Product details
Overview
SMCJ6.0CAQ-13-F from Diodes Incorporated is a bidirectional 1,500W automotive transient voltage suppressor (TVS) diode in SMC package, with 6.0V reverse standoff voltage (VRWM), 10.3V max clamping voltage at 145.6A peak pulse current, and AEC-Q101 qualification for ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD protection in vehicle power-line and signal-line circuits.
For engineers reviewing the SMCJ6.0CAQ-13-F datasheet, SMCJ6.0CAQ-13-F pinout, SMCJ6.0CAQ-13-F application, or SMCJ6.0CAQ-13-F equivalent, this device serves as a high-energy, fast-response surge protector for 12V automotive subsystems including body control modules, infotainment power rails, CAN transceiver interfaces, and sensor supply lines where clamping performance, low leakage, and IATF 16949 traceability are critical.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering consistent clamping behavior during negative and positive transients per ISO7637-2 Pulse 1 (−100V), Pulse 2a (+50V), Pulse 3a (−150V), and Pulse 3b (+100V). Its glass-passivated junction ensures stable breakdown and low capacitance (≈1000 pF at 0 V, 1 MHz).
Designed for automotive-grade reliability, it features −55°C to +150°C operating junction temperature range, 200A non-repetitive forward surge capability (8.3 ms half-sine), and 5.0W steady-state power dissipation at TL = +75°C - enabling robust placement near ECU power inputs without thermal derating concerns under typical under-hood conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W - sustains single-event surges up to 1500W without failure per 10×1000 µs waveform. |
| Reverse Standoff Voltage (VRWM) | 6.0 V - blocks normal 12V system operation while remaining fully inactive below threshold. |
| Max Clamping Voltage (VC) | 10.3 V @ 145.6 A - limits downstream voltage to safe levels during ISO7637-2 Pulse 1/3a events. |
| Breakdown Voltage (VBR) | 6.67–7.37 V @ 10 mA - ensures precise, repeatable turn-on with tight manufacturing tolerance. |
| Leakage Current (IR) | 1000 µA @ 6.0 V - minimal standby loss on 12V rail; avoids battery drain in always-on modules. |
| Operating Temperature | −55°C to +150°C - supports engine bay, transmission, and ADAS ECU mounting without derating. |
| AEC-Q101 Qualified | Yes - validated for automotive use with PPAP documentation and IATF 16949 manufacturing control. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic UL 94V-0 housing; cathode band omitted (bidirectional); 0.21 g mass; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals function identically - no polarity dependency; enables flexible PCB layout on bidirectional lines like LIN or unidirectional CAN stubs. |
| Case / Body | Thermal and mechanical interface | Exposed copper pad provides primary heat path to PCB; requires ≥25 mm² 2-oz copper pour for full 1500W pulse handling. |
Key Features
| Feature | Design Value |
|---|---|
| 1500W peak pulse rating | Enables single-device protection against worst-case ISO7637-2 Pulse 1 (−100V) and Pulse 3a (−150V) on 12V systems without parallel staging. |
| Glass-passivated die construction | Ensures long-term parameter stability and low leakage drift over 15+ year automotive service life under thermal cycling. |
| AEC-Q101 qualification & PPAP support | Meets OEM Tier-1 requirements for change control, lot traceability, and zero-defect manufacturing in safety-critical ECUs. |
| Lead-free, halogen-free, RoHS 3 compliant | Supports global automotive recycling mandates and eliminates brominated flame retardants in high-temp under-hood environments. |
Applications
| Body Control Module (BCM) Power Input | CAN Transceiver Protection |
|---|---|
|
Use Scenario: 12V supply line to BCM subjected to load dump and alternator ripple per ISO7637-2 Pulse 2a (+50V) and Pulse 3b (+100V). IC Role / Device Role / Timing Role: Primary clamping element placed upstream of DC/DC converter input to limit transient voltage before regulation. Use Value: Clamps to ≤10.3V at 145.6A, preventing overvoltage damage to buck controller ICs and ensuring uninterrupted microcontroller operation. |
Use Scenario: CAN_H/CAN_L differential pair exposed to ESD events per ISO10605 (±30kV contact discharge) and coupled transients. IC Role / Device Role / Timing Role: Bidirectional TVS shunting surge energy away from CAN transceiver I/O pins during fast-rising ESD pulses. Use Value: Sub-1 ns response time and symmetrical clamping preserve signal integrity while protecting PHY-level drivers from latch-up or gate oxide rupture. |
| Infotainment System USB Power Rail | Occupant Detection Sensor Supply |
|
Use Scenario: 5V/9V USB PD power delivery path in head unit, vulnerable to hot-plug transients and ground bounce. IC Role / Device Role / Timing Role: Secondary overvoltage clamp after primary DC/DC stage, safeguarding USB controller and Type-C port ICs. Use Value: 6.0V VRWM aligns with 5V rail margin; 10.3V VC prevents brownout or reset of USB enumeration logic during 100ns surges. |
Use Scenario: 3.3V supply to capacitive seat occupancy sensor IC subjected to cable discharge events in assembly/test. IC Role / Device Role / Timing Role: Low-capacitance (≈1000 pF) TVS placed directly at sensor IC VDD pin to absorb sub-100ns ESD spikes. Use Value: Minimal added capacitance avoids signal distortion on high-impedance sensing nodes while maintaining <1 µA leakage at 3.3V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC5.0-13-F | Lower 500W peak power; 5.0V VRWM; same SMC package. | Insufficient for ISO7637-2 Pulse 1/3a; limited to low-energy ESD-only zones. | Select only for cost-sensitive, non-safety-critical interior sensors with no load-dump exposure. |
| SMAJ6.0CA | 600W peak power; identical VRWM/VC but lower IPP (72.8A); legacy AEC-Q101 grade. | Lacks full ISO7637-2 Pulse 1 compliance margin; not PPAP-capable. | Acceptable for legacy designs where 1500W headroom is unnecessary and supply chain constraints exist. |
Compared with SAC5.0-13-F and SMAJ6.0CA, SMCJ6.0CAQ-13-F delivers 2.5× higher surge energy handling, certified PPAP documentation, and guaranteed performance across full ISO7637-2 pulse profiles - making it the only choice for new AEC-compliant 12V power rail designs requiring zero-margin transient immunity.

FAQ
What is the difference between SMCJ6.0CAQ-13-F and SMCJ6.0AQ-13-F?
The "C" suffix denotes bidirectional configuration: SMCJ6.0CAQ-13-F clamps symmetrically for both positive and negative transients, while SMCJ6.0AQ-13-F is unidirectional and requires correct polarity orientation. Bidirectional operation eliminates layout errors in differential or AC-coupled lines like CAN and LIN, and is mandatory for ISO10605 ESD testing where polarity is undefined.
Does SMCJ6.0CAQ-13-F require a heatsink for 1500W pulse handling?
No external heatsink is required for single-pulse 1500W events, provided the PCB uses ≥25 mm² of 2-ounce copper connected to both terminals. The SMC package's thermal resistance from junction-to-board is 15°C/W, and the 10×1000 µs pulse duration allows sufficient heat diffusion into the copper plane without exceeding 150°C junction temperature under standard JEDEC test conditions.
Can SMCJ6.0CAQ-13-F be used on a 24V truck system?
No - its 6.0V VRWM is designed exclusively for 12V nominal systems. For 24V applications, select SMCJ24CAQ-13-F (24V VRWM, 38.9V VC) or SMCJ28CAQ-13-F (28V VRWM, 45.4V VC), which maintain appropriate voltage margins above 24V system peaks (up to ~36V) while still clamping below IC absolute maximum ratings.
Is the marking code on SMCJ6.0CAQ-13-F traceable to date and lot?
Yes - the top-side marking "BDG" identifies the SMCJ6.0CAQ variant, and the date code "YWW" (e.g., "245" = 2022 Week 45) is laser-etched adjacent to it. Full lot traceability, including wafer fab, assembly, and test data, is available through Diodes' PPAP documentation and Aetrix's certified sourcing records upon request.
