Product details
Overview
SMBJ16CAQ-13-F from Diodes Incorporated is a bi-directional 600W automotive 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 for ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD protection in vehicle power-line interfaces.
For engineers reviewing the SMBJ16CAQ-13-F datasheet, SMBJ16CAQ-13-F pinout, SMBJ16CAQ-13-F application, or SMBJ16CAQ-13-F equivalent, this part supports robust surge immunity design in 12V/24V automotive ECUs, infotainment power rails, and CAN/LIN transceiver protection where bidirectional clamping, low leakage (<0.5µA), and IATF 16949 traceable sourcing are required.
Technical Context
This bi-directional TVS operates symmetrically across both polarities to clamp transients up to ±220V (Pulse 3a) and ±150V (Pulse 3b) without polarity dependence. Its 1.0mA breakdown test current and 17.8–19.7V VBR range ensure precise voltage thresholding under surge conditions.
Designed for surface-mount integration in space-constrained automotive modules, it delivers 600W peak pulse power per 10×1000µs waveform while maintaining <0.5µA reverse leakage at VRWM and operating from –55°C to +175°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 10×1000µs surges per ISO7637-2 without failure |
| Reverse Standoff Voltage | 16.0V - blocks normal 12V/24V system voltages while remaining inactive |
| Max Clamping Voltage | 26.0V @ 23.1A - limits downstream IC stress during Pulse 3a (–220V) |
| Breakdown Voltage Range | 17.8–19.7V @ 1.0mA - ensures reliable turn-on before damaging overvoltage |
| Reverse Leakage | <0.5µA @ 16V - negligible standby current in always-on vehicle modules |
| Operating Temperature | –55°C to +175°C - qualified for under-hood ECU placement and hot-cranking scenarios |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic body with UL 94V-0 rating, 0.1g mass, and matte tin lead finish. Moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal (bidirectional) | Accepts transient energy from either polarity; no cathode marking on bi-directional variant |
| Cathode | Input terminal (bidirectional) | Functions identically to Anode; symmetric clamping eliminates polarity dependency |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use with PPAP capability and IATF 16949 manufacturing control |
| ISO10605 compliance | Withstands 30kV air/contact discharge per C=150pF/R=330Ω test model |
| Bi-directional architecture | Clamps positive and negative transients equally-no orientation constraints during PCB layout |
| Lead-free & halogen-free | RoHS 3 compliant with <900ppm Br+Cl and <1000ppm Sb-meets global automotive environmental mandates |
Applications
| Body Control Module (BCM) | Infotainment Power Supply |
|---|---|
Use Scenario: Protects 12V input rail of BCM against load dump and alternator ripple. IC Role / Device Role / Timing Role: Primary bidirectional clamping device placed upstream of DC-DC converters and microcontrollers. Use Value: Limits voltage excursions to ≤26V during ISO7637-2 Pulse 2a (+112V), preventing latch-up in 3.3V/5V logic. | Use Scenario: Shields USB-C and HDMI power inputs in head units from ignition-induced spikes. IC Role / Device Role / Timing Role: Secondary surge suppression stage after primary fuse and LC filter. Use Value: Maintains <0.5µA leakage at 16V VRWM to avoid battery drain in parked vehicle mode. |
| CAN Transceiver Interface | ADAS Camera Power Input |
Use Scenario: Guards CANH/CANL lines against ESD events during connector mating/unmating. IC Role / Device Role / Timing Role: Low-capacitance (<100pF typical) bi-directional TVS directly at connector entry point. Use Value: Clamps ±30kV contact discharge (ISO10605) within 1ns, preserving signal integrity on 500kbps CAN bus. | Use Scenario: Secures 12V supply to front-facing camera module exposed to engine bay thermal cycling. IC Role / Device Role / Timing Role: High-temp-rated TVS mounted near camera connector to absorb cranking surges. Use Value: Operates reliably at +175°C junction temperature during sustained hot-soak conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | No -13-F tape-and-reel suffix; same electrical specs and AEC-Q101 qualification | Same automotive use cases but lacks standardized 3,000-piece reel packaging | Select when legacy procurement systems require non-F suffix or manual loading is acceptable |
| TPSMBS16C | Higher 1000W peak power; identical 16V VRWM and 26V VC but larger SMC package | Used where higher surge margin is needed (e.g., commercial vehicle alternators), not space-constrained PCBs | Choose only if 600W is insufficient and board area allows SMC footprint |
Compared with SMBJ16CA and TPSMBS16C, SMBJ16CAQ-13-F uniquely combines AEC-Q101, IATF 16949 traceability, RoHS 3 compliance, and optimized SMB footprint for high-volume automotive production-making it the preferred choice for Tier 1 ECU BOMs requiring full PPAP documentation and zero-defect supply chain control.

FAQ
What does the 'Q' suffix signify in SMBJ16CAQ-13-F?
The 'Q' denotes AEC-Q101 qualification and PPAP capability. This means the device has undergone rigorous automotive reliability testing-including temperature cycling, HTRB, and ESD-and is manufactured in an IATF 16949-certified facility with full change control documentation required by Tier 1 suppliers.
Is SMBJ16CAQ-13-F unidirectional or bidirectional?
SMBJ16CAQ-13-F is bi-directional, as confirmed by the 'C' in its part number (per Diodes datasheet DS40740 Rev. 15–2, page 3). It clamps transients equally on both polarities, eliminating PCB orientation concerns and simplifying layout for differential or AC-coupled lines like CAN or LIN.
What is the maximum clamping voltage at rated peak pulse current?
The maximum clamping voltage is 26.0V at 23.1A peak pulse current (10×1000µs waveform), per Electrical Characteristics table on page 3 of DS40740. This value ensures protected circuits remain below 28V absolute maximum ratings during ISO7637-2 Pulse 3a (–220V) events.
Does this TVS diode require heatsinking in standard automotive operation?
No heatsink is required for single-pulse operation. The device's 5.0W steady-state power dissipation at TL = +75°C and 4.8W/°C derating above +25°C ambient enables direct PCB mounting in most automotive applications, provided copper pour and thermal vias meet Diodes' recommended pad layout (SMB outline, page 5).
