Product details
Overview
3.0C15CA-M3 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 3000 W peak pulse power (10/1000 μs), 15 V stand-off voltage, and 24.4 V clamping voltage at 923 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in industrial and telecom power rails.
For engineers reviewing the 3.0C15CA-M3 datasheet, 3.0C15CA-M3 pinout, 3.0C15CA-M3 application, or 3.0C15CA-M3 equivalent, key selection criteria include bidirectional clamping capability, 175 °C max junction temperature, MSL Level 1 moisture sensitivity, and compliance with IEC 61000-4-2 ESD (30 kV contact/air).
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within picoseconds to transients induced by inductive switching or lightning surges. Its low incremental surge resistance and fast response time ensure minimal overvoltage exposure to downstream components.
The device uses an avalanche breakdown mechanism with precisely controlled VBR (16.7–18.5 V) and exhibits stable clamping performance across its full operating temperature range (−55 °C to +175 °C), validated under 10/1000 μs and 8/20 μs waveforms per ANSI/IEEE C62.35.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - Maximum continuous reverse operating voltage before leakage exceeds 2 μA; defines safe DC/AC rail margin. |
| VBR (min/max) | 16.7 V / 18.5 V - Breakdown voltage range at 1 mA test current; ensures reliable turn-on above nominal rail. |
| VC @ IPPM | 24.4 V at 923 A - Clamped voltage during 10/1000 μs transient; limits stress on protected ICs to safe levels. |
| PPPM | 3000 W - Peak pulse power handling capacity; supports robust protection against IEC 61000-4-5 level 4 surges. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in high-ambient industrial environments without derating. |
| ESD Rating | 30 kV (HBM, contact & air) - Meets IEC 61000-4-2; eliminates need for additional ESD stages in front-end interfaces. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, MSL Level 1, matte tin-plated leads solderable per J-STD-002/JESD 22-B102. Bidirectional polarity-no marking required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked band) | Anode-side terminal in bidirectional configuration | Terminal identity is symmetrical; either end serves as cathode depending on transient polarity-no fixed anode/cathode assignment. |
| Anode (unmarked end) | Cathode-side terminal in bidirectional configuration | Same physical terminal as above; conduction occurs symmetrically across both directions during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity constraints. |
| 3000 W peak pulse power (10/1000 μs) | Supports sustained surge energy dissipation in industrial motor drives and PoE-powered equipment. |
| Low clamping ratio (VC/VWM = 1.63) | Minimizes overvoltage overshoot relative to working voltage-critical for 15 V logic and analog supply rails. |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow without baking-reduces manufacturing overhead in high-volume SMT lines. |
| IEC 61000-4-2 compliant (30 kV) | Meets highest ESD immunity class for front-panel connectors and exposed I/O ports without external shielding. |
Applications
| Industrial Motor Drives | Telecom Power Feeds |
|---|---|
Use Scenario: Protection of gate drivers and current-sense amplifiers against back-EMF spikes from brushed/BLDC motor commutation. IC Role / Device Role: Shunt TVS placed across DC bus or gate drive traces to clamp inductive kick to ≤24.4 V. Use Value: Prevents latch-up or oxide rupture in 20 V-rated MOSFETs and op-amps by limiting transient excursion below absolute maximum ratings. | Use Scenario: Surge suppression on −48 V DC telecom power input prior to DC/DC converters and line cards. IC Role / Device Role: Primary-level TVS mounted at board edge to absorb IEC 61000-4-5 combination wave surges up to 3 kA. Use Value: Maintains uninterrupted operation during lightning-induced surges by dissipating 3000 W without degradation or thermal runaway. |
| Automotive Body Control Modules | Industrial Sensor Signal Conditioning |
Use Scenario: Protection of LIN/CAN transceiver power pins and microcontroller I/O against load dump and jump-start transients. IC Role / Device Role: Bidirectional TVS on 12 V supply rail to suppress ±100 V/100 ms load dump per ISO 7637-2 Pulse 5a. Use Value: Eliminates need for series resistors or zener clamps-reduces BOM count while meeting OEM EMC requirements. | Use Scenario: Guarding 4–20 mA current loop inputs and thermocouple amplifier front-ends in PLC analog modules. IC Role / Device Role: Low-capacitance (<100 pF at 0 V) TVS placed directly at connector entry to suppress EFT bursts and ESD. Use Value: Preserves signal integrity with <0.5 pF parasitic capacitance shift at 15 V bias-no gain/offset drift in precision measurement paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | Lower PPPM (600 W), same VWM (15 V), larger VC (24.4 V → 24.4 V but at lower IPPM = 24.5 A) | Not suitable for IEC 61000-4-5 level 4; limited to low-energy ESD/EFT only. | Select when cost sensitivity outweighs surge energy requirement and PCB space allows SMB footprint. |
| SMCJ15CA | Same package (SMC), identical VWM/VC, but rated for 1500 W (10/1000 μs)-half the energy handling of 3.0C15CA-M3 | Acceptable for mid-tier industrial equipment where 3 kA surges are not mandated. | Choose if legacy design uses SMCJ series and minor derating is acceptable; verify thermal margin at 175 °C ambient. |
Compared with SMBJ15CA and SMCJ15CA, the 3.0C15CA-M3 delivers double the surge energy capacity of SMCJ15CA and five times that of SMBJ15CA-enabling single-device compliance with IEC 61000-4-5 level 4 in space-constrained SMC layouts.

FAQ
What is the clamping voltage of the 3.0C15CA-M3 under a 10/1000 μs surge?
The 3.0C15CA-M3 clamps to 24.4 V at its rated peak pulse current of 923 A under a 10/1000 μs waveform. This value is guaranteed per the datasheet's Electrical Characteristics table and reflects worst-case performance at TA = 25 °C. The clamping voltage remains stable across its full operating temperature range due to low thermal coefficient design.
Is the 3.0C15CA-M3 unidirectional or bidirectional?
The 3.0C15CA-M3 is a bidirectional TVS diode, indicated by the "CA" suffix in its part number. It provides symmetrical clamping for both positive and negative transients without polarity orientation constraints-ideal for AC lines, differential signals, and floating grounds. No polarity marking is present on the SMC package.
Does the 3.0C15CA-M3 meet JEDEC moisture sensitivity requirements?
Yes, the 3.0C15CA-M3 meets MSL Level 1 per J-STD-020, with a maximum lead finish temperature of 260 °C. This allows indefinite floor life and compatibility with standard lead-free reflow profiles without pre-baking-critical for high-throughput SMT assembly in industrial and telecom manufacturing.
What is the maximum junction temperature rating for the 3.0C15CA-M3?
The 3.0C15CA-M3 has a maximum junction temperature (TJ) rating of +175 °C, enabling reliable operation in high-ambient environments such as motor control enclosures, outdoor telecom cabinets, and under-hood automotive applications. Thermal resistance values (RthJA = 90 °C/W, RthJM = 4.0 °C/W) support accurate thermal modeling in layout design.
How does the 3.0C15CA-M3 compare to standard Zener diodes for surge protection?
Unlike standard Zener diodes, the 3.0C15CA-M3 is optimized for transient suppression-not regulation-with lower dynamic impedance, faster response (<1 ps), and guaranteed 3000 W pulse power handling. Its avalanche structure sustains repeated high-current surges without parameter drift, whereas Zeners degrade rapidly under similar conditions and lack standardized surge waveform ratings.
