Product details
Overview
3.0SMCJ110CA-13 from Diodes Incorporated is a bi-directional 3000W surface-mount transient voltage suppressor (TVS) designed for high-energy surge protection in DC power rails and signal lines. It features a 110V reverse standoff voltage, 177V maximum clamping voltage at 16.9A peak pulse current, and IEC-61000-4-2 ESD immunity of 30kV (air/contact). It is used in industrial power supplies to protect downstream DC-DC converters from lightning-induced surges.
For engineers reviewing the 3.0SMCJ110CA-13 datasheet, 3.0SMCJ110CA-13 pinout, 3.0SMCJ110CA-13 application, or 3.0SMCJ110CA-13 equivalent, key selection criteria include clamping voltage margin relative to protected IC VMAX, peak pulse current capability under 10/1000μs waveform, thermal derating above +25°C ambient, and SMC package solderability per MIL-STD-202.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with no cathode band marking. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<5μA at 110V), critical for low-power standby circuits.
It delivers 3000W peak pulse power under standardized 10×1000μs waveform per REA, with thermal derating beginning at +25°C (100% rating) and falling to ~50% at +125°C per Fig. 1 - essential for under-hood automotive or enclosed industrial enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000W - sustains single 10×1000μs transients without failure, enabling robust protection against lightning surges (IEC 61000-4-5 Level 4). |
| Reverse Standoff Voltage (VRWM) | 110V - maximum continuous DC or RMS voltage before significant leakage; sets minimum operating rail margin for 120VAC-derived DC buses. |
| Max Clamping Voltage (VC) | 177V @ 16.9A - limits transient voltage seen by downstream components; must be below absolute max rating of protected ICs (e.g., MOSFET drain or controller VDD). |
| Breakdown Voltage (VBR) | 122–134.8V @ 1mA - tight 10.5% tolerance ensures predictable turn-on; enables precise coordination with upstream fuses or current limiters. |
| ESD Rating | 30kV air / 30kV contact (IEC-61000-4-2) - protects human-accessible ports (e.g., terminal blocks, connectors) without external spark gaps. |
| Operating Temperature | −55°C to +150°C - supports deployment in extended-temperature environments including motor drives and outdoor telecom equipment. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 flammability rating; moisture sensitivity level 1 per J-STD-020; matte tin-plated leads solderable per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Input/Line Terminal | One side of symmetrical bi-directional junction; connects to protected line (e.g., +120VDC bus); no polarity marking required. |
| Cathode (K) | Input/Line Terminal | Other side of symmetrical bi-directional junction; connects to same protected line as Anode; terminals are functionally interchangeable. |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional architecture | Enables single-device protection of AC-coupled or floating DC lines (e.g., RS-485, CAN bus, transformer secondaries) without polarity concerns. |
| Glass-passivated die | Ensures long-term parameter stability and low leakage drift over temperature and lifetime - critical for safety-critical power monitoring circuits. |
| 3000W peak pulse rating | Supports coordination with Type II/III SPDs in multi-stage protection schemes where this device serves as the final-clamp stage near ICs. |
| RoHS-compliant & "Green" | Meets <900ppm Br/Cl and <1000ppm Sb requirements - satisfies environmental compliance for EU, China RoHS, and automotive PPAP submissions. |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: Protecting 120VDC output of an isolated flyback converter feeding PLC I/O modules. IC Role / Device Role / Timing Role: Final-clamp TVS placed immediately after output filter capacitor, shunting surge energy before it reaches downstream DC-DC regulators and microcontrollers. Use Value: 177V clamping ensures protected ICs with 200V absolute max ratings remain within safe operating area during 1kV/0.5Ω IEC 61000-4-5 surges. |
Use Scenario: Safeguarding LIN bus transceivers and power management ICs in BCMs exposed to load dump and jump-start events. IC Role / Device Role / Timing Role: Bi-directional suppression on 12V battery rail, absorbing reverse-polarity transients and positive spikes up to 120V. Use Value: −55°C to +150°C operation allows placement near high-temperature engine bay components without derating loss. |
| Telecom Remote Radio Unit (RRU) | Renewable Energy Inverter DC Link |
Use Scenario: Shielding Ethernet PHY power pins and PoE interface circuitry from induced surges in outdoor base station cabinets. IC Role / Device Role / Timing Role: Primary surge clamp on 48V PoE power input, coordinated with upstream GDT and series impedance to meet IEC 61000-4-5 Class B. Use Value: 30kV ESD rating eliminates need for additional discrete ESD diodes on accessible RJ45 ports. |
Use Scenario: Protecting gate drivers and sensing amplifiers connected to 1000V DC link in solar string inverters. IC Role / Device Role / Timing Role: Secondary-level TVS on auxiliary supply rails derived from DC link, limiting transients coupled via shared ground paths. Use Value: 110V VRWM provides sufficient margin above 96V nominal auxiliary rail while maintaining fast response to fast-rising switching noise. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA-T | 2000W peak power, same VRWM and VC, SMB package (smaller footprint, lower thermal mass). | Limited to lower-energy surges; unsuitable for IEC 61000-4-5 Level 4 or repeated surge exposure. | Select when board space is constrained and surge threat level is limited to IEC 61000-4-2/4-4 only. |
| 1.5SMC110CA | 1500W peak power, identical VRWM/VC, same SMC package but lower PPK rating. | Inadequate for sustained 3000W transients; may fail catastrophically under full lightning surge stress. | Use only in cost-sensitive, non-safety-critical consumer applications with verified low-surge environments. |
Compared with SMBJ110CA-T and 1.5SMC110CA, the 3.0SMCJ110CA-13 delivers 50% higher surge energy handling in the same SMC footprint - enabling single-device compliance with industrial and automotive surge standards without redesigning PCB layout or thermal relief.

FAQ
What is the maximum clamping voltage of the 3.0SMCJ110CA-13 under standard test conditions?
The maximum clamping voltage (VC) is 177V at 16.9A peak pulse current, measured using the standardized 10×1000μs waveform per REA. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 3.0SMCJ110CA-13 unidirectional or bidirectional, and how is polarity identified?
The 3.0SMCJ110CA-13 is a bi-directional TVS diode with symmetrical breakdown characteristics in both polarities. It has no cathode band or polarity marking - both terminals are electrically identical and interchangeable in circuit layout.
Can this TVS be used in automotive applications, and what qualifications does it meet?
While the standard 3.0SMCJ110CA-13 is not AEC-Q200 qualified, Diodes offers automotive-grade variants (e.g., 3.0SMCJ110CAQ-13) manufactured in IATF 16949-certified facilities and qualified to AEC-Q200. These versions support PPAP documentation and are intended for body electronics and infotainment systems.
What is the thermal derating behavior above +25°C ambient temperature?
Per Figure 1 in DS30818 Rev. 18, the device maintains 100% peak pulse power at +25°C, linearly derating to approximately 50% at +125°C. At +150°C, derating reaches ~35%, meaning peak pulse current capability drops to ~5.9A - a critical consideration for thermally dense power designs.
