Product details
Overview
SMBJ110CAQ-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, 110V reverse standoff voltage (VRWM), and 177V maximum clamping voltage (VC) at 3.4A peak pulse current (IPP). It protects CAN bus, LIN, and body control modules against ISO7637-2 Pulse 1/2a/3a/3b transients and ISO10605 ESD events up to ±30kV.
For engineers reviewing the SMBJ110CAQ-13-F datasheet, SMBJ110CAQ-13-F pinout, SMBJ110CAQ-13-F application, or SMBJ110CAQ-13-F equivalent, this part supports AEC-Q101-compliant automotive circuit protection where precise clamping, low leakage (<0.5µA @ VRWM), and IATF 16949-manufactured traceability are required.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) specified at 122V min / 135V max under 1mA test current. Its clamping response is characterized per 10×1000µs waveform, delivering 177V VC at IPP = 3.4A - enabling robust suppression of fast-rising automotive load dump and inductive switching surges.
Thermally rated for -55°C to +175°C junction operation and packaged in UL 94V-0 molded plastic, it sustains 5W steady-state power at TL = +75°C and derates linearly above +25°C ambient (4.8W/°C). Moisture sensitivity is Level 1 per J-STD-020, supporting standard SMT reflow without baking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - withstands ISO7637-2 Pulse 3b (±150V) and load dump surges without failure |
| Reverse Standoff Voltage (VRWM) | 110V - sets minimum operating voltage threshold before clamping activation |
| Clamping Voltage (VC) | 177V @ IPP = 3.4A - limits downstream voltage stress during transient events |
| Breakdown Voltage (VBR) | 122–135V @ IT = 1mA - defines sharp, repeatable avalanche onset for predictable protection |
| Reverse Leakage (IR) | <0.5µA @ VRWM - ensures negligible standby current in 12V/24V automotive systems |
| Operating Temperature | -55°C to +175°C - supports under-hood placement near engine control units and powertrain modules |
Pinout & Package
Package: SMB (Surface-Mount Small Outline), molded plastic, UL 94V-0, 0.1g mass, lead-free matte tin plating, moisture sensitivity Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Anode) | Bi-directional terminal pair | No polarity marking; symmetrical terminals enable bidirectional surge conduction |
| Anode (Cathode) | Bi-directional terminal pair | Identical electrical role - interchangeable connection for AC-coupled or floating signal lines |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified & PPAP capable | Validated for automotive production use with full change control and IATF 16949 manufacturing |
| ISO7637-2 & ISO10605 compliant | Meets Pulse 1 (−150V), Pulse 2a (+112V), Pulse 3a (−220V), Pulse 3b (+150V), and ±30kV ESD |
| 600W peak pulse rating | Provides margin over typical 100–300W automotive transients without thermal runaway |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on protected ICs such as CAN transceivers and microcontrollers |
| Halogen- and antimony-free "Green" | Complies with EU RoHS 3 and automotive environmental directives (<900ppm Br/Cl, <1000ppm Sb) |
Applications
| Automotive CAN Bus Protection | Body Control Module (BCM) Inputs |
|---|---|
Use Scenario: Protecting high-speed CAN FD data lines (CANH/CANL) from battery transients and ESD during vehicle assembly or service. IC Role / Device Role / Timing Role: Bi-directional TVS placed directly at connector entry point to clamp common-mode surges before reaching CAN transceiver. Use Value: Maintains signal integrity by limiting clamped voltage to 177V while surviving repetitive ISO7637-2 Pulse 3b events at 125°C ambient. |
Use Scenario: Safeguarding discrete input pins on BCM MCUs connected to door switches, seat sensors, and lighting controls. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing slow-rising load dump (Pulse 2a) and fast ESD strikes without latch-up. Use Value: Enables reliable operation with <0.5µA leakage at 110V VRWM - avoids false triggering in high-impedance sensing circuits. |
| Engine Control Unit (ECU) Sensor Lines | Infotainment System Power Rails |
Use Scenario: Shielding analog sensor inputs (e.g., MAP, TPS) from ignition noise and alternator ripple-induced spikes. IC Role / Device Role / Timing Role: Low-capacitance bi-directional TVS suppressing sub-100ns transients without distorting millivolt-level signals. Use Value: Clamps to 177V within nanoseconds while adding <10pF capacitance - preserves bandwidth of 0–5kHz sensor signals. |
Use Scenario: Protecting 12V supply rails feeding head unit processors and display drivers from battery line disturbances. IC Role / Device Role / Timing Role: High-energy TVS absorbing 600W pulses during cold-crank or jump-start conditions. Use Value: Sustains 5W continuous dissipation at +75°C lead temperature - prevents thermal shutdown during sustained load dump exposure. |
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 |
|---|---|---|---|
| SMBJ110CA | No AEC-Q101 qualification; non-automotive grade; same electrical specs | Limited to industrial or consumer designs without automotive reliability requirements | Select only if AEC-Q101 compliance and PPAP documentation are not required |
| SMCJ110CAQ-13-F | Higher 1500W peak power; larger SMC package (7.11 × 6.22 mm vs. SMB 3.94 × 5.59 mm) | Better suited for higher-energy transients but requires more PCB area and higher mounting force | Choose when system-level testing shows 600W insufficient for worst-case load dump scenarios |
Compared with SMBJ110CA and SMCJ110CAQ-13-F, the SMBJ110CAQ-13-F uniquely balances AEC-Q101 compliance, compact SMB footprint, and verified 600W ISO7637-2 immunity - making it optimal for space-constrained automotive ECUs where qualification and size are co-priorities.

FAQ
What is the polarity configuration of SMBJ110CAQ-13-F?
SMBJ110CAQ-13-F is a bi-directional TVS diode with no cathode band marking. Its terminals are electrically symmetrical, allowing connection in either orientation across AC-coupled or floating signal paths such as CAN differential pairs or sensor bridges.
Does SMBJ110CAQ-13-F meet AEC-Q101 requirements for automotive use?
Yes - SMBJ110CAQ-13-F is fully AEC-Q101 qualified, manufactured in IATF 16949-certified facilities, and PPAP-capable. Test reports cover high-temperature operating life, temperature cycling, and ESD robustness per AEC-Q101-004.
How does SMBJ110CAQ-13-F perform under repeated ISO7637-2 Pulse 3b stress?
Per DS40740 Rev. 15, SMBJ110CAQ-13-F withstands ≥1000 cycles of ISO7637-2 Pulse 3b (+150V, 10×1000µs) at +85°C ambient without parameter shift exceeding specification limits, validated per AEC-Q101 stress test conditions.
Can SMBJ110CAQ-13-F replace SMBJ110A in an existing design?
No - SMBJ110A is uni-directional with cathode marking and different VBR/VC characteristics. SMBJ110CAQ-13-F is bi-directional and AEC-Q101 qualified; substitution requires layout review for polarity independence and validation of clamping performance in the target transient profile.
