Product details
Overview
SMCJ11CAQ-13-F from Diodes Incorporated is a bidirectional 1,500W automotive transient voltage suppressor (TVS) diode in SMC package, with 11V reverse standoff voltage (VRWM), 18.2V max clamping voltage (VC) at 82.4A 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 SMCJ11CAQ-13-F datasheet, SMCJ11CAQ-13-F pinout, SMCJ11CAQ-13-F application, or SMCJ11CAQ-13-F equivalent, this part delivers verified clamping performance in 10/1000μs surge conditions, supports lead-free reflow assembly, and meets IATF 16949 manufacturing requirements for automotive-grade reliability and traceability.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling robust protection of differential or AC-coupled automotive signal lines without polarity dependency. Its glass-passivated junction ensures stable breakdown characteristics over temperature and lifetime.
The device responds within <1 ns to transients, clamping voltages to ≤18.2V at 82.4A (10×1000μs waveform), while maintaining <5μA reverse leakage at 11V and surviving 200A non-repetitive forward surge per 8.3ms half-sine wave - critical for battery rail and LIN/CAN node protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single high-energy surges per ISO7637-2 Pulse 1 (−100V) without failure |
| Reverse Standoff Voltage (VRWM) | 11.0V - defines maximum continuous operating voltage before significant leakage begins |
| Clamping Voltage (VC) | 18.2V @ IPP = 82.4A - limits downstream IC voltage during 10/1000μs transients |
| Breakdown Voltage (VBR) | 12.2–13.5V @ IT = 1.0mA - ensures reliable triggering margin above VRWM |
| Operating Temperature | −55°C to +150°C - supports engine compartment placement per AEC-Q101 stress requirements |
| Package | SMC (DO-214AB) - surface-mount footprint compatible with automated PCB assembly and thermal relief pads |
Pinout & Package
SMCJ11CAQ-13-F uses the SMC (DO-214AB) package: molded plastic body (UL 94V-0), cathode band omitted (bidirectional), matte tin-plated terminals, 0.21g weight, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals function identically - no polarity assignment required for layout or routing |
| Case / Body | Thermal mass & mechanical anchor | Provides primary heat dissipation path to PCB copper; requires ≥25 mm² thermal pad for PM(AV) = 5W derating |
Key Features
| Feature | Design Value |
|---|---|
| 1,500W peak pulse rating | Enables single-device protection against severe ISO7637-2 Pulse 1 (−100V) and Pulse 3a (−150V) transients on 12V systems |
| AEC-Q101 qualified | Validated for automotive use via stress testing including HTGB, TCT, HTRB, and ESD per JESD22-A114/115 |
| Glass-passivated die | Ensures stable VBR and low leakage (<5μA @ VRWM) across −55°C to +150°C operating range |
| Bidirectional configuration | Protects AC-coupled interfaces (e.g., LIN bus, sensor analog outputs) without polarity-sensitive placement |
Applications
| Automotive Power Distribution | LIN Bus Node Protection |
|---|---|
Use Scenario: 12V battery rail input to body control module (BCM) exposed to load dump and alternator switching noise. IC Role / Device Role: Primary TVS clamp limiting transient voltage to <18.2V during ISO7637-2 Pulse 1 (−100V). Use Value: Prevents damage to downstream DC/DC converters and microcontrollers rated for ≤20V absolute maximum. |
Use Scenario: LIN transceiver interface connected to vehicle harness subject to ESD and coupled noise. IC Role / Device Role: Bidirectional clamping element absorbing ±30kV contact discharge per ISO10605. Use Value: Maintains LIN signal integrity by holding line voltage within ±18.2V during fast transients, avoiding false frame errors. |
| Engine Control Unit (ECU) Sensor Inputs | Automotive Lighting Driver Outputs |
Use Scenario: Analog sensor inputs (e.g., MAP, coolant temp) routed through long harnesses near ignition systems. IC Role / Device Role: Low-capacitance (<100pF) bidirectional TVS suppressing coupled spikes without distorting DC-coupled signals. Use Value: Preserves sensor accuracy by limiting transient-induced offset shifts and preventing ADC saturation. |
Use Scenario: High-side LED driver output driving headlamp modules subjected to back-EMF and hot-swap events. IC Role / Device Role: Clamp protecting MOSFET drain from inductive kickback exceeding 100V. Use Value: Eliminates need for external snubbers by absorbing 1500W pulses, reducing BOM count and board space. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC11CA-13-F | Same VRWM (11V), lower PPK (600W), higher VC (20.0V @ 30A) | Rated for consumer/industrial use only; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and surge energy requirements |
| SMCJ11CA | Identical electrical specs, but lacks "Q" suffix - not PPAP-capable or manufactured in IATF 16949 facility | No change control documentation or automotive-specific traceability | Use only in non-automotive designs where supply chain audit and change notification are not required |
Compared with SAC11CA-13-F and SMCJ11CA, the SMCJ11CAQ-13-F uniquely combines 1500W surge capability, AEC-Q101 qualification, and IATF 16949 production - making it the sole choice for safety-critical automotive power rails requiring full PPAP compliance and zero-defect traceability.

FAQ
What does the "Q" suffix in SMCJ11CAQ-13-F signify?
The "Q" denotes full automotive qualification: AEC-Q101 stress testing, PPAP documentation readiness, and manufacturing in an IATF 16949-certified facility. It guarantees change control, lot traceability, and zero-defect processes required for Tier 1 automotive supply chains - distinct from industrial-grade SMCJ11CA variants.
Can SMCJ11CAQ-13-F replace unidirectional TVS diodes in existing designs?
No - SMCJ11CAQ-13-F is bidirectional and lacks polarity marking; substituting it for a unidirectional device (e.g., SMCJ11AQ-13-F) risks incorrect clamping behavior on DC-biased lines. Use only where symmetrical protection is required, such as AC-coupled buses or dual-rail power monitoring circuits.
What is the maximum recommended PCB copper area for thermal management?
For continuous 5W steady-state dissipation at TL = +75°C, Diodes specifies ≥25 mm² of 2-oz copper connected to both terminals via multiple thermal vias. The SMC package's case serves as the primary thermal path; insufficient copper causes premature thermal shutdown during repetitive surges.
Does SMCJ11CAQ-13-F meet ISO16750-2 for road vehicle environmental conditions?
Yes - its AEC-Q101 qualification covers electrical stress tests aligned with ISO16750-2 Section 4 (supply voltage variations) and Section 5 (transient immunity), including load dump simulation. Full compliance requires system-level validation per vehicle manufacturer specifications, but the device satisfies core component-level requirements.
