Product details
Overview
3.0SMCJ13CAQ-13 from Diodes Incorporated is a bi-directional automotive transient voltage suppressor (TVS) diode in SMC package, rated for 3000W peak pulse power, 13V reverse standoff voltage (VRWM), and clamping voltage of 21.5V at 139.5A peak pulse current. It protects CAN, LIN, and sensor interfaces in engine control units and body electronics against ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD surges.
For engineers reviewing the 3.0SMCJ13CAQ-13 datasheet, 3.0SMCJ13CAQ-13 pinout, 3.0SMCJ13CAQ-13 application, or 3.0SMCJ13CAQ-13 equivalent, this AEC-Q101 qualified TVS provides verified clamping performance, IATF16949-manufactured traceability, and RoHS/halogen-free compliance for automotive-grade surge protection design-in.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling robust protection of AC-coupled or differential signal lines without polarity constraints. Its 13V VRWM ensures compatibility with 12V automotive systems while maintaining low leakage (<2µA) and fast response to transients.
The device uses silicon avalanche junction technology to achieve sub-nanosecond response time and stable clamping under 10×1000µs surge waveforms. Thermal derating follows a defined curve up to +175°C junction temperature, supporting under-hood deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single 10×1000µs surges per ISO7637-2 without failure |
| Reverse Standoff Voltage (VRWM) | 13.0V - maximum continuous DC or RMS voltage before significant leakage |
| Clamping Voltage (VC) | 21.5V @ 139.5A - limits downstream circuit voltage during worst-case surge |
| Breakdown Voltage (VBR) | 14.4–15.9V @ 1.0mA - defines precise avalanche initiation threshold |
| Peak Forward Surge Current (IFSM) | 300A @ 8.3ms - handles repetitive load dump events in alternator circuits |
| Operating Temperature | −55°C to +175°C - supports placement near engines, transmissions, and power modules |
| AEC-Q101 Qualified | Yes - validated for automotive reliability including HTOL, TCT, and ESD stress testing |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic housing with UL 94V-0 flammability rating; moisture sensitivity level 1 per J-STD-020; 0.21g weight; cathode band marking on top surface for unidirectional variants - not applicable here as 3.0SMCJ13CAQ-13 is bi-directional and marked "DED".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (Bi-directional) | Surge Current Path | Both terminals conduct identically during positive or negative transients; no polarity dependency in layout |
| Case / Body | Thermal & Mechanical Interface | Exposed copper pad on PCB absorbs heat; requires ≥8.00mm² 0.013mm-thick copper land for full 3000W rating |
Key Features
| Feature | Design Value |
|---|---|
| 3000W Peak Pulse Power | Enables single-device protection against severe load dump and ISO7637-2 Pulse 1 (−150V) without cascaded staging |
| AEC-Q101 Qualification | Validated for automotive use with PPAP documentation support and IATF16949 manufacturing control |
| Bi-directional Symmetry | Eliminates need for polarity-aware routing in differential buses like CAN FD or FlexRay physical layers |
| RoHS & Halogen-Free | Meets EU Directive 2015/863/EU with <900ppm Br, <900ppm Cl, <1000ppm Sb - compliant for global Tier 1 supply chains |
| Low Clamping Ratio | VC/VRWM = 1.65 - tight voltage margin preserves headroom for 12V system ICs with 24V absolute max ratings |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|
|

Use Value: Absorbs 3000W pulses without thermal runaway, enabling compact 6mm × 7mm PCB footprint versus multi-diode arrays. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA | 200W peak power, SMA package, same VRWM and VC but lower IPP (100A) | Not suitable for ISO7637-2 Pulse 1 (−150V); limited to infotainment USB ports or low-energy sensors | Select only when surge energy is <10% of 3.0SMCJ13CAQ-13's capability and space-constrained. |
| 1.5SMC13CA | 1500W peak power, same SMC package, identical VRWM/VC but half the PPK rating | Passes ISO7637-2 Pulse 2a (+112V) and Pulse 3b (+150V), but fails Pulse 1 (−150V) marginally | Acceptable for non-critical 12V subsystems where full 3000W headroom is not required. |
Compared with SMAJ13CA and 1.5SMC13CA, the 3.0SMCJ13CAQ-13 delivers double the surge energy handling of the latter and 15× more than the former-enabling single-point protection for high-risk power domains without parallel devices or thermal derating compromises.

FAQ
What is the clamping voltage of 3.0SMCJ13CAQ-13 at its rated peak pulse current?
The clamping voltage (VC) is 21.5V measured at 139.5A peak pulse current under the standardized 10×1000µs waveform. This value is guaranteed across the full operating temperature range (−55°C to +175°C) and defines the maximum voltage imposed on protected circuitry during surge events.
Is 3.0SMCJ13CAQ-13 unidirectional or bi-directional, and how is polarity identified?
3.0SMCJ13CAQ-13 is bi-directional, indicated by the "C" suffix in the part number and absence of cathode band marking. Its electrical behavior is symmetrical: it clamps equally for positive and negative transients, making it ideal for AC-coupled or differential signal lines without orientation constraints.
Does this TVS diode require a heatsink for 3000W operation?
No external heatsink is required. Full 3000W rating is achieved with a minimum 8.00mm² copper land area (0.013mm thick) on the PCB, which serves as the thermal interface. Derating begins above +25°C ambient per Figure 1, reaching ~70% power at +100°C board temperature.
How does AEC-Q101 qualification impact design validation for this part?
AEC-Q101 qualification confirms completion of stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and human-body-model ESD (≥8kV). This eliminates need for duplicate qualification testing by Tier 1 suppliers and enables direct PPAP submission using Diodes' certified test reports.
