Product details
Overview
SMBJ10AQ-13-F from Diodes Incorporated is a unidirectional 600W surface-mount automotive transient voltage suppressor (TVS) diode with 10V reverse standoff voltage (VRWM), 11.1V minimum breakdown voltage (VBR), and 17.0V maximum clamping voltage (VC) at 35.3A peak pulse current (IPP). It delivers AEC-Q101 qualification, ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD protection for automotive power line and signal line surge suppression.
For engineers reviewing the SMBJ10AQ-13-F datasheet, SMBJ10AQ-13-F pinout, SMBJ10AQ-13-F application, or SMBJ10AQ-13-F equivalent, this part supports critical design validation for automotive infotainment power rails, body control module inputs, CAN transceiver protection, and ADAS sensor interface surge immunity-where precise clamping voltage, low leakage (<0.5µA @ VRWM), and IATF 16949 traceable manufacturing are mandatory.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp in parallel with sensitive automotive electronics, activating only during overvoltage transients exceeding its 11.1–12.3V breakdown range. Its 17.0V clamping voltage at 35.3A ensures downstream ICs see limited stress under ISO7637-2 Pulse 1 (−150V) and Pulse 3b (+150V) waveforms.
Designed for operation from −55°C to +175°C junction temperature, it sustains 5.0W steady-state power dissipation at TL = +75°C and derates linearly above +25°C (4.8W/°C), enabling reliable placement near hot engine-control units without thermal runaway.
Key Specifications

|---|---|
| Peak Pulse Power | 600W - Withstands single 10×1000µs transients up to 35.3A without failure |
| Reverse Standoff Voltage (VRWM) | 10.0V - Blocks normal 12V automotive battery voltage with <0.5µA leakage |

|---|---|
|
Use Scenario: 12V supply input to head unit MCU and audio amplifier ICs exposed to load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between fuse output and DC-DC converter input to clamp overvoltage before regulation. Use Value: 17.0V clamping prevents latch-up or gate oxide rupture in 28nm automotive SoCs rated for 16V absolute max input. |
Use Scenario: CAN_H and CAN_L lines in gateway ECUs subjected to ±30kV contact discharge per ISO10605. IC Role / Device Role / Timing Role: Bi-directional clamping (via dual SMBJ10AQ or dedicated bi-dir variant) shunts ESD energy to ground before transceiver I/O pins. Use Value: Sub-1nS response time and 17.0V VC limit bus voltage excursion to within CAN FD physical layer tolerance (±40V). |
| Body Control Module Input Protection | ADAS Camera Sensor Interface |
|
Use Scenario: Wake-up input (e.g., door handle switch) connected to BCM microcontroller GPIO, subject to cable discharge events. IC Role / Device Role / Timing Role: Unidirectional TVS referenced to vehicle ground, absorbing negative-going pulses from ISO7637-2 Pulse 3a (−220V). Use Value: 100A IFSM rating ensures survival of repeated mechanical switch bounce-induced transients without parameter shift. |
Use Scenario: FPD-Link III or GMSL serial video interface between radar camera and domain controller, routed through harnesses. IC Role / Device Role / Timing Role: Low-capacitance TVS (typ. 100pF @ 0V) placed differential across data pair to suppress coupled surges without signal integrity loss. Use Value: Clamping action preserves eye diagram margin for 3Gbps serial links by limiting common-mode overshoot to <17V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-13-F (Diodes Inc.) | Lacks AEC-Q101 qualification and PPAP capability; same electrical specs but non-automotive grade | Acceptable for industrial or consumer prototypes; not approved for Tier-1 automotive production BOMs | Select only for cost-sensitive non-automotive designs where qualification is not required |
| SMAJ10A-Q (ON Semiconductor) | Lower 400W peak power; 18.2V clamping at 27.4A; identical VRWM and VBR range | Marginally adequate for ISO7637-2 Pulse 3b but insufficient for Pulse 1 (−150V) in high-impedance circuits | Use only where system-level testing confirms clamping margin meets OEM surge test limits |
Compared with SMBJ10AQ-13-F, the SMAJ10A-Q offers lower cost but sacrifices 200W peak power headroom and fails to meet AEC-Q101-making it unsuitable for production automotive ECUs requiring full ISO7637-2 compliance and audit-ready qualification records.

FAQ
What is the polarity configuration of SMBJ10AQ-13-F?
SMBJ10AQ-13-F is a unidirectional TVS diode with cathode band marking on the package top surface. It conducts only during reverse-biased overvoltage events-clamping positive transients on the cathode side to the anode (ground) while blocking normal forward-biased 12V operation. This configuration matches standard automotive power rail protection topology.
Does SMBJ10AQ-13-F require heatsinking in typical automotive applications?
No additional heatsink is required. The device dissipates only transient energy (non-repetitive), and its 5.0W steady-state power rating at TL = +75°C is sufficient for PCB copper pour thermal relief. Derating curves confirm >80% peak power retention at +100°C ambient, making it suitable for under-dash mounting without forced airflow.
How does SMBJ10AQ-13-F perform under repeated ISO7637-2 Pulse 3b exposure?
Per datasheet specifications, SMBJ10AQ-13-F is rated for non-repetitive pulses only (max 4 pulses/minute). For systems requiring repetitive surge immunity, designers must implement external current-limiting impedance or verify cumulative junction temperature rise remains below +175°C using thermal modeling with actual board layout and pulse repetition rate.
Can SMBJ10AQ-13-F be used to protect bidirectional data lines like LIN or CAN?
No-it is unidirectional and unsuitable for bidirectional bus protection without external circuitry. For LIN or CAN, use the bi-directional variant SMBJ10CAQ-13-F or place two SMBJ10AQ-13-F devices in series opposition. Direct substitution risks forward conduction during normal bus signaling and violates ISO11898-2 common-mode voltage limits.
