Product details
Overview
3.0SMCJ64CAQ-13 from Diodes Incorporated is a bi-directional automotive-grade transient voltage suppressor (TVS) diode in SMC package, rated for 3000W peak pulse power, 64V reverse standoff voltage (VRWM), and 103V maximum clamping voltage (VC) at 29.1A peak pulse current. It protects CAN, LIN, and power-line circuits in engine control units and body electronics against ISO7637-2 Pulse 1/2a/3a/3b surges and ISO10605 ESD events.
For engineers reviewing the 3.0SMCJ64CAQ-13 datasheet, 3.0SMCJ64CAQ-13 pinout, 3.0SMCJ64CAQ-13 application, or 3.0SMCJ64CAQ-13 equivalent, this device is selected for AEC-Q101-compliant 12V/24V automotive systems requiring sub-105V clamping under 30A surge, RoHS/Green compliance, and IATF16949-manufactured traceability.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal lines without polarity dependency. Its 64V VRWM ensures compatibility with 48V automotive architectures while maintaining margin above nominal bus voltage.
The device uses silicon avalanche junction technology to achieve fast response (<1 ns) to transients and stable clamping performance over -55°C to +175°C operating range. It meets ISO7637-2 Pulse 3b (+150V) and ISO10605 (±30kV contact/air discharge) requirements without external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains 10×1000μs surge without failure in automotive load-dump scenarios |
| Reverse Standoff Voltage (VRWM) | 64V - blocks normal 48V system operation while triggering only above transient threshold |
| Max Clamping Voltage (VC) | 103V @ 29.1A - limits downstream IC voltage to safe level during ISO7637-2 Pulse 1 (-150V) |
| Breakdown Voltage (VBR) | 71.1–78.6V @ 1mA - defines precise avalanche initiation window for repeatable protection behavior |
| Operating Temperature | -55°C to +175°C - supports under-hood placement in ECUs and battery management modules |
| Leakage Current (IR) | ≤2µA @ 64V - negligible standby power loss in always-on vehicle networks |
| AEC-Q101 Qualified | Yes - validated for automotive reliability including temperature cycling, HTRB, and ESD stress |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 flammability rating; moisture sensitivity level 1 per J-STD-020; weight ≈0.21g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode Band (Marked End) | Anode Terminal (Bi-directional) | Identifies terminal 1; in bi-directional configuration, both terminals function identically as symmetrical avalanche junctions |
| Opposite End | Cathode Terminal (Bi-directional) | Terminal 2; no polarity dependency-device clamps equally for positive or negative transients |
Key Features
| Feature | Design Value |
|---|---|
| 3000W Peak Pulse Power | Enables single-device protection against severe load dump (ISO7637-2 Pulse 5a) up to 300A surge in 12V systems |
| Bi-directional Symmetry | Eliminates need for dual unidirectional devices on differential buses like CAN FD or FlexRay |
| AEC-Q101 Qualification | Validated for automotive life-cycle stress including 1000h HTOL at 175°C and 1000 cycles temperature cycling (-55°C/+175°C) |
| RoHS & Halogen-Free | Meets EU RoHS 3 (2015/863/EU) and Diodes' "Green" definition: Br+Cl <1500ppm, Sb <1000ppm |
| Low Clamping Ratio | VC/VRWM = 1.61 - tighter voltage margin than standard 1.8–2.2 ratio, reducing stress on protected transceivers |
Applications
| Engine Control Unit (ECU) Power Input | CAN FD Transceiver Protection |
|---|---|
Use Scenario: 12V battery feed to microcontroller power supply in gasoline/diesel engine control modules. IC Role / Device Role: Primary overvoltage clamp against ISO7637-2 Pulse 1 (-150V) and load dump transients. Use Value: Limits input rail to ≤103V, preventing damage to 5V LDOs and MCU VDD pins rated for 40V absolute max. |
Use Scenario: Bidirectional protection of CAN_H/CAN_L lines in ADAS domain controllers. IC Role / Device Role: Symmetric clamping of ±30kV ESD (ISO10605) and ±150V Pulse 3b noise. Use Value: Maintains signal integrity below 1.5V common-mode shift during clamping, preserving CAN FD bit timing. |
| Body Control Module (BCM) LIN Bus | 48V Mild Hybrid DC-DC Converter Input |
Use Scenario: LIN physical layer interface in door module or lighting control unit. IC Role / Device Role: Low-capacitance transient suppression on 12V LIN bus with 19.2kbps signaling. Use Value: IR ≤2µA prevents bus pull-down; 103V VC avoids false wake-up of LIN transceivers during ignition pulses. |
Use Scenario: Input stage of bidirectional DC-DC converter linking 12V starter battery and 48V Li-ion stack. IC Role / Device Role: Surge arrestor for ISO7637-2 Pulse 5a (load dump) on 48V rail. Use Value: Withstands 29.1A peak current at 103V clamp, protecting SiC MOSFET gate drivers from overvoltage failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | 2000W PPK, same VRWM/VC, SMB package (smaller footprint, lower thermal mass) | Limited to lower-energy transients; not qualified for AEC-Q101 automotive use | Select when space-constrained and automotive qualification is not required |
| 1.5SMC64CA | 1500W PPK, same VRWM/VC, SMC package but non-automotive grade | Lacks AEC-Q101 validation, PPAP capability, and IATF16949 manufacturing controls | Acceptable for industrial/commercial 48V systems where automotive reliability is not mandated |
Compared with SMBJ64CA and 1.5SMC64CA, the 3.0SMCJ64CAQ-13 delivers 50% higher surge energy handling, full automotive qualification, and guaranteed traceability-making it the sole choice for safety-critical ECU and ADAS power rail protection.

FAQ
What is the clamping voltage of 3.0SMCJ64CAQ-13 at its rated peak pulse current?
The maximum clamping voltage (VC) is 103V measured at 29.1A peak pulse current using the 10×1000μs waveform per Figure 4 in DS40742 Rev. 12–2. This value is guaranteed across -55°C to +175°C operating temperature and reflects worst-case device behavior under standardized surge conditions.
Is 3.0SMCJ64CAQ-13 suitable for protecting CAN FD physical layer interfaces?
Yes-it is bi-directional, has low leakage (≤2µA), and clamps within 103V, preserving the ±1V common-mode tolerance of ISO11898-2 compliant transceivers. Its 1.61 clamping ratio and sub-1ns response ensure signal integrity during ISO10605 ±30kV ESD events on high-speed CAN FD buses.
Does this part require derating at elevated ambient temperatures?
Yes-peak pulse power must be derated linearly above +25°C per Figure 1: at +125°C, maximum PPK is reduced to 50% (1500W). Derating applies to both power and surge current; full 3000W rating is only valid at TA = +25°C with specified PCB land pattern (8.00mm²).
How is AEC-Q101 qualification verified for this TVS diode?
Diodes Incorporated validates 3.0SMCJ64CAQ-13 per AEC-Q101-004 (TVS-specific stress test plan), including HTSL, TCT, HTRB, and ESD testing. Full qualification reports, PPAP documentation, and IATF16949 facility certification are available upon request for OEM design-in.
