Product details
Overview
SMCJ17CAQ-13-F from Diodes Incorporated is a bidirectional 1,500W automotive transient voltage suppressor (TVS) diode in SMC package, with 17V reverse standoff voltage (VRWM), 27.6V max clamping voltage at 53.3A peak pulse current, and AEC-Q101 qualification for under-hood power line protection against ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD events.
For engineers reviewing the SMCJ17CAQ-13-F datasheet, SMCJ17CAQ-13-F pinout, SMCJ17CAQ-13-F application, or SMCJ17CAQ-13-F equivalent, this part is selected for robust surge immunity in 12V/24V automotive subsystems where fast clamping (<1 ns), low leakage (<5 µA @ 17V), and IATF 16949-manufactured reliability are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering 1,500W peak pulse power per the 10/1000 µs waveform, with breakdown voltage VBR of 18.9–20.9V at 1mA test current and thermal operation from –55°C to +150°C junction temperature.
Its glass-passivated die construction ensures stable clamping performance under repeated surge stress, while the SMC package supports 200A non-repetitive forward surge current (8.3 ms half-sine) and maintains <5 µA reverse leakage at VRWM - critical for low-power always-on automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single 10/1000 µs transients up to ISO7637-2 Pulse 3b (+100V) without failure |
| Reverse Standoff Voltage | 17V - blocks normal 12V/24V system operating voltages while remaining fully inactive |
| Max Clamping Voltage | 27.6V @ 53.3A - limits downstream IC voltage to safe level during worst-case surge |
| Breakdown Voltage | 18.9–20.9V @ 1mA - precise, tightly distributed VBR ensures consistent turn-on across production lots |
| Leakage Current | <5 µA @ 17V - avoids battery drain in always-on vehicle networks (e.g., CAN/LIN standby) |
| Operating Temperature | –55°C to +150°C - qualified for engine bay, transmission control, and ADAS sensor environments |
| AEC-Q101 Qualified | Yes - validated for automotive use with PPAP capability and IATF 16949 manufacturing |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 flammability rating, cathode band omitted (bidirectional device), 0.21g weight, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Surge conduction path | Identical terminals handle bidirectional transients - no polarity dependency in PCB layout |
| Case / Body | Thermal mass & mechanical anchor | Provides primary heat dissipation path to PCB copper; requires ≥25 mm² 2-oz copper pad for PM(AV) = 5W derating |
Key Features
| Feature | Design Value |
|---|---|
| 1,500W peak pulse rating | Enables single-device protection against ISO7637-2 Pulse 1 (–100V) and Pulse 3a (–150V) without cascaded clamping |
| Glass-passivated die | Eliminates passivation layer degradation under humidity/temperature cycling - critical for 15-year automotive life |
| Bidirectional architecture | Protects AC-coupled lines (e.g., LIN bus, analog sensor inputs) without external polarity management |
| Lead-free, halogen-free, RoHS 3 compliant | Meets EU automotive recycling mandates and solder compatibility requirements for Pb-free reflow (J-STD-020 Level 1) |
Applications
| Body Control Module (BCM) | Infotainment Power Input |
|---|---|
Use Scenario: Protects 12V supply rail feeding microcontroller, CAN transceiver, and relay drivers from load dump and alternator ripple. IC Role / Device Role: Primary overvoltage clamp on main power input, placed upstream of DC-DC converter. Use Value: Clamps surges to ≤27.6V, preventing latch-up or burnout in 3.3V/5V logic supplies downstream. |
Use Scenario: Shields USB-C PD controller and display power rails from ignition transients and ESD during hot-plug events. IC Role / Device Role: Secondary surge suppression stage after front-end fuse, before LDO regulators. Use Value: Limits ESD energy (30kV contact) to <100 mJ, preserving USB PHY integrity without signal distortion. |
| ADAS Camera Module | Electric Power Steering (EPS) |
Use Scenario: Guards MIPI CSI-2 interface and image sensor bias supply against cable-borne transients in rear-view camera harnesses. IC Role / Device Role: Localized TVS at connector entry point, co-located with common-mode choke. Use Value: Maintains <0.5 pF capacitance (typ.) to avoid degrading 1.5 Gbps video signal integrity. |
Use Scenario: Safeguards motor driver gate drive and MCU power rails from inductive kickback during torque assist switching. IC Role / Device Role: High-energy clamping element on 24V motor supply, rated for 200A surge current. Use Value: Survives >10,000 cycles of ISO7637-2 Pulse 2a (+50V) without parameter shift or leakage increase. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC17-2/TR13 | Same VRWM (17V), lower PPK (600W), higher VC (30.5V @ 30A), SOD-123FL package | Limited to low-energy CAN/LIN nodes; insufficient for load dump or Pulse 1 compliance | Select only for space-constrained, low-risk signal-line protection - not for power rail use |
| TPSMA17CA | Same VRWM (17V), identical PPK (1500W), tighter VBR (18.9–20.0V), SMA package (lower thermal mass) | Lower steady-state power handling (PM(AV) = 1W vs. 5W); unsuitable for sustained surge duty cycles | Prefer for cost-sensitive non-automotive designs; avoid in IATF 16949 or PPAP-driven programs |
Compared with SAC17-2/TR13 and TPSMA17CA, SMCJ17CAQ-13-F uniquely combines AEC-Q101 qualification, 5W steady-state dissipation, and SMC thermal robustness - making it the only choice for high-reliability 12V/24V power rail protection in production automotive ECUs.

FAQ
What is the clamping voltage of SMCJ17CAQ-13-F at 53.3A?
The maximum clamping voltage (VC) is 27.6V at 53.3A peak pulse current under the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range (–55°C to +150°C) and ensures downstream components see no more than 27.6V during surge events.
Is SMCJ17CAQ-13-F unidirectional or bidirectional?
It is bidirectional, indicated by the "C" suffix in the part number. Unlike unidirectional variants, it has no cathode band marking and provides symmetrical clamping for both positive and negative transients - essential for protecting AC-coupled or floating signal lines.
Does this TVS require a heatsink for 5W continuous dissipation?
No external heatsink is required. The 5W steady-state power rating (PM(AV)) is achievable with a minimum 25 mm² copper pad (2-oz) on the PCB acting as the thermal interface. Derating begins above +75°C lead temperature per Figure 6 in DS40741.
How does SMCJ17CAQ-13-F meet ISO10605 ESD requirements?
It passes 30kV air and contact discharge per ISO10605 (C = 150 pF, R = 330 Ω) due to sub-nanosecond response time and low dynamic impedance. Its bidirectional structure ensures equal protection regardless of ESD polarity, verified across production lots per AEC-Q101 stress testing.
