Product details
Overview
SMBJ6.0CAQ-13-F from Diodes Incorporated is a bi-directional 600W automotive transient voltage suppressor (TVS) diode in SMB package, with 6.0V reverse standoff voltage (VRWM), 10.3V max clamping voltage (VC) at 58.3A peak pulse current (IPP), and AEC-Q101 qualification for under-hood power line protection against ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD events.
For engineers reviewing the SMBJ6.0CAQ-13-F datasheet, SMBJ6.0CAQ-13-F pinout, SMBJ6.0CAQ-13-F application, or SMBJ6.0CAQ-13-F equivalent, this part supports design of robust automotive power rail surge protection where precise clamping, low leakage (<800 µA @ VRWM), and IATF 16949 traceable sourcing are required.
Technical Context
This bi-directional TVS operates symmetrically across both polarities to clamp transients on unidirectional or bidirectional signal/power lines. Its 6.0V VRWM ensures compatibility with 5V–12V automotive subsystems while maintaining margin above nominal battery voltage (13.5V), and its 10.3V VC at 58.3A provides defined overvoltage limiting during ISO7637-2 Pulse 3b (+150V) events.
Thermal performance is characterized by 5.0W steady-state power dissipation at TL = +75°C and 4.8W/°C derating above +25°C ambient. The device sustains 100A non-repetitive forward surge current (IFSM) per 8.3ms half-sine wave, validated under AEC-Q101 stress conditions including temperature cycling and HTRB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - Clamps 10×1000µs transients without failure in automotive load-dump or inductive switching scenarios |
| Reverse Standoff Voltage (VRWM) | 6.0V - Maximum continuous operating voltage before clamping begins; sets minimum system voltage margin |
| Clamping Voltage (VC) | 10.3V @ IPP = 58.3A - Defines worst-case protected-line voltage during ISO7637-2 Pulse 3b (150V) event |
| Peak Pulse Current (IPP) | 58.3A - Sustained current level at which VC is measured; correlates directly to energy absorption capability |
| Leakage Current (IR) | <800 µA @ VRWM - Ensures minimal quiescent power loss in always-on vehicle modules |
| Operating Temperature | −55°C to +175°C - Validated for engine compartment mounting with full electrical performance across range |
Pinout & Package
Package: SMB (Surface-Mount Small Outline), molded plastic body with UL 94V-0 flammability rating, 0.1g mass, matte tin-plated terminals solderable per MIL-STD-202 Method 208. Bi-directional construction eliminates cathode marking; no polarity indicator.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path (bidirectional) | Connects to protected line; conducts during negative transients and positive transients equally |
| Cathode | Transient return path (bidirectional) | Connects to ground or reference plane; completes symmetrical clamping loop for both polarities |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power | Enables single-device protection against ISO7637-2 Pulse 1 (−150V) and Pulse 3b (+150V) without cascaded staging |
| AEC-Q101 qualified | Validated for automotive under-hood use with zero defects in HTGB, TC, and HTRB stress tests |
| Bi-directional architecture | Eliminates need for dual-diode configurations on AC-coupled or floating bus lines (e.g., LIN, CAN FD stubs) |
| RoHS 3 & Halogen-free | Complies with EU Directive 2015/863/EU and Diodes' "Green" definition (Br+Cl <1500ppm, Sb <1000ppm) |
Applications
| Body Control Module (BCM) Power Input | Infotainment Head Unit DC Supply |
|---|---|
Use Scenario: 12V battery feed to BCM subjected to load dump and alternator ripple. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main VBAT rail upstream of DC-DC converters. Use Value: Limits transient excursions to ≤10.3V, preventing latch-up or damage to 12V-input PMICs and microcontrollers. | Use Scenario: 12V input to infotainment head unit exposed to ISO7637-2 Pulse 2a (+112V) during ignition switching. IC Role / Device Role / Timing Role: First-stage transient suppression before bulk capacitance and LDO regulators. Use Value: Absorbs 58.3A peak current within 10×1000µs window, preserving downstream EMI filter integrity. |
| ADAS Camera Module Power Line | Electric Power Steering (EPS) Sensor Interface |
Use Scenario: 5V supply rail for CMOS image sensor in rear-view camera exposed to ESD per ISO10605 (30kV contact discharge). IC Role / Device Role / Timing Role: Fast-response clamping element placed adjacent to connector entry point. Use Value: Sub-1ns response time limits voltage overshoot to 10.3V, protecting 1.8V/3.3V image sensor I/O pins. | Use Scenario: 12V auxiliary supply to torque sensor in EPS system subjected to Pulse 3a (−220V) during motor commutation. IC Role / Device Role / Timing Role: Bidirectional clamp on isolated sensor supply referenced to chassis ground. Use Value: Symmetric clamping prevents reverse-bias breakdown of isolated DC-DC feedback optocouplers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0C-13-F (ON Semiconductor) | Same VRWM (6.0V), VC = 10.5V @ 58A, AEC-Q101 qualified but PPAP not explicitly stated | Lacks documented IATF 16949 manufacturing certification and PPAP capability | Select when cost sensitivity outweighs full automotive change control requirements |
| TPSMF6.0A (STMicroelectronics) | Lower PPK (400W), same VRWM (6.0V), VC = 10.5V @ 38A, AEC-Q101 qualified | Insufficient energy handling for ISO7637-2 Pulse 1 (−150V) compliance in high-inductance harnesses | Select only for low-energy ESD-only zones (e.g., USB-C port protection) |
Compared with SMBJ6.0C-13-F and TPSMF6.0A, SMBJ6.0CAQ-13-F uniquely combines 600W rating, full PPAP support, and IATF 16949 traceability-making it the only option qualified for safety-critical power rail protection in Tier 1 automotive ECUs.

FAQ
What does the "AQ" suffix signify in SMBJ6.0CAQ-13-F?
The "AQ" suffix denotes AEC-Q101 qualification, PPAP capability, and manufacture in IATF 16949-certified facilities. It confirms full automotive-grade process control, including temperature cycling, highly accelerated life testing, and statistical process monitoring-not just standard commercial reliability screening.
Can SMBJ6.0CAQ-13-F be used in place of a unidirectional SMBJ6.0AQ-13-F?
No-SMBJ6.0CAQ-13-F is bi-directional (denoted by "C") and lacks cathode polarity marking, whereas SMBJ6.0AQ-13-F is unidirectional with explicit anode/cathode orientation. Substitution requires circuit-level validation of reverse-polarity transient paths and may compromise clamping symmetry on AC-coupled lines.
What is the maximum allowable PCB trace length between SMBJ6.0CAQ-13-F and protected IC inputs?
For effective ESD protection per ISO10605, PCB trace inductance must be minimized: maximum recommended distance is 5 mm from TVS cathode/anode pads to the protected IC's power/ground pins. Longer traces increase impedance, degrading clamping response and allowing voltage overshoot beyond 10.3V during 30kV contact discharge.
Does SMBJ6.0CAQ-13-F require derating for operation at +125°C ambient?
Yes-peak pulse power must be derated linearly above +25°C at 4.8W/°C. At +125°C ambient, usable PPK drops to 120W (600W − 4.8W/°C × 100°C). Steady-state power remains limited to 5.0W only at TL = +75°C; board-level thermal design must ensure lead temperature does not exceed this threshold.
