Product details
Overview
SMCJ54CAQ-13-F from Diodes Incorporated is a bi-directional 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 for under-hood powertrain and body control modules. It protects CAN/LIN bus lines and sensor interfaces against ISO7637-2 Pulse 1/2a/3a/3b surges and ISO10605 ESD events.
For engineers reviewing the SMCJ54CAQ-13-F datasheet, SMCJ54CAQ-13-F pinout, SMCJ54CAQ-13-F application, or SMCJ54CAQ-13-F equivalent, this device is selected for high-energy surge immunity in 12V/24V automotive subsystems where bidirectional clamping, low leakage (<0.5µA), and IATF 16949 traceable manufacturing are required.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, delivering identical clamping performance for positive and negative transients - critical for protecting differential buses like CAN FD and LIN without polarity bias. Its 10×1000µs waveform response ensures compliance with ISO7637-2 Pulse 3b (+100V) and Pulse 3a (−150V) test profiles.
The device features a low 1.0mA breakdown test current and 0.5µA max reverse leakage at VRWM, enabling minimal standby power impact in always-on vehicle networks. Thermal design leverages SMC package's 175°C junction rating and 5W steady-state dissipation at TL = +75°C for sustained surge recovery in engine bay environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single 10×1000µs surges up to 17.2A without failure |
| Reverse Standoff Voltage | 54.0V - defines maximum continuous operating voltage before clamping activation |
| Max Clamping Voltage | 87.1V @ 17.2A - limits downstream IC stress during ISO7637-2 Pulse 1 (−100V) |
| Breakdown Voltage | 60.0–66.3V @ 1.0mA - ensures reliable turn-on margin above VRWM for robust noise immunity |
| Leakage Current | <0.5µA @ 54V - prevents battery drain in always-on automotive modules |
| Operating Temp Range | −55°C to +175°C - supports placement near engines, transmissions, and power inverters |
| AEC-Q101 Qualified | Yes - validated for automotive use with PPAP documentation and IATF 16949 manufacturing |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic UL 94V-0 housing; cathode band omitted due to bi-directional symmetry; 0.21g weight; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Conducts during negative surges; symmetrical with Cathode for bidirectional operation |
| Cathode | Transient current entry (positive polarity) | Conducts during positive surges; electrically identical to Anode in bi-directional configuration |
Key Features
| Feature | Design Value |
|---|---|
| ISO10605 ESD protection | 30kV air/contact discharge - eliminates need for external ESD diodes on infotainment USB/CAN ports |
| Fast response time | <1.0ps - clamps transients before sensitive MCU I/O pins experience overvoltage damage |
| Lead-free & halogen-free | RoHS 3 / "Green" compliant - meets EU automotive material restrictions (Br+Cl <1500ppm) |
| Stable clamping under temp | Clamping voltage variation <±5% from −40°C to +125°C - ensures consistent protection across vehicle thermal zones |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|
Use Scenario: Protects 5V sensor supply rails and LIN bus transceivers from load dump and alternator ripple. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed directly at connector interface to shunt transients before reaching MCU GPIOs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC54-13-F | Same VRWM (54V), lower PPK (600W), higher VC (93.6V @ 10A) | Limited to non-critical 12V accessories; insufficient for ISO7637-2 Pulse 1 compliance | Select only when cost sensitivity outweighs surge energy requirements and board space allows parallel devices. |
| SMCJ54A-13-F | Uni-directional version; same clamping but no negative-polarity protection | Requires external polarity-reversal circuitry for full ISO7637-2 coverage | Use only in DC-biased circuits with known unidirectional surge direction, e.g., regulated 5V logic rails. |
Compared with SAC54-13-F and SMCJ54A-13-F, SMCJ54CAQ-13-F uniquely delivers certified 1500W bidirectional clamping with AEC-Q101 traceability - essential for powertrain and ADAS nodes where single-point failure must be avoided and regulatory audit trails are mandatory.

FAQ
What is the meaning of the 'C' suffix in SMCJ54CAQ-13-F?
The 'C' denotes bi-directional configuration, confirming symmetrical clamping behavior for both positive and negative transients - verified by identical breakdown voltage min/max (60.0–66.3V) and clamping voltage (87.1V) in either polarity per DS40741 Rev. 12–2 Table 1.
Can SMCJ54CAQ-13-F replace uni-directional TVS diodes in existing designs?
No - it cannot directly replace uni-directional parts without circuit review. Bi-directional operation eliminates polarity dependency but increases leakage path complexity; redesign is required to verify ground reference stability and avoid unintended conduction during normal operation.
Is the SMCJ54CAQ-13-F suitable for 48V mild-hybrid systems?
No - its 54V VRWM and 87.1V clamping are optimized for 12V/24V architectures. For 48V systems, Diodes' SMD15T58A (58V VRWM, 93.6V VC) or SMAJ64A (64V VRWM) are validated alternatives per ISO7637-3 Pulse 5a/b requirements.
Does this part require derating at elevated ambient temperatures?
Yes - peak pulse power must be linearly derated above +25°C ambient per Figure 1: at +85°C TA, maximum PPK drops to 1050W (70% of rated 1500W), directly impacting survivability of repeated ISO7637-2 Pulse 3 events in under-hood locations.
