Product details
Overview
SMCJ7.0AQ-13-F from Diodes Incorporated is a unidirectional 1,500W automotive-grade transient voltage suppressor (TVS) diode in SMC package, with 7.0V reverse standoff voltage, 12.0V max clamping voltage at 125A peak pulse current, and AEC-Q101 qualification for ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD protection in vehicle power line and signal interface circuits.
For engineers reviewing the SMCJ7.0AQ-13-F datasheet, SMCJ7.0AQ-13-F pinout, SMCJ7.0AQ-13-F application, or SMCJ7.0AQ-13-F equivalent, this part is selected for high-energy surge immunity in 12V automotive subsystems where clamping voltage margin, fast response (<1 ns), and IATF 16949 traceability are critical design constraints.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds 7.0V standoff and fully clamps within nanoseconds to limit transients to ≤12.0V at 125A (10/1000μs waveform). Its glass-passivated junction ensures stable breakdown and low leakage (<200µA at VRWM).
Designed for automotive environments, it sustains operating junction temperatures from –55°C to +150°C and meets ISO7637-2 Pulse 1 (–100V), Pulse 2a (+50V), Pulse 3a (–150V), Pulse 3b (+100V), and ISO10605 ±30kV ESD requirements with 150pF/330Ω network.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - withstands high-energy transients per ISO7637-2 without failure |
| Reverse Standoff Voltage | 7.0V - sets minimum circuit operating voltage before clamping initiates |
| Max Clamping Voltage | 12.0V @ 125A - limits downstream IC voltage stress during 10/1000μs surge |
| Breakdown Voltage | 7.78–8.60V @ 10mA - tight VBR tolerance ensures predictable turn-on threshold |
| Leakage Current | ≤200µA @ 7.0V - minimizes standby power loss in always-on automotive modules |
| Package | SMC - surface-mount footprint compatible with automated assembly and thermal relief pads |
| AEC-Q101 Qualified | Yes - validated for automotive reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
SMCJ7.0AQ-13-F uses the industry-standard SMC (DO-214AB) plastic package: 6.90mm × 4.40mm body, 2.50mm pad pitch, cathode band marking on top surface. Terminals are matte tin-plated for RoHS-compliant soldering per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-impedance return path; defines conduction direction in unidirectional operation |
| Cathode | Protected line input | Connected to supply rail or signal line; absorbs positive transients toward ground via avalanche breakdown |
Key Features
| Feature | Design Value |
|---|---|
| 1,500W peak pulse rating | Enables robust protection against severe load dump and inductive switching events in 12V systems |
| Glass-passivated die construction | Improves long-term stability of breakdown voltage and leakage under thermal cycling and humidity |
| Fast response time (<1 ns) | Clamps ESD and fast-edge transients before sensitive downstream logic or analog circuitry is damaged |
| AEC-Q101 qualified & PPAP capable | Supports automotive production release with full change control, test data, and IATF 16949 traceability |
| RoHS 3 & Halogen-free "Green" | Meets EU environmental compliance with <900ppm Br, <900ppm Cl, <1000ppm Sb for end-of-life processing |
Applications
| Body Control Module (BCM) Power Input | Infotainment USB Data Line Protection |
|---|---|
Use Scenario: 12V battery feed to BCM microcontroller power rail exposed to load dump and jump-start surges. IC Role / Device Role: Unidirectional TVS clamp placed between fuse output and DC-DC input capacitor. Use Value: Limits transient voltage to ≤12.0V, preserving 16V-rated input capacitors and preventing brownout reset of MCU during ISO7637-2 Pulse 1 (–100V). | Use Scenario: USB 2.0 D+/D– lines routed near high-current motor drivers in head unit PCB. IC Role / Device Role: Bidirectional-capable layout (though SMCJ7.0AQ is unidirectional; used with series impedance for signal line). Use Value: Clamps ±30kV contact ESD per ISO10605 without signal distortion, leveraging <1 ns response to protect USB PHY transceivers. |
| Engine Control Unit (ECU) Sensor Supply | ADAS Camera Power Interface |
Use Scenario: 5V sensor bias rail feeding crankshaft position and oxygen sensors subject to ignition noise. IC Role / Device Role: TVS placed at connector entry point upstream of LDO regulator. Use Value: Suppresses ISO7637-2 Pulse 3a (–150V) spikes induced by solenoid switching, maintaining regulated 5V output within ±2%. | Use Scenario: 12V camera module power input exposed to cable discharge events and alternator ripple. IC Role / Device Role: Primary overvoltage clamp before buck converter and image sensor ASIC. Use Value: Absorbs 1500W pulses while holding clamped voltage below 12.0V, preventing latch-up in CMOS image sensor front-end. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC7.0 | Same 7.0V VRWM, but 400W rating and SMA package; lower IPP (36A) and higher VC (13.3V) | Not suitable for ISO7637-2 Pulse 1; limited to low-energy ESD and signal-line protection | Select only for cost-sensitive non-automotive consumer interfaces where 1500W surge immunity is unnecessary |
| SMCJ7.0A-Q | Identical electrical specs and AEC-Q101 qualification; differs only in tape-and-reel packaging (no -13-F suffix) | No functional difference; same automotive use cases and reliability performance | Prefer SMCJ7.0AQ-13-F for automated SMT placement requiring 3000-piece reel; otherwise functionally interchangeable |
Compared with SAC7.0 and SMCJ7.0A-Q, SMCJ7.0AQ-13-F uniquely delivers 1500W surge handling in an AEC-Q101-qualified SMC package with verified ISO7637-2 Pulse 1/2a/3a/3b compliance-making it the only choice for high-reliability 12V power rail protection in production vehicles.

FAQ
Is SMCJ7.0AQ-13-F bidirectional or unidirectional?
SMCJ7.0AQ-13-F is unidirectional. The absence of the "C" suffix (e.g., SMCJ7.0CAQ-13-F) confirms single-polarity operation: it clamps positive transients on the cathode side relative to anode (ground). Bidirectional variants require explicit "C" marking and exhibit symmetrical clamping for both polarities.
What is the maximum operating temperature for continuous use?
The device supports continuous operation from –55°C to +150°C junction temperature. At ambient temperatures above +25°C, derating applies: steady-state power dissipation drops linearly from 5.0W at TL = +75°C to zero at +150°C, per Fig. 6 in DS40741 Rev. 8-2.
Can SMCJ7.0AQ-13-F replace SMCJ7.0A in non-automotive designs?
Yes, electrically identical-but SMCJ7.0AQ-13-F carries AEC-Q101 qualification, PPAP documentation, and IATF 16949 manufacturing evidence not present in standard SMCJ7.0A. For non-automotive use, the "Q" grade offers enhanced reliability data and traceability, though at higher cost and longer lead times.
How does its clamping voltage compare to SMCJ7.5AQ-13-F?
SMCJ7.0AQ-13-F has VC = 12.0V @ 125A; SMCJ7.5AQ-13-F has VC = 12.9V @ 116.3A. The lower VRWM device achieves tighter clamping (0.9V lower) at higher peak current, making it preferable for 12V systems where margin below 13.0V is critical for downstream 16V-rated components.
