
Yes-Nexperia specifies reflow soldering as the only recommended method. The SC-90 outline supports JEDEC J-STD-020-compliant profiles, with peak temperatures up to 260 °C. Footprint dimensions (0.5 mm pad width, 0.6 mm spacing) match IPC-7351B density level A recommendations for automated assembly.
