Product details
Overview
SMAJ10AQ-13-F from Diodes Incorporated is a unidirectional 400W automotive transient voltage suppressor (TVS) diode with 10V reverse standoff voltage, 17.0V max clamping voltage at 23.5A peak pulse current, and AEC-Q101 qualification. It protects CAN, LIN, and sensor interface circuits in engine control units and body electronics against ISO7637-2 Pulse 1/2a/3a/3b transients and ISO10605 ESD events.
For engineers reviewing the SMAJ10AQ-13-F datasheet, SMAJ10AQ-13-F pinout, SMAJ10AQ-13-F application, or SMAJ10AQ-13-F equivalent, this device serves as a primary front-end surge protection component in 12V automotive power domains where clamping performance, low leakage (<0.5µA @ 10V), and IATF 16949 traceability are critical selection criteria.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp in series with automotive power rails or signal lines, activating only during negative transients exceeding its 11.1V minimum breakdown voltage. Its glass-passivated die ensures stable VBR tolerance (±10%) and low thermal resistance for reliable energy absorption under repetitive 8.3ms half-sine surges.
The device complies with ISO7637-2 Pulse 1 (–100V), Pulse 2a (+50V), Pulse 3a (–150V), and Pulse 3b (+100V) waveforms while maintaining <17.0V clamping at 23.5A - enabling robust protection of downstream 12V-rated ICs without overvoltage stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400W - absorbs single-event transients up to 400W without failure per IEC 61000-4-5 waveform |
| Reverse Standoff Voltage | 10V - blocks normal 12V system operation while remaining inactive below surge threshold |
| Max Clamping Voltage | 17.0V @ 23.5A - limits voltage seen by protected ICs to safe levels during ISO7637-2 Pulse 1/3a events |
| Breakdown Voltage | 11.1–12.3V @ 1.0mA - tight VBR range ensures predictable turn-on timing across temperature |
| Leakage Current | <0.5µA @ 10V - negligible standby power loss in always-on vehicle modules |
| Operating Temperature | –55°C to +175°C - supports under-hood placement in ECU, transmission control, and ADAS sensors |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, molded plastic UL 94V-0 housing, cathode band polarity indicator, 0.064g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| ISO10605/ISO7637-2 compliance | Rated for 30kV air/contact ESD and full suite of automotive surge pulses without derating |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|
Use Scenario: Protecting 12V power input and sensor supply lines from load dump and alternator ripple. IC Role / Device Role / Timing Role: Front-end transient clamp on main power rail upstream of DC-DC converters and microcontrollers. Use Value: Limits voltage excursion to ≤17.0V during –100V ISO7637-2 Pulse 1, preventing latch-up or damage to 16-bit MCUs and analog front-ends. |
Use Scenario: Shielding LIN bus transceivers and door module switches from ESD and cable discharge events. IC Role / Device Role / Timing Role: Signal-line TVS placed directly at connector entry point before transceiver input pins. Use Value: Clamps 30kV contact ESD to <17.0V within nanoseconds, preserving LIN physical layer integrity and avoiding communication reset. |
| CAN Transceiver Interface | ADAS Camera Power Input |
Use Scenario: Safeguarding high-speed CAN FD data lines against coupled transients from adjacent power wiring. IC Role / Device Role / Timing Role: Low-capacitance unidirectional clamp on CAN_H/CAN_L differential pair (anode grounded, cathode tied to line). Use Value: Adds <0.5µA leakage at 10V and no signal distortion at 5Mbps, meeting ISO 11898-2 common-mode immunity requirements. |
Use Scenario: Securing 12V input to image sensor power management ICs in rear-view and surround-view cameras. IC Role / Device Role / Timing Role: Primary surge absorber on camera module's main power feed, placed before bulk capacitance. Use Value: Withstands repeated 50V ISO7637-2 Pulse 2a events without degradation, ensuring continuous video output during ignition switching. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-13-F | No AEC-Q101 qualification; standard industrial grade; same electrical specs and package | Not approved for production automotive programs requiring PPAP or IATF 16949 traceability | Select only for non-automotive or prototype validation where qualification is not mandated |
| SMBJ10AQ-13-F | Same AEC-Q101 rating but SMB package (higher PPK = 600W, larger footprint, lower thermal resistance) | Better suited for higher-energy transients (e.g., 24V commercial truck systems) where PCB space allows | Choose when surge energy exceeds 400W or junction temperature rise must be minimized in high-density layouts |
Compared with SMAJ10AQ-13-F, SMAJ10A-13-F lacks automotive qualification documentation and supply chain controls, while SMBJ10AQ-13-F trades compactness for higher surge capacity - making the SMAJ10AQ-13-F optimal for cost- and space-constrained AEC-Q101-compliant 12V ECUs.

FAQ
What is the maximum clamping voltage of SMAJ10AQ-13-F at its rated peak pulse current?
The maximum clamping voltage is 17.0V at 23.5A peak pulse current, measured using the standardized 10×1000μs double-exponential waveform per IEC 61000-4-5. This value is guaranteed across the full operating temperature range (–55°C to +175°C) and defines the upper voltage limit imposed on protected circuitry during surge events.
Is SMAJ10AQ-13-F suitable for bidirectional signal line protection?
No - SMAJ10AQ-13-F is unidirectional and intended for DC-biased lines like power rails or CAN_H with ground-referenced cathode. For bidirectional protection (e.g., USB, HDMI, or symmetric data lines), the bi-directional variant SMAJ10CAQ-13-F must be used, which has identical standoff and clamping specs but symmetrical avalanche behavior.
How does the glass passivation affect long-term reliability in automotive environments?
Glass passivation provides hermetic die surface protection against moisture ingress, ionic contamination, and thermal stress-induced migration - critical for maintaining stable breakdown voltage and leakage current over 15+ years of operation in under-hood conditions with 85°C ambient and 175°C junction temperatures.
Can SMAJ10AQ-13-F replace SMAJ12AQ-13-F in a 12V system design?
No - SMAJ10AQ-13-F has a 10V standoff voltage and may conduct during normal 12V battery transients (e.g., cold-crank dips to 6–8V followed by recovery overshoot). SMAJ12AQ-13-F's 12V VRWM provides appropriate margin; substituting requires verifying that 10V standoff does not cause false triggering or excessive leakage in the specific application.
