Product details
Overview
3.0SMCJ17CAQ-13 from Diodes Incorporated is a bi-directional automotive-grade transient voltage suppressor (TVS) diode in SMC package, rated for 3000W peak pulse power, 17V reverse standoff voltage (VRWM), and clamping voltage of 27.6V at 108.7A peak pulse current. It protects CAN, LIN, and body control modules against ISO7637-2 Pulse 1/2a/3a/3b transients and ISO10605 ESD events up to ±30kV.
For engineers reviewing the 3.0SMCJ17CAQ-13 datasheet, 3.0SMCJ17CAQ-13 pinout, 3.0SMCJ17CAQ-13 application, or 3.0SMCJ17CAQ-13 equivalent, this AEC-Q101 qualified TVS offers verified clamping performance, IATF16949-manufactured traceability, and RoHS/halogen-free compliance - critical for automotive power rail and signal line surge protection design.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling robust protection of differential buses like CAN FD without polarity sensitivity. Its 17V VRWM ensures compatibility with 12V automotive systems while maintaining low leakage (<2µA) and fast response to 10/1000µs transients.
The device delivers 3000W peak pulse power per ISO7637-2 Pulse 3b (150V, 10×1000µs), with clamping voltage tightly controlled at 27.6V - limiting downstream IC stress to safe levels during load dump or inductive switching events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains ISO7637-2 Pulse 3b (150V, 10×1000µs) without failure |
| Reverse Standoff Voltage (VRWM) | 17V - blocks normal 12V system operation while triggering above transient thresholds |
| Clamping Voltage (VC) | 27.6V @ 108.7A - limits voltage seen by protected MCU or transceiver during surge |
| Breakdown Voltage (VBR) | 18.9–20.9V @ 1mA - ensures reliable turn-on before damage to downstream components |
| Peak Pulse Current (IPP) | 108.7A - handles high-energy transients from alternator load dump or motor commutation |
| Operating Temperature | −55°C to +175°C - supports under-hood placement in engine control units and ADAS sensors |
| AEC-Q101 Qualified | Yes - validated for automotive reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic UL 94V-0 housing; weight ≈ 0.21g; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode Band (Marked End) | Anode for bi-directional operation | Identifies terminal orientation; bi-directional symmetry means either end serves as anode/cathode depending on transient polarity |
| Opposite Terminal | Cathode for bi-directional operation | Completes symmetrical conduction path - no fixed polarity required in layout |
Key Features
| Feature | Design Value |
|---|---|
| 3000W Peak Pulse Power | Enables single-device protection against worst-case ISO7637-2 Pulse 3b (150V, 10×1000µs) without derating |
| Bi-directional Clamping | Eliminates polarity concerns on differential buses (e.g., CAN_H/CAN_L) and AC-coupled signals |
| AEC-Q101 Qualification | Validated for automotive use including HTOL, temperature cycling, and ESD per JESD22-A114 |
| RoHS & Halogen-Free | Meets EU RoHS 3 (2015/863/EU) and Diodes' "Green" standard (<900ppm Br/Cl, <1000ppm Sb) |
| Low Clamping Ratio | VC/VRWM = 1.62 - tight voltage control minimizes overvoltage stress on protected ASICs |
Applications
| Automotive CAN Bus Protection | Body Control Module (BCM) Power Input |
|---|---|
|

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 |
|---|---|---|---|
| SMAJ17CA | Lower peak power (400W), SMA package, same VRWM and VC | Not suitable for ISO7637-2 Pulse 3b; limited to lower-energy ESD and minor load dump | Select only for cost-sensitive non-critical 12V signal lines where 3000W capability is unnecessary |
| SMCJ17CA | Same specs but non-automotive grade; lacks AEC-Q101 qualification and PPAP documentation | Acceptable for industrial or consumer use; not approved for OEM automotive BOMs | Choose only if automotive qualification and IATF16949 traceability are not required |
Compared with SMAJ17CA and SMCJ17CA, the 3.0SMCJ17CAQ-13 uniquely combines 3000W surge capacity, AEC-Q101 certification, and full PPAP support - making it the only option qualified for safety-critical automotive power and data lines requiring ISO7637-2 compliance.

FAQ
What does the 'C' suffix in 3.0SMCJ17CAQ-13 indicate?
The 'C' denotes bi-directional configuration, meaning the device clamps transients of either polarity symmetrically - essential for protecting differential buses like CAN or AC-coupled signals without polarity constraints. This differs from uni-directional variants (e.g., 3.0SMCJ17AQ-13) that require correct anode/cathode orientation.
Is 3.0SMCJ17CAQ-13 compatible with lead-free reflow soldering processes?
Yes - it features matte tin lead-free plating compliant with JEDEC J-STD-020 moisture sensitivity Level 1 and withstands standard Pb-free reflow profiles (peak 260°C). The SMC package is rated for solderability per MIL-STD-202, Method 208, and has UL 94V-0 flammability rating.
How does its clamping voltage compare to competing 17V TVS diodes?
At 27.6V clamping voltage (VC) under 108.7A IPP, it achieves a VC/VRWM ratio of 1.62 - tighter than typical industry benchmarks (often >1.7). This lower ratio reduces overvoltage stress on protected transceivers and MCUs during ISO7637-2 Pulse 3b events.
Can this TVS be used in parallel to increase surge handling capacity?
No - paralleling TVS diodes is not recommended due to mismatch in breakdown voltage (VBR tolerance ±5%) causing uneven current sharing and potential thermal runaway. For higher energy requirements, select a higher-power variant (e.g., 5.0SMCJ17CAQ) or add staged protection with MOVs.
