Product details
Overview
SMCJ110CAQ-13-F from Diodes Incorporated is a bidirectional 1,500W automotive transient voltage suppressor (TVS) diode in SMC package, with 110V reverse standoff voltage (VRWM), 177V clamping voltage (VC) at 8.4A peak pulse current (IPP), and AEC-Q101 qualification for under-hood power line protection against ISO7637-2 Pulse 1 (–100V), Pulse 3a (–150V), and ISO10605 ESD (±30kV).
For engineers reviewing the SMCJ110CAQ-13-F datasheet, SMCJ110CAQ-13-F pinout, SMCJ110CAQ-13-F application, or SMCJ110CAQ-13-F equivalent, this part is selected for high-energy surge suppression in 12V/24V automotive power networks where fast clamping (<1 ns), low leakage (<5 µA @ 110V), and IATF 16949 traceable manufacturing are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal/power lines without polarity constraints. Its glass-passivated junction ensures stable breakdown behavior over –55°C to +150°C junction temperature range and supports repetitive surge events per ISO7637-2 test profiles when derated per Fig. 1.
The device uses a planar junction structure optimized for low dynamic impedance (ZD ≈ 21.1 Ω, derived from VC/IPP = 177V/8.4A), delivering consistent clamping performance under 10/1000 µs transients. It meets stringent automotive reliability requirements including PPAP capability and halogen/antimony-free "Green" construction per Diodes' definitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single 10/1000 µs surges up to 1500W without failure |
| Reverse Standoff Voltage | 110V - blocks normal operating voltage up to 110V DC before clamping begins |
| Clamping Voltage | 177V @ 8.4A - limits transient voltage to ≤177V during 10/1000 µs pulse |
| Leakage Current | <5 µA @ 110V - negligible standby power loss and minimal impact on high-impedance circuits |
| Operating Temp Range | –55°C to +150°C - qualified for engine bay and transmission control unit environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability per stress test requirements |
| Package | SMC - surface-mount outline with 6.90 mm × 4.40 mm footprint and 2.50 mm pad pitch |
Pinout & Package
SMCJ110CAQ-13-F uses the SMC (DO-214AB) package: molded plastic body, UL 94V-0 rated, 0.21 g weight, cathode band omitted due to bidirectional construction. Terminals feature matte tin plating, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional surge path | No polarity marking; either terminal serves as input/output for transient energy diversion |
| Case (exposed pad) | Thermal conduction path | Not electrically connected; provides mechanical stability and heat dissipation to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| 1,500W peak pulse rating | Enables robust protection against severe load dump and inductive switching events in 24V systems |
| Glass-passivated die | Ensures stable VBR tolerance (122–135V) and long-term parameter drift < ±5% over lifetime |
| Bidirectional configuration | Eliminates need for polarity-aware layout in differential bus lines (e.g., LIN, CAN FD stubs) |
| AEC-Q101 qualification | Validates reliability for automotive production use with full change control and PPAP documentation |
| Halogen/antimony-free "Green" | Meets automotive OEM material compliance requirements (Br+Cl <1500 ppm, Sb <1000 ppm) |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) LIN Bus |
|---|---|
Use Scenario: Protects 12V supply rail of engine ECU against ISO7637-2 Pulse 1 (–100V) and Pulse 3a (–150V) induced by alternator load dump or relay coil collapse. IC Role / Device Role / Timing Role: Primary clamping element placed upstream of DC/DC converter input, responding within <1 ns to limit voltage excursion. Use Value: Prevents latch-up or permanent damage to downstream PMICs and microcontrollers by holding rail voltage ≤177V during 100 ms transients. | Use Scenario: Shields LIN transceiver PHY layer from ESD events (ISO10605 ±30kV air/contact discharge) and coupled noise on shared vehicle harnesses. IC Role / Device Role / Timing Role: Bidirectional shunt device placed across LIN bus pair (LIN-H/L), conducting surge current away from transceiver ESD structures. Use Value: Maintains LIN communication integrity by limiting differential voltage swing to <354V (2×177V) during worst-case common-mode transients. |
| Transmission Control Unit (TCU) Sensor Power | Advanced Driver Assistance Systems (ADAS) Camera Power |
Use Scenario: Safeguards 5V–12V sensor supply lines (e.g., crankshaft position, oil pressure) from battery reversal spikes and cranking transients in automatic transmission systems. IC Role / Device Role / Timing Role: Standoff-clamp TVS in parallel with LDO input, activated only during overvoltage events exceeding 110V. Use Value: Extends sensor IC lifetime by preventing gate oxide rupture in analog front-end amplifiers exposed to >100V surges. | Use Scenario: Protects 12V camera module power input in rear-view or surround-view systems subjected to repeated hot-swap and cable discharge events. IC Role / Device Role / Timing Role: First-line defense against ESD and conducted transients entering via FAKRA connector, placed immediately after connector PCB footprint. Use Value: Reduces field return rate by eliminating pixel corruption and boot failures caused by transient-induced MCU resets in image signal processors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC110-13-F | Same VRWM (110V), lower PPK (600W), higher VC (187V @ 3.2A) | Limited to lower-energy transients (e.g., infotainment USB ports); not suitable for power rail load dump | Select only for cost-sensitive non-power-rail applications with verified lower surge exposure |
| TPSMD110C | Same VRWM (110V), identical PPK (1500W), tighter VC spec (175V @ 8.6A), slightly larger SMC package variant | Compatible footprint but requires revalidation of thermal relief pads due to 0.2 mm height increase | Prefer for new designs requiring marginally better clamping or TI ecosystem alignment |
Compared with SAC110-13-F and TPSMD110C, SMCJ110CAQ-13-F delivers optimal balance of clamping precision (177V), automotive qualification depth (PPAP + IATF 16949), and proven field reliability in power rail roles-making it the default choice for critical 24V system nodes.

FAQ
What does the "C" suffix in SMCJ110CAQ-13-F signify?
The "C" denotes bidirectional configuration, meaning the device clamps symmetrically for both positive and negative transients without polarity dependence. Unlike unidirectional variants (e.g., SMCJ110AQ), it has no cathode band marking and is used where voltage polarity is undefined or alternating-such as across differential buses or floating power rails.
Can SMCJ110CAQ-13-F be used in 48V mild-hybrid systems?
No-it is rated for 110V standoff and 177V clamping, which is insufficient for 48V system load dump peaks exceeding 200V. For 48V applications, Diodes recommends SMCJ200CAQ-13-F (200V VRWM, 324V VC) or higher-voltage variants to maintain ≥20% margin above maximum expected transient amplitude.
Is the SMCJ110CAQ-13-F RoHS and REACH compliant?
Yes-this part meets EU Directive 2015/863/EU (RoHS 3) with lead-free matte tin plating and is fully compliant with REACH SVHC requirements. It is also halogen- and antimony-free per Diodes' "Green" definition (<900 ppm Br, <900 ppm Cl, <1000 ppm Sb), documented in their quality portal and packaging specifications.
How does moisture sensitivity level (MSL) affect handling?
Rated MSL Level 1 per J-STD-020, meaning the device has unlimited floor life at ≤30°C/85% RH and requires no baking prior to reflow. This simplifies SMT assembly for high-volume automotive production and eliminates moisture-related popcorning risk during standard lead-free reflow profiles.
