Product details
Overview
3.0SMCJ60CAQ-13 from Diodes Incorporated is a bi-directional automotive-grade transient voltage suppressor (TVS) diode in SMC package, rated for 3000W peak pulse power, 60V reverse standoff voltage (VRWM), and 96.8V max clamping voltage (VC) at 31.0A IPP under 10/1000μs waveform. It protects CAN, LIN, and power-line circuits in engine control units and body electronics against ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD surges.
For engineers reviewing the 3.0SMCJ60CAQ-13 datasheet, 3.0SMCJ60CAQ-13 pinout, 3.0SMCJ60CAQ-13 application, or 3.0SMCJ60CAQ-13 equivalent, this AEC-Q101 qualified TVS offers verified clamping performance, IATF16949-manufactured traceability, and RoHS/halogen-free compliance critical for automotive front-end protection design.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling robust protection of differential buses like CAN FD without polarity dependency. Its 60V VRWM ensures compatibility with 48V and 24V automotive systems while maintaining margin above nominal rail voltages.
The device delivers 31.0A peak pulse current (IPP) at 96.8V clamping under standardized 10×1000μs surge waveform, with <2.0µA reverse leakage at VRWM and -55°C to +175°C operating junction temperature range-meeting under-hood thermal requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains high-energy transients per ISO7637-2 Pulse 3b (+150V) without failure |
| Reverse Standoff Voltage (VRWM) | 60V - blocks normal 48V system operation while triggering only during overvoltage events |
| Max Clamping Voltage (VC) | 96.8V @ 31.0A IPP - limits downstream IC voltage stress below 100V during worst-case surge |
| Breakdown Voltage (VBR) | 66.7–73.7V @ 1.0mA - ensures reliable turn-on with controlled voltage margin above VRWM |
| Peak Forward Surge Current (IFSM) | 300A @ 8.3ms - handles repetitive load dump energy without bond wire fusing |
| Operating Temperature Range | -55°C to +175°C - supports placement near engines, transmissions, and power inverters |
| AEC-Q101 Qualified | Yes - validated for automotive reliability including HTOL, TCT, and ESD testing per AEC standard |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic UL 94V-0 housing; weight ≈0.21g; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode Band (Marked End) | Anode Terminal (Bi-directional) | Identifies terminal orientation; in bi-directional configuration, both ends function identically as symmetrical surge paths |
| Opposite End | Cathode Terminal (Bi-directional) | Electrically identical to marked end; no polarity dependence enables simplified PCB layout on differential lines |
Key Features
| Feature | Design Value |
|---|---|
| 3000W Peak Pulse Power | Enables single-device protection against ISO7637-2 Pulse 1 (-150V) and Pulse 3a (-220V) without derating |
| AEC-Q101 Qualification | Validated for automotive use with PPAP capability and IATF16949 manufacturing control |
| Bi-directional Symmetry | Eliminates polarity concerns on CAN/LIN buses and AC-coupled signal lines |
| RoHS & Halogen-Free | Meets EU Directive 2015/863/EU with <900ppm Br, <900ppm Cl, <1000ppm Sb - compliant for global Tier 1 supply chains |
| Low Clamping Ratio (VC/VRWM) | 1.61 - tight voltage margin reduces risk of downstream IC latch-up or damage during surge events |
Applications
| Engine Control Unit (ECU) Power Input | CAN FD Bus Protection |
|---|---|
Use Scenario: Protects 12V/48V power rails feeding microcontrollers and drivers in engine bay ECUs exposed to load dump and alternator transients. IC Role / Device Role: Primary front-end TVS clamp placed before DC-DC converters and LDOs. Use Value: Withstands 300A IFSM and clamps to 96.8V, preventing >100V stress on downstream 100V-rated input capacitors and regulators. |
Use Scenario: Shields high-speed CAN FD transceivers (e.g., TCAN1042-Q1) from ESD and coupled noise on vehicle wiring harnesses. IC Role / Device Role: Bi-directional line protector on CANH/CANL differential pair, mounted at connector entry point. Use Value: Symmetric clamping ensures equal protection regardless of transient polarity; 31.0A IPP handles ISO10605 ±30kV contact discharge without degradation. |
| Body Control Module (BCM) LIN Bus | ADAS Camera Power Line |
Use Scenario: Secures LIN bus nodes (e.g., door modules, seat controllers) against battery disconnect spikes and ground bounce in chassis networks. IC Role / Device Role: Low-leakage (≤2µA @ 60V) TVS placed directly at LIN transceiver pins. Use Value: 60V VRWM aligns with 12V system nominal; 96.8V VC ensures LIN PHY ICs (e.g., TLE7250) remain within absolute maximum ratings during ISO7637-2 Pulse 2a (+112V). |
Use Scenario: Guards 12V power input to 5MP+ automotive cameras in front/rear/surround-view systems subjected to vibration-induced arcing and hot-swap transients. IC Role / Device Role: Secondary surge clamp after primary fuse, located adjacent to image sensor power domain. Use Value: -55°C to +175°C TJ range supports operation behind headlamps or grilles; AEC-Q101 qualification ensures field reliability over 15-year vehicle lifecycle. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA | 2000W PPK, same VRWM/VC, but SMB package (smaller footprint, lower IFSM = 200A) | Limited to lower-energy transients; unsuitable for load dump in 48V systems | Select when board space is constrained and surge energy is limited to ISO10605 only |
| 1.5SMCJ60CA | 1500W PPK, same VRWM/VC, SMC package but lower power rating and IFSM = 200A | Inadequate for ISO7637-2 Pulse 1 (-150V) in heavy-duty vehicles | Use only in cost-sensitive 12V body electronics where full 3000W rating is not required |
Compared with SMBJ60CA and 1.5SMCJ60CA, the 3.0SMCJ60CAQ-13 provides 50% higher peak power and 50% higher surge current handling-critical for protecting next-gen 48V mild-hybrid ECUs and ADAS power domains against worst-case load dump.

FAQ
What is the clamping voltage of 3.0SMCJ60CAQ-13 at its rated peak pulse current?
The maximum clamping voltage (VC) is 96.8V at 31.0A peak pulse current (IPP), measured using the standardized 10×1000μs waveform per Figure 4 in DS40742 Rev. 12–2. This value is guaranteed across -55°C to +175°C junction temperature and defines the upper voltage limit imposed on protected circuitry during surge events.
Is 3.0SMCJ60CAQ-13 unidirectional or bidirectional, and how is polarity identified?
It is bi-directional, indicated by the "C" suffix in the part number and confirmed by symmetric electrical characteristics in the datasheet. The cathode band marking identifies one terminal, but both terminals behave identically-no anode/cathode distinction applies during surge conduction, simplifying layout on differential buses like CAN.
Does 3.0SMCJ60CAQ-13 meet AEC-Q101 requirements for automotive use?
Yes-it is fully AEC-Q101 qualified, PPAP capable, and manufactured in IATF16949-certified facilities. Test validation includes high-temperature operating life (HTOL), temperature cycling (TCT), and ESD per HBM/MM/CDM models, ensuring reliability for under-hood and chassis applications over full vehicle lifecycles.
What is the maximum surge current the device can withstand without degradation?
The device sustains 300A peak forward surge current (IFSM) for an 8.3ms single half-sine wave at 60Hz, per Note 6 and 7 in DS40742. This rating assumes mounting on 8.00mm² copper land areas and applies to uni-directional interpretation; bi-directional operation maintains equivalent energy-handling capability in either polarity.
