Product details
Overview
SMBJ180CAQ-13-F from Diodes Incorporated is a bi-directional automotive-grade transient voltage suppressor (TVS) diode in SMB package, rated for 600W peak pulse power, 180V reverse standoff voltage (VRWM), and 291.6V clamping voltage (VC) at 2.06A peak pulse current (IPP). It protects CAN/LIN bus interfaces, infotainment power rails, and ADAS sensor inputs against ISO7637-2 Pulse 1/2a/3a/3b transients and ISO10605 ESD events.
For engineers reviewing the SMBJ180CAQ-13-F datasheet, SMBJ180CAQ-13-F pinout, SMBJ180CAQ-13-F application, or SMBJ180CAQ-13-F equivalent, this device delivers verified AEC-Q101 qualification, IATF 16949 manufacturing, and precise clamping performance critical for 12V/24V automotive subsystems operating from −55°C to +175°C.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) specified at 200–220V (min/max) under 1mA test current. Its clamping behavior follows the 10×1000μs waveform standard per REA, ensuring predictable voltage limiting during fast-rising transients like load dump or inductive switching.
Thermal design is constrained by 5.0W steady-state power dissipation at TL = +75°C and 4.8W/°C derating above +25°C ambient. The device maintains full functionality across −55°C to +175°C junction temperature range, supporting under-hood and battery-management applications where thermal stability is non-negotiable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 10×1000μs surge without failure; defines maximum transient energy absorption capability |
| Reverse Standoff Voltage (VRWM) | 180V - maximum continuous DC or RMS voltage before significant leakage; sets operating margin above 24V system nominal |
| Clamping Voltage (VC) | 291.6V @ IPP = 2.06A - actual voltage seen by protected circuit during standardized transient; determines downstream component voltage rating |
| Breakdown Voltage (VBR) | 200–220V @ IT = 1mA - onset of avalanche conduction; ensures reliable turn-on before VC is reached |
| Leakage Current (IR) | ≤0.5µA @ VRWM - negligible standby power loss; avoids false triggering or battery drain in always-on modules |
| Operating Temperature | −55°C to +175°C - supports engine control units, transmission controllers, and EV battery monitoring in extreme thermal environments |
| AEC-Q101 Qualified | Yes - validated for automotive reliability including HTOL, TCT, ESD, and mechanical stress; enables PPAP submission |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic body with UL 94V-0 flammability rating, 0.1g mass, and matte tin-plated terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Cathode Band Absent) | Bi-directional terminal 1 | No polarity marking - symmetrical conduction path; connects to either side of differential signal line or power rail |
| Cathode (Cathode Band Absent) | Bi-directional terminal 2 | Identical to Anode - enables bidirectional clamping without orientation constraints during PCB placement |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power | Enables robust protection against high-energy ISO7637-2 Pulse 1 (−150V) and Pulse 3a (−220V) without degradation |
| AEC-Q101 qualification & IATF 16949 manufacturing | Guarantees automotive-grade reliability, change control, and supply chain traceability for Tier 1 production programs |
| Bi-directional architecture | Eliminates polarity concerns on AC-coupled lines (e.g., LIN bus, sensor differential pairs) and simplifies layout |
| RoHS-compliant, halogen-free "Green" construction | Meets EU Directive 2015/863/EU with Br+Cl <1500ppm and Sb <1000ppm; supports global environmental compliance |
Applications
| Automotive Infotainment Power Rail | CAN FD Transceiver Protection |

FAQ
What is the difference between SMBJ180CAQ-13-F and SMBJ180AQ-13-F?
The "C" suffix denotes bi-directional configuration, while the non-C version is uni-directional with a cathode band marking. SMBJ180CAQ-13-F clamps symmetrically across both polarities, making it suitable for AC-coupled or differential lines; SMBJ180AQ-13-F only clamps in reverse bias and requires correct orientation relative to ground.
Does SMBJ180CAQ-13-F meet ISO7637-2 Pulse 3b requirements?
Yes - its 291.6V clamping voltage at 2.06A is well below the +150V amplitude threshold for ISO7637-2 Pulse 3b, and its 600W peak power rating exceeds the energy content of that pulse when applied to typical line impedances.
Can SMBJ180CAQ-13-F be used in 48V mild-hybrid systems?
No - its 180V VRWM and 291.6V VC are designed for 12V/24V architectures. For 48V systems, Diodes recommends SMBJ330CAQ-13-F (330V VRWM) or SM8S330CA, which provide appropriate margin above 48V nominal and transient overshoot.
Is SMBJ180CAQ-13-F compatible with lead-free reflow profiles?
Yes - it is qualified for lead-free soldering per J-STD-020 Level 1 moisture sensitivity, with matte tin plating compatible with peak reflow temperatures up to 260°C and standard Pb-free thermal profiles (e.g., JEDEC J-STD-020D.01).
