Product details
Overview
SMCJ54AQ-13-F from Diodes Incorporated is a unidirectional 1500W automotive transient voltage suppressor (TVS) diode with 54V reverse standoff voltage, 87.1V max clamping voltage at 17.2A peak pulse current, and AEC-Q101 qualification. It protects CAN, LIN, and power supply rails in engine control units, body control modules, and ADAS sensors against ISO7637-2 Pulse 1/2a/3a/3b transients and ISO10605 ESD events.
For engineers reviewing the SMCJ54AQ-13-F datasheet, SMCJ54AQ-13-F pinout, SMCJ54AQ-13-F application, or SMCJ54AQ-13-F equivalent, this device delivers verified clamping performance under automotive surge conditions, supports lead-free reflow assembly, and provides traceable IATF 16949-manufactured supply for production-grade automotive electronics design.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds 54V (VRWM), with breakdown occurring between 60.0V and 66.3V at 1mA test current. Its 87.1V clamping voltage limits downstream circuit stress during 10×1000μs transients up to 17.2A.
Designed for automotive environments, it sustains operation from –55°C to +175°C junction temperature, handles 200A non-repetitive forward surge (8.3ms half-sine), and maintains <0.5μA leakage at VRWM - critical for low-power always-on vehicle networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single 10×1000μs surges without failure in ISO7637-2 Pulse 3b (VS = +100V) testing |
| Reverse Standoff Voltage | 54V - sets minimum operating voltage threshold before clamping activates on 12V/24V automotive systems |
| Max Clamping Voltage | 87.1V @ 17.2A - defines absolute maximum voltage seen by protected ICs during worst-case transient |
| Breakdown Voltage | 60.0–66.3V @ 1mA - ensures reliable turn-on margin above VRWM to avoid premature conduction |
| Leakage Current | <0.5μA @ 54V - prevents battery drain in always-on modules like telematics and gateway ECUs |
| Operating Temperature | –55°C to +175°C - enables placement near high-heat sources such as power inverters or engine compartments |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 flammability rating, cathode band polarity indicator, and matte tin lead finish compliant with RoHS 3 and halogen-free "Green" requirements.
| 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 transient |
| Cathode | Protected line connection | Connected to the signal or power rail requiring protection (e.g., CAN_H, 12V supply input) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use with PPAP capability and IATF 16949 manufacturing - eliminates qualification overhead for Tier 1 suppliers |
| 1500W peak pulse rating | Withstands ISO7637-2 Pulse 1 (–100V) and Pulse 3a (–150V) without degradation - reduces need for redundant protection stages |
| Fast response time | <1ps avalanche turn-on - clamps before sensitive MCU I/O or transceiver inputs experience overvoltage damage |
| Lead-free & Green | RoHS 3 compliant with <900ppm Br/Cl and <1000ppm Sb - meets global automotive environmental mandates without solderability compromise |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|
Use Scenario: Protects 12V power input and sensor signal lines (e.g., MAP, TPS) from load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed at ECU power entry point to clamp transients before DC-DC converters and microcontrollers. Use Value: Limits voltage to ≤87.1V during 100V ISO7637-2 Pulse 3b, preventing latch-up or gate oxide rupture in 3.3V/5V logic supplies. |
Use Scenario: Shields LIN bus transceivers and door actuator drivers from battery disconnect spikes and ESD events. IC Role / Device Role / Timing Role: Mounted directly at LIN physical layer interface to absorb contact discharge per ISO10605 (30kV). Use Value: Maintains <0.5μA leakage at 12V standby, enabling BCM sleep current compliance below 100μA for EU CO₂ regulations. |
| Advanced Driver Assistance Systems (ADAS) | Infotainment Head Unit |
Use Scenario: Safeguards camera module power and FPD-Link III data lines from ignition-induced transients in front radar/camera harnesses. IC Role / Device Role / Timing Role: Paired with low-capacitance TVS on high-speed video lines to suppress sub-100ns surges without signal integrity loss. Use Value: 87.1V clamping ensures image sensor analog front-end remains within safe operating area during 50V ISO7637-2 Pulse 2a events. |
Use Scenario: Guards USB-C power delivery and HDMI interfaces against hot-plug surges and dashboard ESD. IC Role / Device Role / Timing Role: Positioned at USB-C VBUS input to limit overvoltage during 12V-to-5V buck converter fault conditions. Use Value: 17.2A peak pulse current rating handles 10×1000μs surges from nearby motor actuation noise coupling into infotainment harnesses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC54-13-F | Same 54V VRWM but lower 1000W PPK rating and 92V VC @ 12.5A | Limited to less severe transients (e.g., interior modules only); not rated for ISO7637-2 Pulse 1 | Select when cost sensitivity outweighs full powertrain-level surge immunity requirements |
| 1.5SMC54A-Q | Identical electrical specs but lacks AEC-Q101 certification and IATF 16949 traceability | Restricted to non-safety-critical consumer or industrial designs; not PPAP-capable | Choose only for prototyping or non-automotive applications where automotive qualification is unnecessary |
Compared with SAC54-13-F and 1.5SMC54A-Q, SMCJ54AQ-13-F uniquely combines 1500W surge capacity, AEC-Q101 validation, and full ISO7637-2/Pulse 1 compliance - making it the sole option for production ECU and ADAS power rail protection requiring zero field returns.

FAQ
What is the maximum clamping voltage of SMCJ54AQ-13-F at its rated peak pulse current?
The maximum clamping voltage (VC) is 87.1V at 17.2A peak pulse current, measured using the standard 10×1000μs waveform per REA and IEC 61000-4-5. This value is guaranteed across –55°C to +175°C junction temperature and defines the upper voltage limit imposed on protected circuits during surge events.
Is SMCJ54AQ-13-F suitable for bidirectional signal line protection like CAN bus?
No - SMCJ54AQ-13-F is unidirectional and intended for power rail or single-polarity signal protection. For CAN bus, use the bi-directional variant SMCJ54CAQ-13-F, which clamps symmetrically above and below ground and meets ISO11898-2 common-mode surge requirements.
Does SMCJ54AQ-13-F require derating at elevated ambient temperatures?
Yes - peak pulse power must be linearly derated above +25°C ambient per Figure 1 in DS40741. At +85°C ambient, maximum PPK drops to ~85% of 1500W (≈1275W), and at +125°C, it falls to ~55% (≈825W), based on thermal resistance and package limitations.
How does the SMCJ54AQ-13-F leakage current impact low-power automotive modules?
Its maximum reverse leakage is 0.5μA at 54V and +25°C, rising to ≤5μA at +125°C. This ensures compatibility with ultra-low-power wake-up circuits in gateways and telematics units, where total sleep current budgets often target <50μA for regulatory compliance.
