Product details
Overview
3.0SMCJ54AQ-13 from Diodes Incorporated is a unidirectional 3000W surface-mount transient voltage suppressor (TVS) diode with 54V reverse standoff voltage, 60.0–66.3V breakdown range at 1mA, and 87.1V max clamping voltage at 34.4A peak pulse current. It features glass-passivated die construction, AEC-Q101 qualification for automotive use, and IEC-61000-4-2 ESD protection (30kV air/30kV contact). It protects DC power rails in automotive infotainment power supplies.
For engineers reviewing the 3.0SMCJ54AQ-13 datasheet, 3.0SMCJ54AQ-13 pinout, 3.0SMCJ54AQ-13 application, or 3.0SMCJ54AQ-13 equivalent, key selection criteria include clamping voltage margin vs. protected IC VMAX, peak pulse current handling under ISO 7637-2 Pulse 1/2a/5a waveforms, unidirectional polarity alignment with DC rail topology, and SMC package thermal performance on 8mm² copper land.
Technical Context
This TVS operates as a voltage-clamped crowbar device during transients: below 54V it exhibits <5µA leakage; above 60V it avalanches sharply to limit voltage to ≤87.1V at 34.4A (10×1000µs waveform). Its glass-passivated junction ensures stable breakdown and low capacitance (<200pF typical), critical for fast-rising automotive load-dump surges.
The device is rated for -55°C to +150°C operating temperature and qualified to AEC-Q101 Rev G, confirming robustness against mechanical stress, temperature cycling, and high-humidity bias life testing-essential for under-hood and dashboard-mounted electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains 10×1000µs surge without failure; enables protection against ISO 7637-2 Pulse 5a (load dump) |
| Reverse Standoff Voltage (VRWM) | 54V - maximum continuous DC voltage before significant leakage; sets minimum system operating margin |
| Breakdown Voltage (VBR) | 60.0–66.3V @ 1mA - tight distribution ensures predictable turn-on across production lots |
| Max Clamping Voltage (VC) | 87.1V @ 34.4A - defines upper voltage bound seen by downstream ICs during worst-case surge |
| ESD Rating | IEC 61000-4-2: ±30kV air / ±30kV contact - exceeds automotive EMC test requirements for console interfaces |
| Operating Temperature | -55°C to +150°C - supports placement near engines, inverters, or battery management units |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with matte tin-plated leads; UL 94V-0 rated; 0.21g weight; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode-to-cathode conduction path during reverse-biased surge | Must connect to protected line; cathode ties to system ground or lower-potential rail |
| Anode | Reference terminal for clamping action | Connects to ground plane or return path; requires low-inductance layout to minimize clamping overshoot |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood use including temperature cycling, humidity bias, and mechanical shock |
| Glass-passivated junction | Eliminates surface contamination effects, ensuring stable VBR and low leakage over 15+ year service life |
| 30kV IEC 61000-4-2 ESD rating | Protects USB, CAN, or display interfaces from human-body discharge without external series resistance |
| Lead-free & halogen-free | Complies with RoHS 3 and automotive "Green" standards (<900ppm Br/Cl, <1000ppm Sb) |
Applications
| Automotive Infotainment Power Rail | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: 12V battery-fed head unit power supply exposed to ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 5a (load dump). IC Role / Device Role / Timing Role: Unidirectional TVS placed between input fuse and DC-DC converter input capacitor. Use Value: Clamps transients to ≤87.1V, preserving 100V-rated input capacitors and preventing DC-DC controller latch-up. |
Use Scenario: 24V digital input channel receiving signals from field sensors subject to lightning-induced surges. IC Role / Device Role / Timing Role: Primary surge clamp ahead of optocoupler or Schmitt-trigger input stage. Use Value: Absorbs 3000W pulses without degradation, maintaining signal integrity and eliminating need for secondary gas-tube backup. |
| Automotive Body Control Module (BCM) | Telecom PoE Interface Protection |
Use Scenario: LIN bus power domain sharing 12V rail with window lift motors and door lock actuators. IC Role / Device Role / Timing Role: Localized TVS on each LIN node's VCC line, adjacent to transceiver. Use Value: Limits voltage excursions to <87.1V during motor commutation noise, preventing LIN transceiver reset or data corruption. |
Use Scenario: 48V Power over Ethernet (PoE) injector output port subjected to cable discharge events. IC Role / Device Role / Timing Role: Secondary-level TVS on PSE output, downstream of primary MOV-based protection. Use Value: Provides precise clamping (±3.3V VBR tolerance) and low capacitance to avoid Ethernet signal integrity loss at 100MHz. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ54A-13-F | Lower peak power (600W), same VRWM/VBR/VC, SMB package (smaller footprint, lower thermal mass) | Insufficient for ISO 7637-2 Pulse 5a; limited to low-energy ESD or microsecond surges | Select only if system surge energy is confirmed <600W and PCB space is constrained |
| 1.5SMC54A-Q | Same 3000W rating and 54V VRWM, but non-automotive grade (no AEC-Q101); slightly higher VC (88.0V) | Lacks automotive qualification documentation and PPAP support; unsuitable for OEM BOMs requiring change control | Acceptable for industrial prototypes or non-safety-critical consumer designs where AEC-Q101 is not mandated |
Compared with SMBJ54A-13-F and 1.5SMC54A-Q, the 3.0SMCJ54AQ-13 uniquely delivers automotive-grade reliability, full 3000W surge capacity in the SMC form factor, and tighter clamping (87.1V) - making it the only choice for production automotive power rail protection requiring AEC-Q101 compliance and ISO 7637-2 Pulse 5a immunity.

FAQ
What does the 'Q' suffix in 3.0SMCJ54AQ-13 signify?
The 'Q' suffix indicates AEC-Q101 qualification per Rev G, including stress testing for temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. It confirms suitability for automotive applications requiring PPAP documentation and IATF 16949-manufactured lots.
Can 3.0SMCJ54AQ-13 be used in bidirectional configurations?
No - the 'A' in the part number denotes unidirectional operation, with a visible cathode band. Bidirectional variants (e.g., 3.0SMCJ54CA-13) lack polarity marking and conduct in both directions; substituting them requires verifying circuit topology and grounding scheme compatibility.
How does the SMC package affect thermal performance in high-surge applications?
The SMC package provides 8mm² thermal pad area per JEDEC standard, enabling 3000W pulse dissipation when mounted on ≥8mm² copper land. Derating begins above +25°C ambient per Fig. 1; at +125°C, peak power drops to ~1500W, requiring layout verification for sustained surge duty cycles.
Is 3.0SMCJ54AQ-13 compliant with RoHS 3 and automotive green standards?
Yes - it meets EU Directive 2015/863/EU (RoHS 3), contains <900ppm bromine and chlorine (total <1500ppm), and <1000ppm antimony, satisfying Diodes' "Green" definition and automotive environmental compliance requirements.
