Product details
Overview
SMBJ130CAQ-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, 130V reverse standoff voltage (VRWM), and 209V max clamping voltage (VC) at 2.9A peak pulse current (IPP). It protects CAN, LIN, and sensor interfaces in 12V/24V vehicle subsystems against ISO7637-2 Pulse 1/2a/3a/3b transients and ISO10605 ESD events.
For engineers reviewing the SMBJ130CAQ-13-F datasheet, SMBJ130CAQ-13-F pinout, SMBJ130CAQ-13-F application, or SMBJ130CAQ-13-F equivalent, this part is selected for AEC-Q101-compliant surge protection where bidirectional clamping, low leakage (<0.5µA @ VRWM), and IATF 16949-manufactured traceability are required in engine control, body electronics, and ADAS power domains.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) specified at 144V min / 159V max under 1.0mA test current. Its clamping performance is validated per 10×1000µs waveform, delivering 209V VC at IPP = 2.9A - enabling robust suppression of fast-rising transients without latch-up or thermal runaway.
Designed for automotive environments, it supports continuous operation from –55°C to +175°C junction temperature, with steady-state power dissipation of 5.0W at TL = +75°C and full derating above +25°C ambient (4.8W/°C). Moisture sensitivity is Level 1 per J-STD-020, and plating meets MIL-STD-202 solderability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 10×1000µs surges up to 2.9A without failure |
| Reverse Standoff Voltage (VRWM) | 130V - maximum continuous DC or RMS voltage before significant leakage |
| Clamping Voltage (VC) | 209V @ IPP = 2.9A - limits downstream circuit voltage during ISO7637-2 Pulse 3b (+150V) |
| Breakdown Voltage (VBR) | 144–159V @ IT = 1.0mA - defines precise avalanche onset threshold for bidirectional conduction |
| Leakage Current (IR) | <0.5µA @ VRWM - ensures negligible standby power loss in always-on vehicle modules |
| Operating Temperature | –55°C to +175°C - qualified for under-hood and transmission-control module placement |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic UL 94V-0 housing; weight ≈0.1g; cathode band omitted (bi-directional device).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Transient return path (bidirectional) | Connects to protected line; conducts during negative or positive overvoltage events |
| Cathode (Pin 2) | Transient return path (bidirectional) | Connects to protected line; symmetrically identical to Anode in bi-directional configuration |
Key Features
| Feature | Design Value |

| Lead-free, halogen-free "Green" construction | RoHS 3 compliant; <900ppm Br, <900ppm Cl, <1000ppm Sb - supports eco-design mandates |
| Low clamping ratio (VC/VRWM) | 1.61 - tight voltage margin enables protection of 130V-rated components with safety headroom |

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 |
|---|---|---|---|
| SMBJ130CA | No "Q" suffix - not AEC-Q101 qualified; RoHS compliant but not PPAP capable | Limited to non-safety-critical consumer or industrial designs | Select only if automotive change control and IATF 16949 traceability are not required |
| SMCJ130CAQ | SMC package (larger footprint); 1500W rating; same VRWM/VC specs | Higher power handling but incompatible PCB layout; requires redesign | Choose when surge energy exceeds 600W or thermal dissipation demands larger copper area |
Compared with SMBJ130CA and SMCJ130CAQ, the SMBJ130CAQ-13-F uniquely balances AEC-Q101 compliance, SMB footprint compatibility, and precise 130V/209V clamping for space-constrained automotive modules - making it optimal for CAN/LIN nodes where qualification and board real estate are co-constrained.

FAQ
What does the "Q" suffix signify in SMBJ130CAQ-13-F?
The "Q" denotes AEC-Q101 qualification - confirming full stress testing per automotive reliability standards, including HTGB, HTRB, TCT, and UHAST. It also indicates PPAP capability and production in IATF 16949-certified facilities, distinguishing it from commercial-grade SMBJ130CA variants.
Can SMBJ130CAQ-13-F be used in 24V truck systems?
Yes - its 130V VRWM and 209V VC provide sufficient margin above typical 24V nominal systems (up to ~32V during load dump), and it is explicitly rated for ISO7637-2 Pulse 1 (–150V) and Pulse 3a (–220V), which cover heavy-duty vehicle transient profiles.
Is the SMBJ130CAQ-13-F unidirectional or bidirectional?
It is bi-directional, as indicated by the "C" in the part number (SMBJ130CAQ-13-F). Unlike uni-directional versions, it has no cathode band marking and clamps symmetrically for both positive and negative transients - essential for protecting AC-coupled or differential buses like CAN.
What is the maximum allowable PCB pad temperature during reflow?
The SMBJ130CAQ-13-F supports standard lead-free reflow profiles per J-STD-020. Peak temperature must not exceed 260°C for ≤30 seconds, with ramp rates ≤3°C/s. The device's moisture sensitivity level is 1, so baking prior to assembly is not required.
