Product details
Overview
SMCJ8.0CAQ-13-F from Diodes Incorporated is a bidirectional 1,500W automotive transient voltage suppressor (TVS) in SMC package, with 8.0V reverse standoff voltage, 13.6V max clamping voltage at 110.3A 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-line circuits.
For engineers reviewing the SMCJ8.0CAQ-13-F datasheet, SMCJ8.0CAQ-13-F pinout, SMCJ8.0CAQ-13-F application, or SMCJ8.0CAQ-13-F equivalent, this device is selected for robust surge immunity in 12V automotive subsystems where fast response (<1 ns), low clamping ratio (1.7× VRWM), and IATF 16949-manufactured reliability are required.
Technical Context
This bidirectional TVS diode operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal lines without polarity constraints. Its glass-passivated junction ensures stable breakdown behavior under repeated transients, and its 10×1000μs waveform-rated clamping performance meets stringent automotive surge test profiles.
The device delivers 1,500W peak pulse power dissipation with thermal derating above +25°C ambient, maintaining ≥75% of rated power up to +75°C lead temperature. Its 50μA max reverse leakage at VRWM supports low-power monitoring circuits without compromising standby current budgets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single 10×1000μs surges per ISO7637-2 without failure |
| Reverse Standoff Voltage | 8.0V - defines maximum continuous operating voltage before clamping onset |
| Max Clamping Voltage | 13.6V @ 110.3A - limits protected circuit voltage to safe level during worst-case surge |
| Breakdown Voltage Range | 8.89–9.83V @ 1.0mA - ensures tight VBR tolerance for predictable turn-on threshold |
| Peak Pulse Current | 110.3A - withstands ISO7637-2 Pulse 1 (−100V) and Pulse 3a (−150V) waveforms |
| Reverse Leakage | 50μA @ 8.0V - negligible loading on 12V supply rails or sensor bias networks |
| Operating Temperature | −55°C to +150°C - supports under-hood placement in engine control units and body modules |
Pinout & Package
Package: SMC (DO-214AB), surface-mount molded plastic housing with UL 94V-0 flammability rating, cathode band omitted due to bidirectional construction, 0.21g mass, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; no polarity dependency enables universal placement on differential or AC lines |
| Case (exposed pad) | Thermal conduction path | Integral copper slug transfers heat to PCB copper pour; requires minimum 25 mm² thermal pad for PM(AV) = 5W operation |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of CAN, LIN, or analog sensor lines without orientation constraints or external diode pairing |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and surge endurance per stress test plan |
| Glass-passivated die | Eliminates surface contamination effects, ensuring stable VBR over lifetime and humidity exposure |
| Lead-free & halogen-free | Complies with RoHS 3 and automotive green standards (<900ppm Br, <900ppm Cl, <1000ppm Sb) |
| Fast response time | Clamps within <1 ns of transient onset-critical for protecting high-speed MCU I/O and CAN transceivers |
Applications
| Infotainment Power Input Protection | Body Control Module (BCM) CAN Bus |
|---|---|
Use Scenario: 12V supply line to head unit exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Primary overvoltage clamp upstream of DC-DC converters and LDOs. Use Value: Limits input voltage to ≤13.6V during ISO7637-2 Pulse 1 (−100V), preventing regulator latch-up and downstream IC damage. | Use Scenario: CAN_H/CAN_L differential pair connecting gateway ECU to door module. IC Role / Device Role / Timing Role: Bidirectional transient suppressor placed across bus lines near connector. Use Value: Clamps ±15kV ESD (ISO10605) and ±100V Pulse 3b without distorting signal integrity or exceeding CAN common-mode range. |
| Engine Control Unit (ECU) Sensor Interface | ADAS Camera Power Line |
Use Scenario: 5V reference line feeding oxygen sensor or knock sensor in high-EMI engine bay. IC Role / Device Role / Timing Role: Low-leakage (50μA) standoff clamp preserving analog accuracy while blocking transients. Use Value: Maintains <0.1% reference error under steady state while suppressing ISO7637-2 Pulse 3a (−150V) surges. | Use Scenario: 12V power feed to 77GHz radar camera module mounted behind bumper. IC Role / Device Role / Timing Role: First-stage surge protector before secondary filtering and local regulation. Use Value: Absorbs 1500W peak energy from lightning-induced coupling, reducing downstream filter size by 40% versus lower-power TVS. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC8.0CA | Same 8.0V VRWM, but 1000W PPK and 90A IPP; smaller SOD-123FL package | Limited to lower-energy surges; unsuitable for full ISO7637-2 Pulse 1 compliance | Select when board space is constrained and surge threat level is limited to ISO10605 only |
| TPSMD8.0C | 8.0V VRWM, 1500W PPK, but 125°C max TJ (vs. 150°C) and non-AEC-Q101 | Not qualified for automotive production; restricted to industrial or consumer use | Select only for non-automotive designs where AEC-Q101 is not mandated |
Compared with SAC8.0CA and TPSMD8.0C, SMCJ8.0CAQ-13-F uniquely combines AEC-Q101 qualification, 1500W capability, and −55°C to +150°C operation-making it the only choice for production automotive ECUs requiring full ISO7637-2 compliance and extended temperature support.

FAQ
What does the 'C' suffix in SMCJ8.0CAQ-13-F indicate?
The 'C' denotes bidirectional configuration, meaning the device clamps symmetrically for both positive and negative transients-unlike unidirectional versions that require correct anode/cathode orientation. This eliminates polarity concerns during PCB layout and supports protection of AC-coupled interfaces like CAN or LIN without external circuitry.
Is SMCJ8.0CAQ-13-F compliant with RoHS 3 and automotive green standards?
Yes-it carries RoHS 3 (2015/863/EU) compliance with all applicable exemptions applied, and is halogen- and antimony-free per Diodes' definition: <900ppm bromine, <900ppm chlorine (total Br+Cl <1500ppm), and <1000ppm antimony compounds-verified via material declarations and third-party testing.
How does the SMC package support thermal management in high-power surge events?
The SMC (DO-214AB) package features an exposed copper slug that serves as the primary thermal path. When soldered to ≥25 mm² of 2-oz copper on the PCB, it maintains junction temperature below 150°C during 1500W pulses, enabling reliable operation without heatsinking-critical for compact automotive modules with limited airflow.
Can SMCJ8.0CAQ-13-F replace SMCJ8.0AQ in existing designs?
No-SMCJ8.0AQ is unidirectional and requires correct polarity placement; substituting the bidirectional SMCJ8.0CAQ-13-F would eliminate polarity constraints but may alter clamping symmetry in DC-biased circuits. Layout review and transient simulation are required before replacement, especially in power-rail applications with defined ground references.
