Product details
Overview
SMCJ16CAQ-13-F from Diodes Incorporated is a bidirectional 1,500W automotive transient voltage suppressor (TVS) diode in SMC package, with 16V reverse standoff voltage (VRWM), 26.0V max clamping voltage (VC) at 57.7A peak pulse current (IPP), and AEC-Q101 qualification for ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD protection in vehicle power line and signal interface circuits.
For engineers reviewing the SMCJ16CAQ-13-F datasheet, SMCJ16CAQ-13-F pinout, SMCJ16CAQ-13-F application, or SMCJ16CAQ-13-F equivalent, this part supports high-reliability surge suppression in 12V/24V automotive subsystems where fast response (<1 ns), low clamping ratio (1.625), and IATF 16949-manufactured consistency are critical selection criteria.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance for positive and negative transients-enabling single-device protection of AC-coupled or floating signal lines without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics over temperature (-55°C to +150°C operating range) and long-term reliability under repeated surge stress.
The device uses a 10/1000μs double-exponential pulse waveform per REA standards, with 1,500W peak pulse power derated linearly above +25°C ambient and fully compliant with ISO7637-2 Pulse 1 (-100V), Pulse 2a (+50V), Pulse 3a (-150V), and Pulse 3b (+100V) test profiles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains 10/1000μs surges up to 57.7A without failure in automotive load-dump or inductive switching events |
| Reverse Standoff Voltage | 16.0V - defines maximum continuous DC or RMS operating voltage before significant leakage begins |
| Max Clamping Voltage | 26.0V @ IPP = 57.7A - limits transient voltage seen by downstream ICs to safe levels during ISO7637-2 Pulse 1/3a |
| Breakdown Voltage | 17.8–19.7V @ IT = 1.0mA - ensures precise, repeatable avalanche initiation with tight tolerance (±5.6%) |
| Leakage Current | ≤5.0µA @ VRWM = 16V - minimizes standby power loss and avoids false triggering in low-power sensor interfaces |
| Response Time | <1.0ns - reacts faster than most microcontrollers and CAN transceivers, preventing latch-up or gate oxide damage |
| Operating Temperature | -55°C to +150°C - supports under-hood placement and compatibility with AEC-Q101 thermal cycling requirements |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 flammability rating, cathode band omitted (bidirectional configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Identical avalanche behavior in both directions; no polarity dependency-simplifies PCB layout for differential or floating lines |
| Case / Body | Thermal mass & mechanical anchor | 0.21g weight and 6.60–7.11mm width enable robust thermal dissipation to copper pour while meeting automotive vibration specs |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals (e.g., LIN, CAN FD stubs) without external polarity management circuitry |
| AEC-Q101 qualification | Validated for automotive use including HTOL, TC, UHAST, and ESD testing-reduces qualification burden for Tier 1 suppliers |
| Glass-passivated die | Eliminates moisture-induced parameter drift and improves long-term stability in humid engine bay environments |
| Lead-free & halogen-free | Meets RoHS 3 (2015/863/EU) and "Green" definition (<900ppm Br, <900ppm Cl, <1000ppm Sb)-supports global vehicle recycling mandates |
Applications
| Infotainment Display Power Rail | Body Control Module (BCM) LIN Bus |
|---|---|
Use Scenario: Protecting 12V supply input to TFT display modules against battery load dump and alternator ripple. IC Role / Device Role: Primary overvoltage clamp on main VCC rail, placed upstream of DC-DC converters and LDOs. Use Value: Limits transient voltage to ≤26.0V, preventing damage to display driver ICs rated for 30V absolute maximum. | Use Scenario: Shielding LIN transceiver PHY pins from ESD events during connector mating/unmating in door modules. IC Role / Device Role: Bidirectional ESD clamp between LIN_H and LIN_L lines, referenced to local ground. Use Value: Withstands ±30kV contact discharge per ISO10605 while adding <1pF parasitic capacitance-no data rate degradation. |
| ADAS Camera Power Input | Electric Power Steering (EPS) Sensor Interface |
Use Scenario: Safeguarding 12V input to image sensor SoCs exposed to ignition noise and relay switching spikes. IC Role / Device Role: First-line transient suppressor before input filter capacitors and protection FETs. Use Value: 1,500W rating handles repetitive 50V pulses (ISO7637-2 Pulse 2a) without parametric shift over 10-year vehicle life. | Use Scenario: Protecting analog outputs of torque sensors in EPS control units from inductive kickback during motor commutation. IC Role / Device Role: Low-leakage (≤5µA) bidirectional clamp on ratiometric analog voltage output lines. Use Value: Maintains signal integrity with <0.1% full-scale error contribution at 16V bias-critical for ASIL-B functional safety compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC16C.TCT | Same 16V VRWM and bidirectional configuration but lower 1,000W PPK rating and 28.0V VC @ 35.7A IPP | Limited to lower-energy transients (e.g., ISO7637-2 Pulse 2a only); not validated for Pulse 1 or 3a | Select when cost sensitivity outweighs need for full ISO7637-2 coverage and board space allows larger footprint |
| TPSMD16C | 16V VRWM, 26.0V VC, but unidirectional-requires dual-device implementation for AC protection | Increases BOM count and PCB area; introduces asymmetry in clamping thresholds for positive/negative transients | Choose only if existing design already uses unidirectional TVS layout and system-level analysis confirms polarity-specific threat model |
Compared with SAC16C.TCT and TPSMD16C, SMCJ16CAQ-13-F delivers higher surge margin (1500W vs. 1000W), guaranteed bidirectional symmetry, and full AEC-Q101/ISO7637-2 Pulse 1–3b validation-making it the preferred choice for new automotive designs requiring single-device, drop-in-ready surge resilience.

FAQ
What does the 'C' suffix in SMCJ16CAQ-13-F signify?
The 'C' denotes bidirectional configuration-meaning the device provides symmetrical clamping for both positive and negative voltage transients without polarity dependence. This eliminates the need for separate anode/cathode orientation during placement and enables protection of AC-coupled or floating signal paths such as LIN or CAN stubs.
Is SMCJ16CAQ-13-F compatible with lead-free reflow processes?
Yes-it features matte tin lead-free plating, qualified per J-STD-020 Level 1 moisture sensitivity, and is fully compatible with standard Pb-free reflow profiles (peak temperature up to 260°C). The SMC package's thermal mass ensures reliable solder joint formation without die cracking or delamination.
How does its clamping voltage compare to unidirectional variants at the same VRWM?
At 16V VRWM, the bidirectional SMCJ16CAQ-13-F has a max clamping voltage of 26.0V @ 57.7A, identical to the unidirectional SMCJ16AQ-13-F. This parity results from matched die construction-ensuring no performance trade-off when selecting bidirectional functionality for simplified design.
Can this TVS be used in non-automotive applications like industrial PLC I/O protection?
Yes-its 1500W rating, -55°C to +150°C operation, and low leakage make it suitable for industrial 24V DC control systems. However, AEC-Q101 qualification is not required outside automotive; for cost-sensitive industrial use, non-automotive equivalents (e.g., SMAJ16CA) may offer comparable electrical specs without automotive process controls.
