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 high-energy surge protection with 3000 W peak pulse power (10/1000 μs), 15.6–17.2 V breakdown voltage, and 23.2 V clamping voltage at 1000 A. It protects MOSFETs, ICs, and sensor signal lines in industrial and telecom power rails.
For engineers reviewing the 3.0C14CA-M3 datasheet, 3.0C14CA-M3 pinout, 3.0C14CA-M3 application, or 3.0C14CA-M3 equivalent, key selection criteria include clamping voltage at rated IPPM, bidirectional standoff capability (14 V), junction temperature rating (175 °C), and MSL Level 1 reflow compatibility.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within picoseconds to transients induced by inductive switching or ESD events. Its bidirectional architecture enables symmetrical clamping above ±14 V standoff without polarity constraints, and its low incremental surge resistance ensures stable voltage limiting under 1000 A 10/1000 μs pulses.
It meets IEC 61000-4-2 (30 kV contact/air discharge) and complies with J-STD-020 MSL Level 1 (260 °C peak reflow). Thermal performance is characterized by RthJA = 90 °C/W and RthJM = 4.0 °C/W, supporting reliable operation up to TJ = 175 °C in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.6 V / 17.2 V - Ensures precise breakdown activation above circuit operating voltage while avoiding false triggering |
| VWM | 14 V - Maximum continuous reverse working voltage; defines safe DC/AC operating margin before conduction |
| VC @ IPPM | 23.2 V @ 1000 A (10/1000 μs) - Clamping voltage limits downstream component stress during worst-case surge |
| PPPM | 3000 W - Sustains high-energy transients without failure; critical for industrial motor drive or telecom line protection |
| IPPM | 1000 A - Peak pulse current handling capacity directly determines survivability against lightning-induced surges |
| TJ max | 175 °C - Enables deployment in high-ambient environments such as enclosed power supplies or automotive under-hood modules |
| ESD Rating | 30 kV HBM (contact/air) - Provides robust immunity to human-body-model electrostatic discharge in assembly and field use |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads, MSL Level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked end) | Transient current sink (bidirectional) | No polarity marking on bidirectional types; terminals are functionally symmetric for AC or dual-rail protection |
| Anode | Transient current source (bidirectional) | Both terminals conduct equally during positive or negative overvoltage events; no dedicated anode/cathode bias required |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines or floating differential signals without external polarity management |
| 3000 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 surge immunity in industrial control inputs and power supply front-ends |
| 23.2 V clamping at 1000 A | Keeps protected ICs (e.g., microcontrollers, gate drivers) below absolute maximum ratings during 1000 A surge events |
| MSL Level 1 moisture sensitivity | Allows direct placement into standard SMT reflow profiles without baking or special handling |
| 175 °C maximum junction temperature | Permits operation in thermally constrained enclosures such as sealed power converters or outdoor telecom units |

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), same 14 V VWM, SMB package (smaller footprint, higher RthJA) | Suitable for lower-energy consumer interfaces; not rated for 3000 W industrial surges | Select 3.0C14CA-M3 when 10/1000 μs surge immunity ≥3000 W is required; SMBJ14CA fits space-constrained designs with lower threat levels |
| 1.5KE15CA | Higher VC (24.4 V), same VWM, axial-leaded DO-201 package, 1500 W rating | Limited to through-hole assembly; lacks MSL Level 1 reflow compatibility and modern halogen-free compliance | Choose 3.0C14CA-M3 for automated SMT production, high-reliability reflow, and full IEC 61000-4-2/4-5 compliance in new designs |
Compared with SMBJ14CA and 1.5KE15CA, the 3.0C14CA-M3 delivers 5× higher peak pulse power in an MSL Level 1–qualified SMC package, enabling robust, automated protection for industrial and telecom systems where 1000 A surge currents and 175 °C ambient operation are design requirements.

FAQ
What is the breakdown voltage range specified for the 3.0C14CA-M3?
The 3.0C14CA-M3 has a guaranteed breakdown voltage (VBR) range of 15.6 V to 17.2 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This tight tolerance ensures consistent activation threshold across production lots and supports reliable coordination with downstream overvoltage protection circuits in power supply designs.
Does the 3.0C14CA-M3 support lead-free reflow soldering?
Yes, the 3.0C14CA-M3 is qualified to MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 260 °C and features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Its halogen-free molding compound and RoHS-compliant construction make it fully compatible with standard lead-free SMT assembly processes.
How does the clamping voltage of the 3.0C14CA-M3 compare under different surge waveforms?
The 3.0C14CA-M3 clamps to 23.2 V at 1000 A for the 10/1000 μs waveform and to 30.0 V at 1000 A for the 8/20 μs waveform. The higher clamping voltage under the faster 8/20 μs pulse reflects greater dynamic impedance during shorter-duration, higher-di/dt events-critical for evaluating protection margins in lightning-surge scenarios per IEC 61000-4-5.
Is the 3.0C14CA-M3 suitable for bidirectional AC line protection?
Yes, the 3.0C14CA-M3 is explicitly designed as a bidirectional TVS diode with symmetrical clamping characteristics. Its lack of polarity marking and matched VBR/VC behavior for both polarities make it ideal for protecting AC-coupled signal paths, transformer-isolated interfaces, and dual-rail power domains without additional external components.
What is the thermal resistance from junction to ambient for the 3.0C14CA-M3?
The 3.0C14CA-M3 has a typical junction-to-ambient thermal resistance (RthJA) of 90 °C/W when mounted on a standard FR4 PCB with 2 oz. copper per JEDEC 51-2A. This value assumes the recommended SMC mounting pad layout; actual thermal performance depends on PCB copper area and airflow, and must be validated in the final mechanical design.
