Product details
Overview
3.0SMCJ10CAQ-13 from Diodes Incorporated is a bi-directional 3000W surface-mount transient voltage suppressor (TVS) designed for automotive power-line surge protection. It features a 10V reverse standoff voltage (VRWM), 17.0V max clamping voltage (VC) at 176.5A peak pulse current, and AEC-Q101 qualification for under-hood applications such as engine control units and body electronics.
For engineers reviewing the 3.0SMCJ10CAQ-13 datasheet, 3.0SMCJ10CAQ-13 pinout, 3.0SMCJ10CAQ-13 application, or 3.0SMCJ10CAQ-13 equivalent, this device is selected for ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD compliance in 12V/24V automotive systems requiring robust bidirectional clamping with <100ns response time and IATF16949 traceability.
Technical Context
This TVS diode operates as a bi-directional clamping device across both polarities, enabling protection of differential or floating signal/power lines without polarity dependency. Its 3000W peak pulse power rating is validated per 10×1000μs waveform, with thermal derating to 50% at +125°C ambient.
The device exhibits low dynamic impedance (<0.1Ω typical) during clamping, ensuring minimal voltage overshoot during fast transients. Its 1.0mA breakdown test current and ≤2.0μA reverse leakage at VRWM support stable DC blocking while maintaining rapid avalanche turn-on under surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains 10×1000μs surges up to 176.5A without failure |
| Reverse Standoff Voltage | 10.0V - blocks normal 12V automotive supply with 20% margin before clamping |
| Max Clamping Voltage | 17.0V @ 176.5A - limits downstream IC voltage to safe level during ISO7637-2 Pulse 1 (-150V) |
| Breakdown Voltage | 11.1–12.27V @ 1.0mA - ensures predictable, repeatable avalanche initiation |
| Operating Temperature | -55°C to +175°C - supports placement near engines or in battery junction boxes |
| ESD Rating | ±30kV air/contact discharge per ISO10605 - eliminates need for secondary ESD protection |
| AEC-Q101 Qualified | Yes - certified for automotive use with PPAP documentation and IATF16949 manufacturing |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic with UL 94V-0 flammability rating and matte tin lead finish. Moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode Band (Marked End) | Anode for bi-directional operation | Identifies terminal polarity; functions as anode during positive transients and cathode during negative transients |
| Opposite Terminal | Cathode for bi-directional operation | Completes symmetrical clamping path; no fixed polarity-enables bidirectional surge shunting |
Key Features
| Feature | Design Value |
|---|---|
| 3000W Peak Pulse Power | Handles ISO7637-2 Pulse 1 (-150V) and Pulse 3a (-220V) without degradation in automotive 12V systems |
| Bi-directional Clamping | Protects AC-coupled or floating buses (e.g., LIN, CAN FD stubs) without external polarity management |
| Low Clamping Ratio (VC/VRWM = 1.7) | Minimizes overvoltage stress on protected ICs compared to unidirectional alternatives with higher ratios |
| AEC-Q101 + IATF16949 | Enables direct integration into Tier 1 BOMs with full change control, PPAP submission, and lot traceability |
| Halogen/Antimony-Free | Meets automotive "Green" requirements (<900ppm Br, <900ppm Cl, <1000ppm Sb) for end-of-life recycling |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) LIN Bus |
|---|---|
Use Scenario: 12V battery feed to microcontroller power rails exposed to load dump and alternator ripple. IC Role / Device Role: Primary surge clamp on main VDD input, placed upstream of LDOs and DC-DC converters. Use Value: Limits transient voltage to ≤17.0V during ISO7637-2 Pulse 1 (-150V), preventing latch-up or gate oxide damage in 3.3V/5V logic. |
Use Scenario: LIN physical layer transceiver interface subjected to ESD events and cable coupling noise. IC Role / Device Role: Bi-directional line protector between LIN transceiver and harness connector. Use Value: Clamps ±30kV ESD strikes per ISO10605 without affecting LIN signal integrity due to low capacitance (<100pF typical). |
| Automotive Infotainment Display Power | ADAS Camera Module Power Input |
Use Scenario: 5V/12V supply to TFT display controller in center console, subject to ignition switching noise. IC Role / Device Role: Secondary clamping stage after primary fuse and common-mode choke. Use Value: Suppresses repetitive 100V–200V spikes from relay coil back-EMF, extending display IC lifetime by >5× vs. unprotected design. |
Use Scenario: 12V input to image sensor and serializer ICs in rear-view camera housing mounted near bumper. IC Role / Device Role: First-line defense against road-induced surges and electrostatic discharge during service. Use Value: Withstands 176.5A peak current per pulse while maintaining TJ ≤150°C, avoiding thermal runaway during repeated exposure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | 2000W PPK, same VRWM/VC but lower IPP (104A vs. 176.5A); SMC package has 2× thermal mass vs. SMB | Limited to lower-energy transients (ISO7637-2 Pulse 2a only); unsuitable for Pulse 1 or 3a in 12V systems | Select when cost sensitivity outweighs surge margin and board space allows larger SMC footprint |
| 1.5SMC10CA | 1500W PPK, identical VRWM/VC but 75A IPP; same SMC package but lower surge rating | Valid for ISO10605 only; fails under ISO7637-2 Pulse 1 due to insufficient energy handling | Use only in non-safety-critical interior modules where full automotive surge immunity is not required |
Compared with SMBJ10CA and 1.5SMC10CA, the 3.0SMCJ10CAQ-13 delivers 50% higher peak power and 70% greater peak current-enabling single-device compliance with full ISO7637-2 Pulse 1/2a/3a/3b in compact SMC form factor, reducing BOM count and PCB area versus stacked TVS solutions.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ10CAQ-13 at its rated peak pulse current?
The maximum clamping voltage (VC) is 17.0V at 176.5A peak pulse current, measured per 10×1000μs waveform per Figure 4 of DS40742 Rev. 12-2. This value is guaranteed across -55°C to +175°C operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 3.0SMCJ10CAQ-13 unidirectional or bi-directional, and how is polarity identified?
The "C" suffix confirms it is bi-directional, with symmetrical clamping behavior for both positive and negative transients. Polarity is marked by a cathode band at one end; however, both terminals function interchangeably as anode/cathode depending on transient polarity-no fixed orientation is required during placement.
Does the 3.0SMCJ10CAQ-13 meet AEC-Q101 requirements for automotive use?
Yes-it is fully AEC-Q101 qualified, PPAP capable, and manufactured in IATF16949-certified facilities. Test reports include high-temperature operating life (HTOL), temperature cycling, and ESD qualification per ISO10605, with full documentation available upon request for Tier 1 validation.
How does the SMC package of the 3.0SMCJ10CAQ-13 compare thermally to SMB or SOD-123 packages?
The SMC package provides 2.5× the thermal mass of SMB and 6× that of SOD-123, enabling higher surge energy absorption without thermal runaway. Its 8.00mm² copper pad recommendation supports 300A peak forward surge current, whereas SMB is limited to ~150A and SOD-123 to ~40A under identical conditions.
