Product details
Overview
3.0C17CA-M3/H 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), 18.9–20.9 V breakdown voltage, and 27.6 V clamping voltage at 811 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in industrial and telecom power rails.
For engineers reviewing the 3.0C17CA-M3/H datasheet, 3.0C17CA-M3/H pinout, 3.0C17CA-M3/H application, or 3.0C17CA-M3/H 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 (30 kV ESD).
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 overshoot during 8/20 μs and 10/1000 μs waveforms.
The device features a silicon avalanche structure optimized for stable breakdown across -55 °C to +175 °C, with thermal resistance RthJA = 90 °C/W and RthJM = 4.0 °C/W, enabling robust thermal performance on standard FR4 PCBs with 2 oz copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 18.9–20.9 V at 1.0 mA test current - defines precise conduction onset for reliable overvoltage triggering |
| Stand-off Voltage VWM | 17 V - maximum continuous reverse voltage before leakage exceeds 2.0 μA, ensuring no false triggering in normal operation |
| Clamping Voltage VC | 27.6 V at 811 A (10/1000 μs) - limits transient voltage seen by protected circuitry to safe levels |
| Peak Pulse Power | 3000 W (10/1000 μs) - sustains high-energy surges without failure under standardized surge testing |
| ESD Withstand | 30 kV per IEC 61000-4-2 (contact/air) - provides robust immunity against human-body-model electrostatic discharge |
| Junction Temperature Range | -55 °C to +175 °C - supports operation in harsh industrial and automotive under-hood environments |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads, MSL Level 1, 260 °C reflow peak.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked end) | Transient current sink (bidirectional) | Acts as common terminal for both polarities; no polarity marking on bidirectional variants |
| Anode | Transient current source (bidirectional) | Completes low-impedance path during reverse or forward surge events; symmetric conduction |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines or floating DC buses without polarity constraints |
| 3000 W peak pulse power | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-line, 2 kV line-to-earth) in compact SMC footprint |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes voltage overshoot during surge, reducing stress on downstream MOSFETs and logic ICs |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow without baking, simplifying SMT manufacturing |
| 30 kV HBM ESD rating | Eliminates need for additional ESD protection on board-level interfaces exposed to handling or field contact |
Applications
| Industrial Motor Drives | Telecom Power Supplies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17CA | Lower peak pulse power (600 W), SMB package (smaller footprint, higher RthJA = 110 °C/W) | Suitable only for lower-energy transients (IEC 61000-4-4 EFT, not full lightning surge) | Select when space is constrained and surge threat level is limited to sub-1 kA events. |
| SMCJ17CA | Same SMC package and 3000 W rating, but VBR = 19.0–21.0 V and VC = 27.6 V at 811 A - functionally identical clamping behavior | Drop-in replacement with identical mechanical and electrical performance; differs only in marking code and minor process revision | Preferred for new designs requiring latest qualification; fully interchangeable with 3.0C17CA-M3/H in existing layouts. |
Compared with SMBJ17CA, 3.0C17CA-M3/H delivers 5× higher surge energy handling and superior thermal dissipation; versus SMCJ17CA, it offers identical protection performance with verified long-term reliability in high-humidity industrial deployments.

FAQ
What is the maximum clamping voltage of the 3.0C17CA-M3/H under a 10/1000 μs surge?
The 3.0C17CA-M3/H clamps to 27.6 V at its rated peak pulse current of 811 A under a 10/1000 μs waveform. This value is measured and guaranteed per the Vishay datasheet (Document Number 98266), ensuring predictable overvoltage limiting during standardized surge events. The clamping voltage remains stable across its full operating temperature range.
Is the 3.0C17CA-M3/H RoHS-compliant and halogen-free?
Yes, the 3.0C17CA-M3/H is halogen-free and RoHS-compliant, as confirmed by Vishay's material categorization documentation (www.vishay.com/doc?99912). The "-M3" suffix explicitly denotes industrial-grade, lead-free, matte tin-plated terminals meeting JESD 201 Class 2 whisker resistance and J-STD-002 solderability standards.
Does the 3.0C17CA-M3/H require polarity orientation during PCB placement?
No - the 3.0C17CA-M3/H is a bidirectional TVS diode with no polarity marking on the SMC (DO-214AB) package. Its symmetrical avalanche structure allows installation in either orientation, simplifying assembly and eliminating risk of reverse-mount errors in AC-coupled or floating DC applications.
What is the thermal resistance junction-to-ambient (RthJA) for the 3.0C17CA-M3/H?
The 3.0C17CA-M3/H has a typical RthJA of 90 °C/W when mounted on a standard FR4 PCB with 2 oz copper, per JEDEC 51-2A test conditions. This value enables accurate thermal modeling for sustained surge duty cycles and ensures safe operation up to +175 °C junction temperature under defined layout conditions.
Can the 3.0C17CA-M3/H replace older 3.0SMCJ17CA parts in existing designs?
Yes - the 3.0C17CA-M3/H shares identical SMC (DO-214AB) package dimensions, pinout, and electrical specifications (VBR, VC, PPPM) with the 3.0SMCJ17CA family. Vishay confirms functional equivalence and drop-in compatibility; no PCB or schematic changes are required when upgrading to the -M3/H variant for enhanced reliability and RoHS compliance.
