Product details
Overview
3.0C14CA-M3 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features a 15.6–17.2 V breakdown voltage (VBR), 14 V stand-off voltage (VWM), 23.2 V max clamping voltage at 1000 A (10/1000 μs), 3000 W peak pulse power, and operates from –55 °C to +175 °C - used in industrial sensor interface protection.
For engineers reviewing the 3.0C14CA-M3 datasheet, 3.0C14CA-M3 pinout, 3.0C14CA-M3 application, or 3.0C14CA-M3 equivalent, key selection factors include bidirectional clamping capability, low incremental surge resistance, MSL Level 1 moisture sensitivity, halogen-free RoHS-compliant construction, and IEC 61000-4-2 ±30 kV ESD immunity.
Technical Context
This TVS diode employs silicon avalanche technology to provide fast response (<1 ns) and precise voltage clamping during transient events such as inductive switching surges or lightning-induced spikes. Its bidirectional architecture enables symmetric protection without polarity constraints on AC or differential lines.
The device delivers 3000 W peak pulse power under 10/1000 μs waveform and sustains 1000 A peak pulse current with 23.2 V clamping voltage - validated per ANSI/IEEE C62.35 standards. Thermal resistance junction-to-mount is 4.0 °C/W, supporting high-reliability operation in thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.6 V / 17.2 V - ensures reliable triggering above 14 V operating line while avoiding false trips during normal transients |
| VWM | 14 V - maximum continuous reverse voltage before leakage exceeds 2.0 μA, matching 12 V nominal bus systems |
| VC @ IPPM | 23.2 V at 1000 A (10/1000 μs) - limits downstream IC stress to safe levels during worst-case surge events |
| PPPM | 3000 W - supports robust protection against high-energy transients in industrial motor drives and power supplies |
| TJ max | +175 °C - enables deployment in under-hood automotive modules or high-ambient industrial enclosures |
| ESD immunity | ±30 kV (IEC 61000-4-2 contact/air) - eliminates need for additional ESD stages in sensor front-ends |
| Package | SMC (DO-214AB) - industry-standard footprint with 90 °C/W junction-to-ambient thermal resistance on FR4 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ14CA | Lower peak pulse power (600 W), smaller SMB package, 14 V VWM, 23.2 V VC @ 26.1 A | Rated for lower-energy transients; unsuitable for 1000 A surge environments | Select when board space is constrained and surge threat level is limited to IEC 61000-4-4 Level 3 |
| 1.5KE15CA | Higher VBR range (16.7–18.5 V), through-hole DO-201 package, same 3000 W rating but higher thermal resistance | Lacks MSL Level 1 compatibility and surface-mount efficiency; requires wave solder or hand-solder process | Choose only for legacy through-hole designs where rework flexibility outweighs SMT yield and thermal performance needs |
Compared with SMBJ14CA and 1.5KE15CA, the 3.0C14CA-M3 uniquely combines 3000 W surge capacity, SMC surface-mount scalability, MSL Level 1 reflow readiness, and bidirectional 14 V standoff - making it optimal for high-volume industrial and automotive PCBs requiring repeatable, high-energy transient immunity.

FAQ
What is the breakdown voltage range of the 3.0C14CA-M3?
The 3.0C14CA-M3 has a specified breakdown voltage (VBR) range of 15.6 V to 17.2 V at 1.0 mA test current. This ensures consistent turn-on behavior above the 14 V stand-off voltage while maintaining margin against normal operating fluctuations. The 3.0C14CA-M3 achieves this via controlled silicon avalanche characteristics verified per ANSI/IEEE C62.35.
Does the 3.0C14CA-M3 support lead-free reflow soldering?
Yes, the 3.0C14CA-M3 meets MSL Level 1 per J-STD-020 and is rated for a maximum peak reflow temperature of 260 °C, fully compatible with standard lead-free SAC305 processes. Its matte tin-plated leads comply with J-STD-002 and JESD22-B102, and the -M3 suffix confirms JESD201 Class 2 whisker resistance - critical for long-life industrial deployments.
What is the maximum clamping voltage of the 3.0C14CA-M3 under a 10/1000 μs surge?
The 3.0C14CA-M3 exhibits a maximum clamping voltage (VC) of 23.2 V when subjected to its rated 1000 A peak pulse current under the 10/1000 μs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during worst-case transient events - directly enabling safe operation of 24 V-rated logic and analog components.
Is the 3.0C14CA-M3 suitable for bidirectional signal line protection?
Yes, the 3.0C14CA-M3 is explicitly designed as a bidirectional TVS diode, with symmetrical clamping behavior in both polarities. Its unmarked SMC package and matched VBR/VC characteristics make it ideal for protecting differential interfaces (e.g., RS-485, CAN), AC-coupled sensors, or any line where voltage polarity reversal may occur - no external polarity routing required.
How does the 3.0C14CA-M3 perform under IEC 61000-4-2 ESD testing?
The 3.0C14CA-M3 is rated for ±30 kV contact discharge and ±30 kV air discharge per IEC 61000-4-2, verified using the human body model (C = 150 pF, R = 330 Ω). This performance eliminates the need for supplemental ESD protection on sensitive microcontroller I/O or sensor signal paths - the 3.0C14CA-M3 absorbs full discharge energy while maintaining sub-2.0 μA leakage at 14 V.
