Product details
Overview
SMCJ9.0AQ-13-F from Diodes Incorporated is a unidirectional 1,500W automotive transient voltage suppressor (TVS) diode in SMC package, with 9.0V reverse standoff voltage, 10.0–11.1V breakdown range at 1.0mA, and 15.4V max clamping voltage at 97.4A peak pulse current. It protects CAN, LIN, and power supply lines in engine control units and body electronics against ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD surges.
For engineers reviewing the SMCJ9.0AQ-13-F datasheet, SMCJ9.0AQ-13-F pinout, SMCJ9.0AQ-13-F application, or SMCJ9.0AQ-13-F equivalent, key selection criteria include clamping voltage margin vs. system rail, AEC-Q101 qualification status, IATF 16949 manufacturing traceability, and compliance with ISO7637-2 Pulse 3a (−150V) and ISO10605 contact discharge (30kV).
Technical Context
This TVS operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds VRWM = 9.0V and fully clamps within <1 ns to limit transients to ≤15.4V at 97.4A (10/1000μs waveform). Its glass-passivated die ensures stable breakdown and low leakage (<10μA @ 9.0V).
Designed for automotive-grade reliability, it sustains 200A non-repetitive forward surge (8.3ms half-sine), derates linearly above +25°C ambient, and maintains operation from −55°C to +150°C junction temperature - meeting stringent under-hood thermal requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - withstands ISO7637-2 Pulse 3a (−150V) without failure |
| Reverse Standoff Voltage (VRWM) | 9.0V - sets minimum clamping threshold before avalanche conduction |
| Breakdown Voltage (VBR) | 10.0–11.1V @ 1.0mA - defines guaranteed conduction onset across temperature and lot |
| Max Clamping Voltage (VC) | 15.4V @ 97.4A - limits protected IC input voltage during worst-case transient |
| Leakage Current (IR) | <10μA @ 9.0V - avoids parasitic loading on 9V automotive rails |
| Operating Temperature | −55°C to +150°C - supports placement near engines, transmissions, and power inverters |
| AEC-Q101 Qualified | Yes - validated for automotive use with PPAP capability and IATF 16949 manufacturing |
Pinout & Package
Package: SMC (DO-214AB), molded plastic, UL 94V-0 rated, 0.21g weight, cathode band polarity indicator. Terminals are matte tin-plated, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Banded End) | Transient Current Sink | Connects to protected line; conducts surge current to ground during overvoltage |
| Anode | Reference / Ground Return | Must be tied to low-impedance chassis or power ground to ensure effective clamping |
Key Features
| Feature | Design Value |
|---|---|

| RoHS 3 & Halogen-Free | Meets EU Directive 2015/863/EU with Br+Cl <1500ppm and Sb <1000ppm - compliant for global vehicle production |
Applications
| Engine Control Unit (ECU) Power Input | CAN FD Data Line Protection |
|---|---|
Use Scenario: 12V battery-supplied microcontroller power rail exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS clamps negative transients (Pulse 1, −100V) and positive spikes (Pulse 2a, +50V) before they reach LDOs or MCU VDD pins. Use Value: Prevents latch-up or permanent damage to 3.3V/5V logic by limiting rail excursion to ≤15.4V during 100A surge events. | Use Scenario: High-speed CAN FD bus (5 Mbps) routed through vehicle harnesses subject to ESD and inductive coupling. IC Role / Device Role / Timing Role: Low-capacitance (≈100pF) unidirectional clamp placed between CANH/CANL and ground to shunt ESD without signal distortion. Use Value: Maintains signal integrity up to 5 Mbps while passing ISO10605 30kV contact discharge without bit errors or bus lockup. |
| Body Control Module (BCM) LIN Bus | Automotive Lighting Driver Supply |
Use Scenario: LIN slave node (e.g., door module) powered from 12V via local regulator, connected to long wiring harnesses. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbs Pulse 3b (+100V) induced by relay switching and ignition noise on LIN bus and VCC lines. Use Value: Eliminates need for external RC filters by clamping transients within 1 ns, preserving LIN timing accuracy (±1% baud tolerance). | Use Scenario: LED headlamp driver IC supplied from switched 12V rail, subject to cold-crank dips and load dump surges. IC Role / Device Role / Timing Role: Primary overvoltage protector upstream of buck controller, absorbing 1500W pulses without thermal runaway. Use Value: Enables single-stage protection architecture - reduces BOM count vs. multi-TVS or MOV+TVS solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC9.0 | Same 9.0V VRWM, but 1000W PPK rating and higher VC = 16.5V @ 60A | Limited to lower-energy transients (e.g., ISO7637-2 Pulse 2a only); not qualified to AEC-Q101 | Select only for cost-sensitive non-automotive industrial designs where full ISO7637-2 Pulse 3a immunity is not required. |
| SMCJ9.0A-Q | Identical electrical specs and AEC-Q101 qualification, but packaged in 5000-piece tape-and-reel (no -13-F suffix) | No functional difference; differs only in packaging quantity and reel orientation | Choose when volume procurement requires standard 5k reels or when legacy BOM references non-F suffix variant. |
Compared with SAC9.0 and SMCJ9.0A-Q, SMCJ9.0AQ-13-F uniquely combines 1500W surge capacity, AEC-Q101 certification, and 3000-piece tape-and-reel packaging optimized for SMT line efficiency and automotive traceability requirements.

FAQ
What is the maximum clamping voltage of SMCJ9.0AQ-13-F at its rated peak pulse current?
The maximum clamping voltage (VC) is 15.4V at 97.4A peak pulse current, measured using the standardized 10/1000μs double-exponential waveform per REA and IEC 61000-4-5. This value is guaranteed across the full operating temperature range (−55°C to +150°C) and represents the upper bound of voltage seen by downstream circuitry during worst-case transient events.
Is SMCJ9.0AQ-13-F suitable for bidirectional signal line protection such as USB or HDMI?
No - SMCJ9.0AQ-13-F is unidirectional and lacks symmetrical clamping behavior. For bidirectional data lines, Diodes' SMCJ9.0CQ-13-F (bidirectional variant) or dedicated low-capacitance ESD arrays like AP2172 series are required to avoid DC bias disruption and ensure balanced transient suppression on both polarities.
Does SMCJ9.0AQ-13-F require heatsinking in typical automotive PCB layouts?
No additional heatsink is required for single-pulse or low-duty-cycle surge events. Its 5.0W steady-state power dissipation rating at TL = +75°C and SMC package thermal resistance (RθJA ≈ 60°C/W) allow safe operation on standard 1-oz copper PCBs with ≥25 mm² thermal pad area. Derating applies only for repetitive surges exceeding 4 pulses/minute.
How does the "-13-F" suffix in SMCJ9.0AQ-13-F affect its electrical performance?
The "-13-F" suffix indicates SMC package in 3000-piece tape-and-reel format with embossed carrier tape (F-type) and standard Diodes marking. It has no impact on electrical parameters, AEC-Q101 qualification, or thermal performance - all specifications match the base SMCJ9.0AQ part number defined in DS40741 Rev. 8-2.
