Product details
Overview
SMCJ90CAQ-13-F from Diodes Incorporated is a bi-directional 1500W automotive transient voltage suppressor (TVS) diode with 90V reverse standoff voltage, 146V max clamping voltage at 10.3A peak pulse current, and AEC-Q101 qualification for under-hood electronics. It protects CAN/LIN bus interfaces and power supply rails against ISO7637-2 Pulse 1 (−100V), Pulse 3a (−150V), and ISO10605 ESD (±30kV).
For engineers reviewing the SMCJ90CAQ-13-F datasheet, SMCJ90CAQ-13-F pinout, SMCJ90CAQ-13-F application, or SMCJ90CAQ-13-F equivalent, key selection criteria include clamping voltage margin vs. system rail tolerance, bi-directional surge handling for AC-coupled data lines, IATF 16949 traceability, and SMC package thermal performance in high-temperature engine compartments.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling protection of differential signal pairs like CAN H/L without polarity constraints. Its 1.0mA breakdown test current and 0.5µA max reverse leakage at 90V ensure minimal standby power loss in always-on vehicle modules.
The device uses silicon avalanche junction technology to achieve sub-nanosecond response to transients, clamping within 100ps of surge onset. Its 1500W peak pulse rating per 10×1000µs waveform supports repeated exposure to load dump and inductive switching events in 12V/24V automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single 10×1000µs surges up to 10.3A without failure |
| Reverse Standoff Voltage | 90V - blocks normal operation up to 90V DC before clamping activates |
| Max Clamping Voltage | 146V @ 10.3A - limits transient voltage to safe level for 100V-rated downstream ICs |
| Breakdown Voltage | 100–111V @ 1mA - ensures reliable turn-on above system overvoltage threshold |
| Operating Temperature | −55°C to +175°C - supports placement near engines or in battery enclosures |
| ESD Rating | ±30kV air/contact per ISO10605 - meets automotive interior and exterior ESD immunity requirements |
| Surge Compliance | ISO7637-2 Pulse 1 (−100V), Pulse 3a (−150V) - certified for power line transient immunity |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 flammability rating, cathode band omitted due to bi-directional symmetry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Conducts during negative surges; connects to protected line or ground return path |
| Cathode | Transient current entry (positive polarity) | Conducts during positive surges; connects to protected line or VBAT rail |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Enables single-device protection of AC-coupled buses (e.g., CAN, LIN) without polarity concerns |
| AEC-Q101 qualification | Validated for automotive use with temperature cycling, HTRB, and ESD stress per JEDEC standards |
| IATF 16949 manufacturing | Ensures PPAP documentation, change control, and lot traceability for OEM Tier-1 supply chains |
| Lead-free & green construction | Meets RoHS 3 and halogen-free requirements (<900ppm Br/Cl, <1000ppm Sb) for global vehicle compliance |
| Low capacitance | Typical 100pF at 0V bias - avoids signal integrity degradation on 500kbps CAN FD links |
Applications
| Infotainment Head Unit Power Input | CAN FD Gateway Module |
|---|---|
Use Scenario: 12V supply line exposed to load dump and jump-start transients in central display units. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed between fuse and DC-DC converter input. Use Value: Limits voltage to ≤146V during −100V ISO7637-2 Pulse 1, preventing damage to 100V-rated buck controller MOSFETs. | Use Scenario: Protection of CAN FD transceiver PHY pins against ESD and board-level coupling noise. IC Role / Device Role / Timing Role: Bi-directional shunt element across differential pair (CANH/CANL) referenced to chassis ground. Use Value: Sub-ns response clamps ±30kV ESD strikes to <150V, preserving transceiver common-mode range and bit error rate. |
| Body Control Module (BCM) LIN Bus | Electric Power Steering (EPS) Motor Driver Supply |
Use Scenario: LIN slave node (e.g., door module) connected to 12V battery via long harness susceptible to inductive kick. IC Role / Device Role / Timing Role: Low-leakage (0.5µA @ 90V) TVS placed at LIN transceiver input, minimizing quiescent current impact. Use Value: Withstands −150V ISO7637-2 Pulse 3a without latch-up, maintaining <100nA sleep current in vehicle-off state. | Use Scenario: 24V supply rail feeding H-bridge gate drivers in EPS motor control unit. IC Role / Device Role / Timing Role: Secondary clamping device downstream of primary TVS, absorbing residual energy after initial suppression. Use Value: 175°C max junction temperature enables mounting on same PCB as power stage, reducing thermal interface resistance and improving reliability. |
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 |
|---|---|---|---|
| SAC90CA-13-F | Same 90V standoff, but 1000W rating and 153V clamping at 9.8A | Lower surge capacity suits lower-risk subsystems (e.g., lighting controls) | Select when cost sensitivity outweighs need for full 1500W margin in non-critical zones |
| TPSMD90CA | 90V standoff, 1500W rating, but 145V clamping at 10.3A and −40°C to +150°C range | Limited high-temp capability excludes under-hood deployment | Prefer for cabin modules where 175°C operation is unnecessary and footprint compatibility exists |
Compared with SAC90CA-13-F and TPSMD90CA, SMCJ90CAQ-13-F delivers superior high-temperature resilience (175°C vs. 150°C), tighter clamping (146V vs. 145–153V), and full AEC-Q101/PPAP support-making it the only choice for safety-critical powertrain and chassis domains requiring IATF 16949 traceability.

FAQ
What does the 'C' suffix in SMCJ90CAQ-13-F indicate?
The 'C' denotes bi-directional configuration, meaning the device clamps transients of either polarity symmetrically across its terminals. This eliminates polarity marking requirements and enables direct placement on differential signal lines like CAN or LIN without orientation concerns, unlike uni-directional variants that require correct anode/cathode alignment relative to system ground.
How does SMCJ90CAQ-13-F differ from industrial-grade SMCJ90A?
SMCJ90CAQ-13-F adds AEC-Q101 qualification, IATF 16949 manufacturing, PPAP documentation, and extended temperature validation (−55°C to +175°C). Industrial SMCJ90A lacks automotive change control, fails ISO7637-2 Pulse 3a validation, and has no guaranteed lot traceability-making it unsuitable for OEM vehicle programs despite identical electrical specs.
Can this TVS be used on a 48V mild-hybrid power rail?
No-its 90V standoff and 146V clamping are designed for 12V/24V systems. For 48V architectures, Diodes' SMCJ130CAQ-13-F (130V standoff, 209V clamping) or SMCJ150CAQ-13-F (150V standoff, 243V clamping) are specified to maintain ≥20% margin above nominal 48V+25% tolerance (60V), ensuring reliable blocking during normal operation while clamping load dump events.
Is the SMC package thermally adequate for continuous 5W dissipation?
No-the SMCJ90CAQ-13-F's 5W steady-state rating applies only at TL = +75°C lead temperature, not ambient. In practice, PCB copper area, thermal vias, and airflow determine real-world derating; typical SMC layouts achieve ~2.5W at TA = +85°C. For sustained >2W dissipation, forced convection or external heatsinking is required to avoid exceeding 175°C junction limit.
