Product details
Overview
SMCJ9.0CAQ-13-F from Diodes Incorporated is a bidirectional 1500W automotive transient voltage suppressor (TVS) diode in SMC package, with 9.0V reverse standoff voltage, 10.0–11.1V breakdown range at 1.0mA, 15.4V max clamping voltage at 97.4A peak pulse current, and AEC-Q101 qualification for ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD protection in vehicle power line interfaces.
For engineers reviewing the SMCJ9.0CAQ-13-F datasheet, SMCJ9.0CAQ-13-F pinout, SMCJ9.0CAQ-13-F application, or SMCJ9.0CAQ-13-F equivalent, this part supports high-reliability surge suppression in 12V automotive systems where fast clamping (<1ns), low leakage (<10µA @ 9.0V), and IATF 16949-manufactured consistency are critical selection criteria.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal lines without polarity constraints. Its glass-passivated die construction ensures stable VBR tolerance (±10%) and robust surge endurance under repeated 10/1000µs transients.
Designed for automotive-grade reliability, it meets ISO7637-2 Pulse 1 (−100V), Pulse 2a (+50V), Pulse 3a (−150V), and Pulse 3b (+100V), while sustaining 30kV air/contact ESD per ISO10605 with 150pF/330Ω network - verified under AEC-Q101 stress conditions including temperature cycling and HTRB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - handles severe load dump and inductive switching surges without failure |
| Reverse Standoff Voltage | 9.0V - sets minimum operating voltage threshold before clamping activates |
| Breakdown Voltage Range | 10.0–11.1V @ 1.0mA - defines precise conduction onset with tight ±10% tolerance |
| Max Clamping Voltage | 15.4V @ 97.4A - limits protected circuit voltage during worst-case 10/1000µs transient |
| Leakage Current | ≤10µA @ 9.0V - ensures negligible standby power loss in always-on vehicle modules |
| Operating Temperature | −55°C to +150°C - supports under-hood placement in engine control units and body controllers |
Pinout & Package
Package: SMC (DO-214AB), surface-mount molded plastic housing with UL 94V-0 flammability rating, 0.21g mass, cathode band omitted (bidirectional configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient current path | Both terminals function identically - no polarity dependency enables flexible PCB layout |
| Case / Body | Thermal and mechanical interface | Exposed copper pad on underside provides primary thermal path to PCB copper pour |
Key Features

Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) LIN Bus |
|---|---|
Use Scenario: 12V battery feed to microcontroller power rail exposed to load dump and alternator ripple. IC Role / Device Role: Primary overvoltage clamp upstream of DC-DC converter input. Use Value: Limits transient voltage to ≤15.4V, preventing damage to 16V-rated input capacitors and LDO regulators. | Use Scenario: LIN physical layer transceiver interface subjected to ESD events during service port connection. IC Role / Device Role: Bidirectional line protector between transceiver and vehicle harness. Use Value: Clamps ±30kV contact discharge within 1ns, preserving signal integrity and avoiding bus lockup. |
| Automotive Camera Power Supply | Infotainment System USB VBUS Line |
Use Scenario: 12V-to-5V buck converter input powering rear-view camera module near trunk latch mechanism. IC Role / Device Role: Secondary surge suppressor after main fuse, guarding against mechanical switch arcing. Use Value: Withstands repetitive 50V Pulse 2a transients from solenoid actuation without parameter shift. | Use Scenario: USB Type-A VBUS line in center console exposed to hot-plug and cable-induced surges. IC Role / Device Role: Low-capacitance (<100pF) overvoltage guard before USB controller IC. Use Value: Maintains <10µA leakage at 5V nominal, avoiding false disconnect detection while clamping to 15.4V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC9.0-C-TP | Same 9.0V VRWM, but 1000W PPK rating and SOD-123FL package (smaller footprint, lower thermal mass) | Limited to lower-energy transients (e.g., interior lighting circuits); not rated for ISO7637-2 Pulse 1 | Select when board space is constrained and surge severity is limited to ISO10605 only |
| SMCJ9.0CA | Identical electrical specs but non-automotive grade (no AEC-Q101, no PPAP, standard RoHS only) | Not approved for safety-critical vehicle systems; unsuitable for OEM production requiring change control | Select only for prototyping or non-automotive industrial applications |
Compared with SAC9.0-C-TP and SMCJ9.0CA, the SMCJ9.0CAQ-13-F delivers higher surge margin (1500W vs. 1000W), certified automotive qualification, and traceable IATF 16949 sourcing - making it the sole choice for production ECUs and BCMs requiring ISO7637-2 compliance.

FAQ
What does the "Q" suffix signify in SMCJ9.0CAQ-13-F?
The "Q" denotes AEC-Q101 qualification - confirming that the device has passed stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing per automotive reliability standards. It also indicates PPAP capability and manufacturing in IATF 16949-certified facilities, required for Tier 1 automotive supply chains.
Is SMCJ9.0CAQ-13-F unidirectional or bidirectional?
It is bidirectional, indicated by the "C" in the part number (SMCJ9.0CAQ-13-F). This means it clamps symmetrically for both positive and negative transients, with no cathode marking on the package. It is electrically identical in both directions, making it suitable for protecting AC-coupled lines or floating nodes without polarity constraints.
What is the maximum clamping voltage at rated peak current?
The maximum clamping voltage is 15.4V at 97.4A peak pulse current, measured using the standardized 10/1000µs double-exponential waveform. This value is guaranteed across the full operating temperature range (−55°C to +150°C) and ensures downstream 16V-rated components remain within safe operating limits during worst-case transients.
Can SMCJ9.0CAQ-13-F replace SMCJ9.0A-13-F in an existing design?
No - SMCJ9.0A-13-F is unidirectional (no "C"), while SMCJ9.0CAQ-13-F is bidirectional. Substituting without circuit review risks improper clamping on negative transients. Additionally, the "Q" suffix confirms AEC-Q101 qualification absent in the non-Q version, so replacement requires revalidation for automotive applications per ISO7637-2 test plans.
