Product details
Overview
SMCJ6.5CAQ-13-F from Diodes Incorporated is a bidirectional 1,500W automotive transient voltage suppressor (TVS) diode in SMC package, with 6.5V reverse standoff voltage, 11.2V max clamping voltage at 133.9A peak pulse current, and AEC-Q101 qualification for ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD protection in vehicle power-line interfaces.
For engineers reviewing the SMCJ6.5CAQ-13-F datasheet, SMCJ6.5CAQ-13-F pinout, SMCJ6.5CAQ-13-F application, or SMCJ6.5CAQ-13-F equivalent, this part supports high-reliability surge suppression in 12V automotive systems where fast response (<1 ns), low clamping ratio (1.72), and IATF 16949 traceable manufacturing are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal lines without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior under repeated transients, and its 1,500W peak pulse rating sustains energy absorption per ISO7637-2 Pulse 3b (+100V, 10×1000μs waveform).
The device exhibits 500μA max reverse leakage at VRWM = 6.5V and achieves clamping within 1 ns of transient onset. Thermal design must account for 5.0W steady-state dissipation at TL = +75°C and derating above ambient, with operating junction temperature spanning −55°C to +150°C for under-hood deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - absorbs ISO7637-2 Pulse 1 (−100V) and Pulse 3b (+100V) without failure |
| Reverse Standoff Voltage | 6.5V - sets minimum working voltage before clamping activates in 12V automotive systems |
| Max Clamping Voltage | 11.2V @ 133.9A - limits downstream IC stress to safe levels during 10×1000μs surges |
| Breakdown Voltage | 7.22–7.98V @ 10mA - ensures tight VBR tolerance for predictable turn-on margin |
| Leakage Current | ≤500μA @ 6.5V - minimizes standby power loss in always-on vehicle modules |
| Operating Temperature | −55°C to +150°C - supports placement near engines or in battery management units |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 flammability rating, cathode band omitted due to bidirectional construction, 0.21g weight, and matte tin lead finish compliant with MIL-STD-202 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (Symmetrical) | Transient conduction path | Both terminals behave identically - no polarity dependency enables use on differential buses or ungrounded lines |
| Case / Body | Thermal mass & mechanical anchor | SMC package provides 5.0W steady-state dissipation at TL = +75°C; requires ≥6.9mm pad width per Diodes' layout guide |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of CAN FD, LIN, or sensor bridges without external polarity routing |
| Glass-passivated die | Ensures long-term stability of VBR and leakage under thermal cycling and humidity exposure |
| AEC-Q101 qualification | Validates reliability for automotive powertrain, chassis, and ADAS modules per stress test requirements |
| Lead-free & halogen-free | Meets RoHS 3 and automotive green standards (<900ppm Br, <900ppm Cl, <1000ppm Sb) |
Applications
| Infotainment Power Rail Protection | CAN FD Transceiver Interface |
|---|---|
Use Scenario: Protecting USB-C PD port and display power inputs in head units against load dump and jump-start surges. IC Role / Device Role: Primary clamping element placed between fuse and DC-DC converter input. Use Value: Limits transient voltage to ≤11.2V, preventing latch-up or overvoltage shutdown in PMICs rated for 13.2V absolute max. | Use Scenario: Safeguarding CAN FD physical layer transceivers during battery disconnect events and alternator ripple. IC Role / Device Role: Bidirectional shunt clamp across CANH–CANL differential pair and common-mode lines. Use Value: Maintains signal integrity by clamping common-mode surges without distorting differential timing or adding capacitance (>100pF). |
| Body Control Module (BCM) Inputs | ADAS Camera Power Conditioning |
Use Scenario: Shielding wake-up inputs, door lock actuators, and lighting drivers from ISO7637-2 Pulse 2a (+50V) induced by relay switching. IC Role / Device Role: Localized TVS at connector entry point, upstream of polyfuse and LDO. Use Value: Absorbs 200A peak surge without degradation, preserving 10-year field life in 12V/24V dual-battery architectures. | Use Scenario: Securing 12V input to image sensor SoCs in rear-view and surround-view cameras exposed to engine bay EMI. IC Role / Device Role: First-stage protector before ceramic filter and buck converter. Use Value: Fast 1ns response prevents pixel corruption or frame drop during ignition transients, verified per ISO10605 contact discharge (30kV). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5CA | Lower 600W peak power, SMB package (smaller thermal mass) | Not suitable for ISO7637-2 Pulse 1 (−100V) or sustained surge duty cycles | Select only for space-constrained non-critical 12V sensors with <100A surge exposure |
| 1.5KE6.8CA | Through-hole DO-201 package, same 1500W rating but slower response (~5ns) and higher VF | Requires board real estate and wave-solder process; unsuitable for automated SMT lines | Choose only for legacy designs or repair kits where SMT rework is impractical |
Compared with SMBJ6.5CA and 1.5KE6.8CA, SMCJ6.5CAQ-13-F delivers superior thermal robustness in SMT automotive production, tighter VBR tolerance, and guaranteed AEC-Q101 compliance-making it the only option qualified for new ECUs targeting PPAP release.

FAQ
What does the "AQ" suffix signify in SMCJ6.5CAQ-13-F?
The "AQ" suffix denotes AEC-Q101 qualification and PPAP capability, confirming that the device underwent stress testing per automotive reliability standards-including HTOL, TCT, ESD, and surge endurance-and was manufactured in an IATF 16949-certified facility with full lot traceability and change control.
Is SMCJ6.5CAQ-13-F unidirectional or bidirectional?
It is bidirectional, indicated by the "C" in the part number (SMCJ6.5CAQ-13-F). This allows symmetrical clamping across both polarities, making it suitable for protecting differential buses like CAN, LIN, or RS-485 without polarity-sensitive placement.
What is the maximum clamping voltage and at what current is it specified?
The maximum clamping voltage is 11.2V, measured at a peak pulse current (IPP) of 133.9A using the standardized 10×1000μs waveform defined in REA and ISO7637-2. This value is guaranteed across the full operating temperature range (−55°C to +150°C).
Can SMCJ6.5CAQ-13-F replace SMCJ6.5A-13-F in an existing design?
No-SMCJ6.5A-13-F is unidirectional, while SMCJ6.5CAQ-13-F is bidirectional and AEC-Q101 qualified. Substitution would require verifying circuit polarity, revalidating surge performance per ISO7637-2 Pulse 1/3a, and updating PPAP documentation to reflect the AQ-grade qualification status.
