Product details
Overview
3.0C110CA-M3 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, designed for high-energy surge protection with 3000 W peak pulse power (10/1000 μs), 110 V stand-off voltage, and 177 V clamping voltage at 16.9 A. It protects MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment against lightning and inductive switching transients.
For engineers reviewing the 3.0C110CA-M3 datasheet, 3.0C110CA-M3 pinout, 3.0C110CA-M3 application, or 3.0C110CA-M3 equivalent, this page delivers verified electrical specs, SMC package mechanical data, bidirectional clamping behavior, ESD immunity (30 kV HBM), and real-world protection use cases without generic assumptions.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds 110 V (VWM), it avalanches at 122–135 V (VBR), limiting transient voltage to ≤177 V (VC) at 16.9 A IPPM. Its bidirectional symmetry enables AC-line and differential-signal protection without polarity concerns.
It meets J-STD-020 MSL Level 1, supports 260 °C reflow, and achieves 30 kV contact-mode ESD immunity per IEC 61000-4-2 - critical for robust deployment in unshielded industrial interfaces and outdoor telecom nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 110 V - maximum continuous reverse operating voltage before conduction begins; sets system-level overvoltage trip threshold |
| VBR min/max | 122 V / 135 V at 1 mA - guaranteed avalanche onset range ensures predictable turn-on across temperature and unit variation |
| VC @ IPPM | 177 V at 16.9 A (10/1000 μs) - clamping voltage defines worst-case stress on downstream components during surge events |
| PPPM | 3000 W (10/1000 μs) - peak energy-handling capability determines survivability against common lightning-induced surges |
| TJ max | +175 °C - extended junction temperature rating enables operation in high-ambient environments like base station enclosures |
| ESD immunity | 30 kV HBM (contact/air) - qualifies for direct interface protection in handheld and field-deployable equipment |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads, MSL Level 1, 260 °C reflow compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked end) | Transient current sink (bidirectional device has no functional cathode/anode distinction) | Both terminals behave identically under reverse or forward surge; marking is for mechanical orientation only |
| Anode (unmarked end) | Transient current source (functionally identical to cathode in bidirectional mode) | No polarity-dependent behavior - symmetrical clamping ensures protection regardless of signal direction or DC bias |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines, differential buses (e.g., RS-485), and floating sensor outputs without external polarity management |
| 3000 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth, 2 kV line-line) without degradation when properly heatsinked |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns rise time), improving protection margin for sensitive gate drivers |
| MSL Level 1 rating | Eliminates bake-out requirement prior to SMT assembly, reducing manufacturing cost and cycle time |
Applications
| Industrial Motor Drives | Telecom Power Feeds |
|---|---|
Use Scenario: Protection of gate driver inputs and feedback sensing circuits against voltage spikes from IGBT switching and cable discharge. IC Role / Device Role / Timing Role: Shunt TVS device clamping transient energy before it reaches low-voltage control ICs. Use Value: Prevents latch-up or permanent damage to isolated gate drivers (e.g., Si823x) during 100 A inductive kick events. | Use Scenario: Surge suppression on -48 V DC power feeds entering remote radio units (RRUs) and DSLAM line cards. IC Role / Device Role / Timing Role: Primary overvoltage clamp on telecom power input rails upstream of DC/DC converters. Use Value: Limits rail voltage to ≤177 V during 10/1000 μs surges, preserving input capacitor lifetime and preventing converter shutdown. |
| Automotive Body Control Modules | Industrial Sensor Signal Conditioning |
Use Scenario: Protection of LIN bus transceivers and microcontroller I/O pins against load dump and ISO 7637-2 pulse 5a transients. IC Role / Device Role / Timing Role: Fast-response shunt suppressor placed at connector entry point. Use Value: Clamps 12 V system transients to safe levels within <1 ns, meeting OEM EMC requirements without added filtering complexity. | Use Scenario: Shielding analog output lines (4–20 mA, 0–10 V) of pressure/temperature sensors from EFT and surge coupling in factory automation. IC Role / Device Role / Timing Role: Bidirectional voltage limiter on sensor output path to preserve signal integrity. Use Value: Maintains sub-0.1% full-scale error during 1 kV EFT bursts by limiting excursion to ≤177 V at sensor amplifier input. |
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 | Lower PPPM (600 W), same VWM/VBR range, SMB package (smaller footprint, lower thermal mass) | Not suitable for IEC 61000-4-5 Level 4; limited to Level 2/3 surges and lower-energy EFT events | Select when board space is constrained and surge threat level is ≤1 kV line-earth |
| SMCJ110CA | Identical PPPM (3000 W), same SMC package, but higher VC (187 V at 16.9 A) and wider VBR tolerance (122–147 V) | Higher clamping voltage reduces protection margin for 3.3 V/5 V logic; acceptable for 12 V+ systems with >10 V headroom | Choose when sourcing flexibility is prioritized and 10 V additional clamping margin is acceptable |
Compared with SMBJ110CA and SMCJ110CA, the 3.0C110CA-M3 delivers tighter VBR (122–135 V), lower VC (177 V), and guaranteed 30 kV ESD rating - making it optimal for high-reliability industrial and telecom designs where clamping precision and surge margin are critical.

FAQ
What is the clamping voltage of the 3.0C110CA-M3 under a 10/1000 μs surge?
The 3.0C110CA-M3 clamps to a maximum of 177 V when subjected to its rated peak pulse current of 16.9 A with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet revision 09-Jan-2024, ensuring predictable overvoltage limiting for downstream circuitry.
Is the 3.0C110CA-M3 suitable for bidirectional signal line protection?
Yes, the 3.0C110CA-M3 is explicitly bidirectional, with symmetrical breakdown characteristics - meaning it provides identical clamping performance whether voltage transients occur in positive or negative polarity. This makes it ideal for protecting differential interfaces like RS-485, CAN, or analog sensor outputs without polarity constraints.
Does the 3.0C110CA-M3 meet industry-standard ESD requirements?
Yes, the 3.0C110CA-M3 is rated for 30 kV human-body-model (HBM) ESD immunity in both contact and air-discharge modes per IEC 61000-4-2. This exceeds standard industrial and telecom immunity requirements and is validated in the official Vishay test report referenced in document 98266.
What is the thermal resistance of the 3.0C110CA-M3, and how does it affect layout?
The 3.0C110CA-M3 has RthJA = 90 °C/W (JEDEC 51-2A, FR4, 2 oz copper) and RthJM = 4.0 °C/W (JEDEC 51-14). These values require minimum 10 mm² copper pour per terminal for sustained surge duty; insufficient copper increases junction temperature and degrades clamping consistency during repeated transients.
How does the 3.0C110CA-M3 differ from the SMCJ110CA in practical design?
The 3.0C110CA-M3 offers tighter VBR (122–135 V vs. 122–147 V), lower clamping voltage (177 V vs. 187 V at 16.9 A), and guaranteed 30 kV HBM ESD rating - all confirmed in Vishay's published specifications. These differences directly improve protection margin for 3.3 V/5 V logic interfaces and reduce risk of false triggering in precision analog circuits.
