Product details
Overview
SMCJ14CAQ-13-F from Diodes Incorporated is a bidirectional automotive-grade transient voltage suppressor (TVS) diode in SMC package, rated for 14 V reverse standoff voltage, 23.2 V max clamping voltage at 64.7 A peak pulse current, and 3000 W peak pulse power (10/1000 µs). It provides ISO 7637-2 (pulses 1, 2a, 2b, 3) and ISO 10605 ESD protection for powerline inputs in body control modules and ADAS ECUs.
For engineers reviewing the SMCJ14CAQ-13-F datasheet, SMCJ14CAQ-13-F pinout, SMCJ14CAQ-13-F application, or SMCJ14CAQ-13-F equivalent, key selection criteria include AEC-Q101 qualification, bidirectional clamping behavior, SMC package thermal robustness, and verified compliance with automotive surge and ESD immunity standards.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal bias (≤14 V), it exhibits ≤5 µA leakage; when exposed to transients exceeding its breakdown range (15.6–17.2 V), it avalanches rapidly to clamp the line at ≤23.2 V. Its bidirectional symmetry enables protection of AC-coupled or floating signal/power rails without polarity constraints.
The device is optimized for high-energy automotive load dump and inductive switching events - delivering 3000 W peak pulse power handling in the SMC package, with thermal design supporting sustained operation in under-hood environments up to 175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 14 V - maximum continuous DC or RMS voltage the device blocks without significant leakage. |
| Breakdown Voltage (VBR) | 15.6–17.2 V @ IT = 1 mA - guaranteed avalanche initiation window for predictable clamping onset. |
| Max Clamping Voltage (VC) | 23.2 V @ Ipp = 64.7 A (10/1000 µs) - peak line voltage seen by protected IC during worst-case surge. |
| Peak Pulse Power (PPPM) | 3000 W - energy-handling capacity sufficient for ISO 7637-2 Pulse 5a (load dump) events. |
| Leakage Current (IR) | ≤5 µA @ VRWM - ensures negligible standby power loss and no interference with low-power sensor circuits. |
| AEC-Q101 Qualification | Qualified - validated for automotive reliability including temperature cycling, HTRB, and ESD stress per AEC standard. |
| Package | SMC (DO-214AB) - thermally efficient surface-mount outline with 6.60–7.11 mm body width and 2.75–3.18 mm height. |
Pinout & Package
SMCJ14CAQ-13-F uses the SMC (DO-214AB) package: a 2-terminal surface-mount device with cathode band marking on one end. The terminals are non-polarized for bidirectional operation; either terminal may serve as anode or cathode depending on transient polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (bidirectional) | Surge current path | Both terminals conduct equally during positive or negative transients - no fixed anode/cathode assignment required in layout. |
| Cathode Band Marking | Polarity indicator | Visible band identifies terminal used for unidirectional variants; irrelevant for bidirectional SMCJ14CAQ-13-F but retained for package compatibility. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of differential lines, CAN bus stubs, or floating power rails without polarity concerns. |
| 3000 W peak pulse rating | Meets ISO 7637-2 Pulse 5a (load dump) requirements up to 40 V/100 ms without failure. |
| AEC-Q101 qualification | Validated for automotive under-hood use including 1000-cycle temperature cycling and 1000-hour HTRB at 175 °C. |
| ISO 10605 & ISO 7637-2 compliance | Guaranteed performance against ±25 kV contact / ±30 kV air ESD and all defined automotive surge pulses (1, 2a, 2b, 3). |
Applications
| Body Control Module (BCM) | ADAS Camera ECU |
|---|---|
Use Scenario: Protects 12 V power input of BCM microcontroller and LIN transceivers from alternator load dump and motor-switching spikes. IC Role / Device Role: Primary shunt clamp on main VBAT rail, placed upstream of DC-DC converter input. Use Value: Limits transient overvoltage to ≤23.2 V, preventing latch-up or gate oxide damage in downstream 3.3 V/5 V logic. |
Use Scenario: Shields FPD-Link III serializer power and data lines in rear-view camera modules from cable-induced surges. IC Role / Device Role: Bidirectional clamping element across power and differential video pairs to suppress common-mode and differential transients. Use Value: Maintains signal integrity during hot-plug events and meets OEM EMC test limits for ISO 10605 ±25 kV ESD. |
| HVAC Blower Motor Driver | Infotainment Head Unit Power Input |
Use Scenario: Guards gate driver ICs and current-sense amplifiers in 12 V brushed DC motor control circuits against inductive kickback. IC Role / Device Role: Low-inductance placement between MOSFET bridge supply and chassis ground to divert flyback energy. Use Value: Withstands repetitive 100 A surge currents (per ISO 7637-2 Pulse 2b) without parameter shift or thermal runaway. |
Use Scenario: Secures 12 V input stage of head unit DC-DC converters against battery disconnection transients and jump-start surges. IC Role / Device Role: First-line defense before input filter capacitor, reducing stress on upstream fuse and EMI choke. Use Value: Enables compact 3000 W-rated protection in constrained front-panel PCB space while meeting GMW3172 Class III requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ14CAHR6G | Same electrical specs; different tape-and-reel packaging (13-inch reel vs. 7-inch) and traceability labeling. | No functional difference; selected when specific PPAP documentation or lot traceability format is mandated. | Choose HR6G for Tier-1 automotive programs requiring full MRP-compatible lot serialization. |
| TPSMC14CA | Higher clamping voltage (25.5 V @ 60 A); lower peak power (2000 W); same SMC footprint. | Suitable for less severe surge environments (e.g., interior modules), not recommended for engine bay or load-dump-critical nodes. | Select only if system-level testing confirms 25.5 V clamping margin is acceptable for protected IC VDS(max) and VGS(max). |
Compared with SMCJ14CAQ-13-F, SMCJ14CAHR6G offers identical protection performance with enhanced logistics traceability, while TPSMC14CA trades 1000 W pulse capability and 2.3 V tighter clamping for cost-sensitive interior applications where ISO 7637-2 Pulse 5a is not required.

FAQ
Is SMCJ14CAQ-13-F unidirectional or bidirectional?
SMCJ14CAQ-13-F is a bidirectional TVS diode, indicated by the "CA" suffix in its part number. It provides symmetrical clamping for both positive and negative transients, making it suitable for AC-coupled lines, differential buses, or floating power domains without polarity constraints.
What is the maximum operating temperature for SMCJ14CAQ-13-F?
The device is rated for junction temperatures from –65 °C to +175 °C and qualified per AEC-Q101 thermal cycling and HTRB tests at 175 °C. Its SMC package supports reliable operation in under-hood environments when mounted on ≥1 sq-in copper area with 2 oz copper weight.
Does SMCJ14CAQ-13-F meet OEM-specific surge requirements like GMW3172 or Ford ES-XW7T-1A278-AC?
Yes - its ISO 7637-2 Pulse 1, 2a, 2b, and 3 compliance, combined with 3000 W peak power rating, satisfies the transient immunity requirements of GMW3172 Class III and Ford ES-XW7T-1A278-AC for powerline protection in Class C (body electronics) and Class D (infotainment) modules.
Can SMCJ14CAQ-13-F replace SMAJ14CAQ in an existing design?
No - SMAJ14CAQ is in SMA package with 400 W rating and higher clamping impedance. Substituting SMCJ14CAQ-13-F requires verifying PCB pad layout (SMC vs. SMA), thermal relief, and whether the higher 3000 W rating introduces unintended interaction with upstream fusing or downstream TVS staging in multi-stage protection schemes.
