Product details
Overview
SMBJ16AQ-13-F from Diodes Incorporated is a unidirectional 600W automotive-grade transient voltage suppressor (TVS) diode with 16V reverse standoff voltage, 26.0V max clamping voltage at 23.1A peak pulse current, and AEC-Q101 qualification. It protects CAN, LIN, and sensor interfaces in 12V automotive power domains against ISO7637-2 Pulse 1 (−150V), Pulse 2a (+112V), and ISO10605 ESD (±30kV).
For engineers reviewing the SMBJ16AQ-13-F datasheet, SMBJ16AQ-13-F pinout, SMBJ16AQ-13-F application, or SMBJ16AQ-13-F equivalent, this device is selected for robust surge immunity in engine control units, body electronics modules, and ADAS camera power rails where clamping voltage margin, low leakage (<0.5µA @ 16V), and IATF 16949 traceability are critical.
Technical Context
This unidirectional TVS operates as a shunt-clamping device triggered by reverse-biased avalanche breakdown above VRWM = 16.0V. Its 26.0V clamping voltage (VC) at IPP = 23.1A ensures downstream ICs see sub-28V transients during ISO7637-2 Pulse 3b (+150V) events.
Designed for surface-mount integration in SMB package, it delivers 600W peak pulse power (10/1000µs waveform) with thermal derating to 4.8W/°C above +25°C ambient and supports −55°C to +175°C junction operation - matching under-hood automotive temperature requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 10/1000µs surges up to 23.1A without failure |
| Reverse Standoff Voltage | 16.0V - blocks normal 12V system transients up to +16V before clamping |
| Max Clamping Voltage | 26.0V @ 23.1A - limits voltage seen by protected MCU I/O or transceiver to ≤26V |
| Breakdown Voltage | 17.8–19.7V @ 1.0mA - ensures reliable turn-on with margin above VRWM |
| Leakage Current | <0.5µA @ 16V - avoids battery drain in always-on vehicle networks |
| Operating Temp Range | −55°C to +175°C - qualified for under-hood ECU and transmission control environments |
| AEC-Q101 Qualified | Yes - validated for automotive reliability including HTOL, TC, UHAST, and ESD testing |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic (UL 94V-0), 0.1g weight, matte tin-plated terminals. Cathode band denotes polarity on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to chassis or signal ground; completes clamping path during negative transients |
| Cathode | Protected line input | Connected to 12V rail or signal line; avalanche conduction occurs when cathode-to-anode voltage exceeds 16V |
Key Features
| Feature | Design Value |
|---|---|
| 600W Peak Pulse Power | Enables protection against high-energy ISO7637-2 Pulse 1 (−150V) without degradation |

| AEC-Q101 Qualification | Confirms reliability for automotive safety-critical systems with PPAP documentation support |
| RoHS & Halogen-Free | Meets EU Directive 2015/863/EU with Br+Cl <1500ppm and Sb <1000ppm - compliant for global OEM supply chains |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|
Use Scenario: Protects 12V power input and sensor analog lines from load dump and alternator ripple. IC Role / Device Role / Timing Role: Shunt TVS placed between VBAT and GND upstream of DC/DC converters and microcontroller LDOs. Use Value: Limits transient voltage to ≤26V, preventing latch-up or overvoltage damage to 3.3V/5V domain ICs during ISO7637-2 Pulse 1 (−150V). | Use Scenario: Shields LIN bus transceivers and door actuator drivers from ESD and switching noise. IC Role / Device Role / Timing Role: Unidirectional clamp on LIN data line (cathode to LIN, anode to GND) and VCC rail. Use Value: Clamps contact discharge ESD (±30kV per ISO10605) to <26V within nanoseconds, preserving signal integrity and transceiver functionality. |
| ADAS Camera Power Rail | Infotainment USB Interface |
Use Scenario: Guards 12V input to image sensor power management ICs in front-facing cameras. IC Role / Device Role / Timing Role: Primary TVS on main camera module power entry point, mounted adjacent to connector. Use Value: Absorbs 600W pulses from hot-swap events and cable-induced surges while maintaining <0.5µA leakage to extend sleep-mode battery life. | Use Scenario: Protects USB VBUS line in head unit against 12V system coupling and human-body-model ESD. IC Role / Device Role / Timing Role: Unidirectional TVS between USB VBUS and GND, sized for 5V logic compatibility. Use Value: Delivers 26.0V clamping at 23.1A - sufficient to suppress coupled transients while avoiding false overvoltage shutdown of USB PD controllers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-Q | Same electrical specs; differs only in packaging marking (no "-13-F" tape/reel suffix) | No functional difference; identical AEC-Q101 qualification and thermal performance | Select when standard reel packaging suffices and Diodes' internal part number is preferred |
| SMCJ16A-Q | Higher 1500W PPK, larger SMC package (7.1mm × 6.2mm vs SMB's 3.94mm × 5.59mm) | Better for higher-energy transients but requires 2.5× PCB area; not drop-in compatible | Choose only if system-level testing confirms need for >600W surge handling and board space permits SMC footprint |
Compared with SMBJ16A-Q, SMBJ16AQ-13-F offers identical protection performance with optimized tape-and-reel logistics for automated SMT assembly; versus SMCJ16A-Q, it trades peak power for compactness - making it optimal for space-constrained ECUs and camera modules where 600W meets ISO7637-2 requirements.

FAQ
What is the clamping voltage of SMBJ16AQ-13-F at its rated peak pulse current?
The SMBJ16AQ-13-F has a maximum clamping voltage (VC) of 26.0V when subjected to a 10/1000µs waveform at its rated peak pulse current of 23.1A. This value is measured per REA-defined pulse conditions and guarantees voltage limiting during ISO7637-2 transients, ensuring protected ICs remain within safe operating limits.
Is SMBJ16AQ-13-F suitable for bidirectional signal lines like CAN or LIN?
No - SMBJ16AQ-13-F is unidirectional and must be used with cathode tied to the protected line and anode to ground. For bidirectional buses such as CAN, a bi-directional variant like SMBJ16CAQ-13-F (with "C" suffix) is required to clamp both positive and negative transients symmetrically.
How does SMBJ16AQ-13-F meet automotive reliability requirements?
SMBJ16AQ-13-F is AEC-Q101 qualified, manufactured in IATF 16949-certified facilities, and PPAP-capable. It undergoes stress testing including high-temperature operating life (HTOL), temperature cycling (TC), unbiased highly accelerated stress test (UHAST), and ESD per HBM/MM/CDM standards - validating performance across −55°C to +175°C junction temperatures.
What is the steady-state power dissipation rating and thermal derating behavior?
SMBJ16AQ-13-F has a steady-state power dissipation (PM(AV)) of 5.0W at TL = +75°C. Its thermal derating is linear at 4.8W/°C above +25°C ambient, meaning usable power drops to ~2.6W at +80°C ambient - a key consideration for under-hood placement near heat sources.
