Product details
Overview
SMAJ10CAQ-13-F from Diodes Incorporated is a bi-directional 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 for under-hood electronics protection against ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD events.
For engineers reviewing the SMAJ10CAQ-13-F datasheet, SMAJ10CAQ-13-F pinout, SMAJ10CAQ-13-F application, or SMAJ10CAQ-13-F equivalent, this part supports critical surge immunity design in automotive power line interfaces, infotainment supply rails, and ADAS sensor I/O protection where bidirectional clamping, low leakage (<0.5µA), and IATF 16949 traceable sourcing are required.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, delivering 400W peak pulse power per the 10×1000µs waveform, with clamping voltage tightly controlled at ≤17.0V to protect downstream 12V-rated ICs during load dump or inductive switching transients.
Its glass-passivated junction ensures stable breakdown behavior over -55°C to +175°C operating range, while the SMA package enables surface-mount integration into compact automotive PCB layouts with verified moisture sensitivity level 1 handling and RoHS-compliant matte tin plating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400W - sustains single 10×1000µs surges without failure in automotive load-dump scenarios |
| Reverse Standoff Voltage | 10V - blocks normal 12V system operation while triggering clamping above ~11.1V |
| Max Clamping Voltage | 17.0V @ 23.5A - limits transient voltage to safe margin below 20V-rated component thresholds |
| Breakdown Voltage | 11.1–12.3V @ 1mA - defines precise conduction onset for predictable protection timing |
| Leakage Current | <0.5µA @ 10V - avoids parasitic drain on always-on vehicle circuits |
| Operating Temperature | -55°C to +175°C - meets under-hood thermal requirements without derating |
Pinout & Package
Package: SMA (Surface Mount Assembly), molded plastic UL 94V-0 housing, 0.064g mass, cathode band omitted due to bi-directional construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Conducts during negative-going surges (e.g., ISO7637-2 Pulse 1, −100V) |
| Cathode | Transient current entry (positive polarity) | Conducts during positive-going surges (e.g., ISO7637-2 Pulse 2a, +50V) |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Enables single-device protection of AC-coupled or floating lines without polarity concerns |
| AEC-Q101 qualification | Validated reliability for automotive powertrain and chassis systems requiring PPAP documentation |
| Glass passivated die | Ensures long-term stability of VBR and leakage under thermal cycling and humidity stress |
| Lead-free & halogen-free | Complies with EU RoHS 3 and automotive "Green" standards (<900ppm Br/Cl, <1000ppm Sb) |
Applications
| Engine Control Unit (ECU) Power Input | Infotainment USB Data Lines |
|---|---|
Use Scenario: Protects 12V supply rail of engine control modules from ISO7637-2 Pulse 1 (−100V) and Pulse 3a (−150V) induced by alternator load dump or relay switching. IC Role / Device Role / Timing Role: Primary bidirectional clamping device placed upstream of DC/DC converters and microcontroller LDOs. Use Value: Limits transient voltage to ≤17.0V, preventing latch-up or gate oxide damage in 20V-max rated power management ICs. | Use Scenario: Shields high-speed USB 2.0 differential pairs in head units from ESD events per ISO10605 (±30kV air/contact discharge). IC Role / Device Role / Timing Role: Low-capacitance TVS placed adjacent to USB connector to clamp fast-rising ESD pulses before signal integrity degradation. Use Value: Sub-1µA leakage preserves bus termination bias; symmetrical clamping maintains differential signal balance during ±8kV contact discharge. |
| Radar Sensor Power Supply | Body Control Module (BCM) LIN Bus |
Use Scenario: Safeguards 5V/3.3V radar module power inputs against coupled transients from nearby high-current actuators in ADAS domain controllers. IC Role / Device Role / Timing Role: Secondary protection stage following primary fuse and common-mode choke, absorbing residual energy after filtering. Use Value: 400W rating handles repetitive 50V pulses (ISO7637-2 Pulse 2a) without thermal runaway in sealed radar enclosures. | Use Scenario: Protects LIN transceiver I/O pins from battery reverse connection and jump-start surges in door modules and seat controllers. IC Role / Device Role / Timing Role: Bi-directional TVS integrated into LIN bus ESD protection network with series resistors and filtering capacitors. Use Value: 10V standoff allows normal 12V LIN bus operation while clamping reverse transients to safe levels for 15V-rated transceivers. |
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 |
|---|---|---|---|
| SAC10-2/TR13 | Same 10V VRWM, but 300W PPK and higher 18.2V VC @ 22A | Limited to lower-energy transients; unsuitable for full ISO7637-2 Pulse 1 compliance | Select when cost sensitivity outweighs need for full 400W surge margin |
| SMCJ10CA | Same electrical specs but non-automotive grade; lacks AEC-Q101 and PPAP support | Not approved for production automotive programs requiring IATF 16949 traceability | Acceptable only for prototyping or non-safety-critical aftermarket designs |
Compared with SAC10-2/TR13 and SMCJ10CA, SMAJ10CAQ-13-F uniquely delivers certified 400W surge capability, AEC-Q101 validation, and full PPAP documentation-making it the only choice for Tier 1-supplied ECU, radar, and BCM designs requiring zero-defect reliability and audit-ready compliance.

FAQ
What does the 'C' suffix in SMAJ10CAQ-13-F signify?
The 'C' denotes bi-directional configuration, meaning the device provides symmetrical clamping for both positive and negative transients without polarity dependence. This differs from uni-directional variants (e.g., SMAJ10AQ-13-F) that require correct anode/cathode orientation and only clamp one polarity.
Is SMAJ10CAQ-13-F compatible with lead-free reflow processes?
Yes-it features matte tin lead-free plating qualified per MIL-STD-202, Method 208 and supports standard Pb-free reflow profiles up to 260°C peak temperature. Its moisture sensitivity level is rated at Level 1 per J-STD-020, eliminating bake requirements prior to assembly.
How does the 17.0V clamping voltage impact system-level protection design?
The 17.0V max clamping voltage at 23.5A ensures downstream components rated for 20V absolute maximum survive ISO7637-2 Pulse 1 (−100V) and Pulse 2a (+50V) events. Designers must verify that the protected IC's input capacitance and layout inductance do not cause overshoot beyond this limit during sub-100ns rise-time transients.
Can SMAJ10CAQ-13-F replace SMAJ10AQ-13-F in existing designs?
No-bi-directional SMAJ10CAQ-13-F cannot directly substitute uni-directional SMAJ10AQ-13-F without circuit review. The former conducts on both polarities and lacks a cathode band, altering PCB layout, grounding strategy, and fault current paths in DC-biased applications like 12V supply rails with ground-referenced loads.
