Product details
Overview
SMCJ90AQ-13-F from Diodes Incorporated is a unidirectional 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 protection against ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD events.
For engineers reviewing the SMCJ90AQ-13-F datasheet, SMCJ90AQ-13-F pinout, SMCJ90AQ-13-F application, or SMCJ90AQ-13-F equivalent, this device delivers verified clamping performance in high-energy surge environments where fast response (<1 ns), low leakage (<0.5 µA @ 90V), and IATF 16949-manufactured reliability are mandatory for automotive power rail and signal line protection.
Technical Context
This TVS operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds 90V standoff and clamping within nanoseconds to limit transients to ≤146V. It handles 8.3ms half-sine surges up to 200A and supports continuous dissipation of 5W at lead temperature ≤75°C.
Designed for automotive-grade robustness, it features a molded SMC package rated UL 94V-0, moisture sensitivity level 1, and matte tin lead finish compliant with MIL-STD-202 solderability. Its cathode band polarity indicator enables unambiguous PCB orientation during automated assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single-event transients per 10×1000µs waveform without failure |
| Reverse Standoff Voltage | 90V - defines maximum continuous DC or RMS operating voltage before clamping initiates |
| Max Clamping Voltage | 146V @ 10.3A - limits downstream circuit voltage during worst-case ISO7637-2 Pulse 3a (-150V) |
| Breakdown Voltage | 100–111V @ 1mA - ensures reliable avalanche conduction onset above VRWM |
| Leakage Current | ≤0.5µA @ 90V - minimizes standby power loss and avoids false triggering in low-current systems |
| Operating Temp Range | -55°C to +175°C - supports engine bay placement with full electrical specs maintained |
| AEC-Q101 Qualified | Yes - validated for automotive use including temperature cycling, HTRB, and ESD stress per AEC standard |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 rating, 0.21g mass, cathode band marking, and matte tin-plated terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current return path during clamping | Connected to ground or low-side reference; completes surge current loop during reverse-biased transient |
| Cathode | High-side connection point | Connected to protected line (e.g., 12V battery rail); polarity band identifies this terminal on PCB |
Key Features
| Feature | Design Value |
|---|---|
| 1500W Peak Pulse Rating | Enables protection against severe load dump and inductive switching events in 12V/24V automotive systems |
| Fast <1 ns Response Time | Clamps before sensitive MCU or CAN transceiver inputs exceed absolute maximum ratings |

| RoHS 3 / Halogen-Free | Meets EU and global environmental mandates with <900ppm Br, <900ppm Cl, <1000ppm Sb |
| Low Capacitance (~100pF) | Preserves signal integrity on high-speed lines (e.g., LIN, CAN FD) without bandwidth degradation |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) LIN Bus |
|---|---|
Use Scenario: Protection of 12V supply input to microcontroller-based ECU against alternator load dump and ISO7637-2 Pulse 1 (-100V). IC Role / Device Role / Timing Role: Unidirectional TVS clamps negative transients while remaining non-conductive during normal operation. Use Value: Limits voltage to ≤146V, preventing damage to LDO regulators and MCU VDD pins rated for 16V absolute max. | Use Scenario: Surge suppression on LIN physical layer between gateway and door module over 15m harness. IC Role / Device Role / Timing Role: Low-capacitance TVS absorbs ISO10605 contact discharge (30kV) without distorting 19.2kbps data waveform. Use Value: Maintains LIN bus timing margins by limiting clamping-induced jitter and preserving rise/fall times. |
| Advanced Driver Assistance Systems (ADAS) Camera Power | Electric Power Steering (EPS) Motor Driver |
Use Scenario: Input protection for 5V camera module power rail exposed to ignition noise and relay switching spikes. IC Role / Device Role / Timing Role: Fast-response TVS shunts sub-100ns ESD events before image sensor or ISP ICs latch-up. Use Value: Prevents pixel corruption and frame loss by clamping transients below sensor's 6V IO tolerance. | Use Scenario: Protection of H-bridge gate driver supply against inductive kickback from 3-phase motor windings. IC Role / Device Role / Timing Role: High-energy TVS absorbs repetitive 200A surge currents during motor commutation. Use Value: Extends gate driver IC lifetime by limiting VDD overvoltage to safe levels during PWM transitions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC90-13-F | Same 90V VRWM but lower 1000W PPK rating and higher 158V VC @ 9.5A | Limited to less severe surge profiles (e.g., ISO7637-2 Pulse 3b only) | Select when cost sensitivity outweighs need for full 1500W margin in non-critical subsystems |
| SMCJ90A-Q | Identical electrical specs but non-tape-and-reel packaging (bulk) and no -13-F suffix | Not suitable for high-speed SMT production requiring 3,000-piece reel logistics | Choose only for prototyping or low-volume hand-soldered builds where reel compatibility is irrelevant |
Compared with SAC90-13-F and SMCJ90A-Q, SMCJ90AQ-13-F uniquely combines 1500W surge capacity, AEC-Q101 certification, and tape-and-reel packaging-making it the only option qualified for volume production of safety-critical automotive ECUs requiring PPAP documentation and IATF 16949 traceability.

FAQ
What is the maximum clamping voltage of SMCJ90AQ-13-F at its rated peak pulse current?
The maximum clamping voltage is 146V at 10.3A peak pulse current, measured under the standardized 10×1000µs waveform defined in REA and IEC 61000-4-5. This value is guaranteed across the full operating temperature range of -55°C to +175°C and ensures downstream components remain within safe voltage limits during surge events.
Is SMCJ90AQ-13-F suitable for bidirectional signal line protection?
No-SMCJ90AQ-13-F is unidirectional, indicated by the absence of "C" in its part number. For bidirectional protection (e.g., on CAN or USB lines), the correct variant is SMCJ90CAQ-13-F, which has symmetrical clamping in both polarities and no cathode band marking.
How does the SMC package affect thermal performance in high-power automotive layouts?
The SMC (DO-214AB) package provides a thermal resistance of approximately 40°C/W junction-to-lead when mounted on 1-inch² 2-oz copper pads. Its 0.21g mass and UL 94V-0 molding enable stable operation at 175°C junction temperature, but PCB copper area and airflow must be designed to maintain TL ≤75°C for full 5W steady-state dissipation.
Does SMCJ90AQ-13-F require derating for ambient temperatures above +25°C?
Yes-peak pulse power must be linearly derated above +25°C per the curve in Figure 1 of DS40741 Rev. 12-2: at +85°C ambient, PPK is reduced to ~85% of 1500W (1275W), and at +125°C, it drops to ~50% (750W). Derating applies only to non-repetitive pulses; steady-state power remains governed by lead temperature limits.
