Product details
Overview
3.0SMCJ16CAQ-13 from Diodes Incorporated is a bi-directional 3000W surface-mount transient voltage suppressor (TVS) designed for automotive power line protection. It features a 16V reverse standoff voltage (VRWM), 26.0V max clamping voltage (VC) at 115.4A peak pulse current (IPP), and AEC-Q101 qualification for under-hood applications such as engine control units and body electronics.
For engineers reviewing the 3.0SMCJ16CAQ-13 datasheet, 3.0SMCJ16CAQ-13 pinout, 3.0SMCJ16CAQ-13 application, or 3.0SMCJ16CAQ-13 equivalent, this device is selected for ISO7637-2 Pulse 1/2a/3a/3b surge suppression and ISO10605 ESD protection in 12V/24V automotive systems where bidirectional clamping, low leakage (<2 µA @ VRWM), and IATF16949-manufactured consistency are required.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling robust protection against negative and positive transients without polarity dependency. Its 10×1000µs waveform response ensures compliance with ISO7637-2 Pulse 3a (−220V) and Pulse 3b (+150V), while its 8.3ms half-sine surge rating supports IFSM = 300A non-repetitive forward surge capability.
The device uses silicon avalanche junction technology to achieve precise breakdown (17.8–19.7V) and tight clamping (26.0V max), with thermal stability across −55°C to +175°C operating range. Its SMC package provides low thermal resistance and meets J-STD-020 Level 1 moisture sensitivity for reflow compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains high-energy transients per ISO7637-2 without failure |
| Reverse Standoff Voltage (VRWM) | 16.0V - defines maximum continuous DC or RMS voltage before clamping initiates |
| Max Clamping Voltage (VC) | 26.0V @ 115.4A - limits downstream circuit voltage during 10×1000µs surge |
| Breakdown Voltage (VBR) | 17.8–19.7V @ 1.0mA - ensures reliable avalanche conduction onset within spec |
| Peak Pulse Current (IPP) | 115.4A - quantifies maximum transient current the device can safely shunt |
| Leakage Current (IR) | <2 µA @ 16V - minimizes standby power loss in always-on automotive modules |
| Operating Temperature | −55°C to +175°C - supports placement near engines or in battery management systems |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic with UL 94V-0 flammability rating; 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; device functions identically in either direction due to symmetrical structure |
| Opposite Terminal | Cathode for bi-directional operation | Paired with marked end to form bidirectional clamping path across power rail and ground |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, HTRB, and ESD stress per JEDEC standards |
| IATF16949 manufacturing | Ensures consistent lot-to-lot performance and full PPAP documentation support |
| Bi-directional clamping | Protects against both positive and negative transients without external polarity management |
| Lead-free & halogen-free | RoHS 3 compliant with <900ppm Br/Cl and <1000ppm Sb - meets global automotive environmental mandates |
| Low clamping ratio (VC/VRWM) | 1.625 - enables tighter voltage margin between operating rail and protection threshold |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Infotainment Display Supply |
|---|---|
Use Scenario: 12V battery line feeding microcontroller and CAN transceiver in engine bay. IC Role / Device Role / Timing Role: Bidirectional TVS placed upstream of LDO regulator to clamp ISO7637-2 Pulse 1 (−150V) and Pulse 2a (+112V). Use Value: Prevents latch-up or gate oxide damage in 3.3V/5V logic by limiting rail voltage to ≤26V during surge events. |
Use Scenario: 24V supply line to LCD backlight driver and touch controller in center console. IC Role / Device Role / Timing Role: Primary surge suppressor on main power input, coordinated with local ceramic decoupling. Use Value: Maintains display functionality during load dump (Pulse 3b +150V) without requiring oversized input capacitors. |
| Body Control Module (BCM) LIN Bus Interface | ADAS Camera Module Power Rail |
Use Scenario: Protection of LIN transceiver VCC pin against ESD and board-level coupling. IC Role / Device Role / Timing Role: Secondary TVS on low-voltage domain, complementing primary front-end protection. Use Value: Limits transient-induced bit errors by clamping fast-rising ESD pulses (ISO10605, 30kV contact) to sub-30V. |
Use Scenario: 12V input to image sensor and serializer IC in rear-view camera housing. IC Role / Device Role / Timing Role: First-line defense against cable-borne surges induced by nearby motor actuation. Use Value: Enables uninterrupted video streaming during Pulse 3a (−220V) by maintaining power rail integrity below sensor overvoltage threshold. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | 2000W PPK, same VRWM/VC but lower IPP (83.3A) and higher VC (26.5V) | Limited to lower-energy transients; unsuitable for full ISO7637-2 Pulse 1 compliance | Select when space constraints require SMB package and surge energy is ≤2000W |
| SMCJ16CA | Same 3000W rating and SMC package, but lacks AEC-Q101 qualification and PPAP support | Not approved for production automotive programs requiring change control and traceability | Use only in non-automotive industrial or consumer designs where qualification is not mandated |
Compared with SMBJ16CA and SMCJ16CA, the 3.0SMCJ16CAQ-13 uniquely delivers AEC-Q101 validation, IATF16949 traceability, and guaranteed 3000W clamping performance-making it the sole choice for Tier 1 automotive power rail protection requiring PPAP documentation and full ISO7637-2 coverage.

FAQ
What does the "C" suffix in 3.0SMCJ16CAQ-13 indicate?
The "C" denotes bi-directional configuration, meaning the device clamps transients of either polarity symmetrically across its terminals. Unlike uni-directional variants (e.g., 3.0SMCJ16AQ-13), it has no inherent anode/cathode distinction and functions identically regardless of voltage polarity applied-critical for protecting AC-coupled or floating automotive signal lines.
How does 3.0SMCJ16CAQ-13 differ from standard 3.0SMCJ16CA?
The "Q" suffix indicates AEC-Q101 qualification, PPAP capability, and manufacture in IATF16949-certified facilities-requirements absent in the commercial-grade 3.0SMCJ16CA. Electrical specs are identical, but the Q-grade part includes full automotive change control, lot traceability, and extended reliability testing per JEDEC A113.
Can this TVS replace a 16V Zener diode in surge protection?
No-Zener diodes lack the 3000W peak pulse power rating and controlled clamping dynamics of this TVS. While both regulate voltage, the 3.0SMCJ16CAQ-13 is optimized for transient energy absorption (10×1000µs), whereas Zeners are intended for steady-state regulation and fail catastrophically under surge conditions.
What PCB layout considerations apply for optimal clamping performance?
Minimize trace inductance between the TVS and protected node using short, wide copper paths; place it directly across the power rail and ground plane. Use ≥8.00 mm² pad land areas per terminal to maintain thermal derating integrity, and avoid routing sensitive signals near the TVS body to prevent coupling during clamping events.
