Product details
Overview
3.0C17CA-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 10/1000 μs peak pulse power rating of 3000 W, breakdown voltage range of 18.9–20.9 V at 1 mA test current, and clamps to ≤27.6 V at 811 A peak pulse current.
For engineers reviewing the 3.0C17CA-M3 datasheet, 3.0C17CA-M3 pinout, 3.0C17CA-M3 application, or 3.0C17CA-M3 equivalent, this device is selected for high-energy surge protection in industrial sensor interfaces, DC power rails, and telecom line cards where bidirectional clamping, low clamping voltage, and MSL Level 1 reflow compatibility are required.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector with bidirectional avalanche conduction. Its 17 V standoff voltage (VWM) and 18.9–20.9 V breakdown (VBR) define its turn-on threshold, while its 27.6 V clamping voltage (VC) at 811 A (10/1000 μs) ensures robust overvoltage limiting under standardized surge conditions.
It meets IEC 61000-4-2 ESD immunity up to ±30 kV (contact/air), supports junction temperatures from –55 °C to +175 °C, and exhibits low incremental surge resistance for minimal voltage overshoot during fast transients such as inductive switching or lightning-induced surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 17 V - Maximum reverse stand-off voltage before significant leakage; defines safe operating window for continuous DC bias. |
| VBR @ IT = 1 mA | 18.9–20.9 V - Breakdown onset range; ensures reliable, repeatable avalanche conduction onset across production lots. |
| VC @ IPPM = 811 A (10/1000 μs) | ≤27.6 V - Clamping voltage under standard surge waveform; limits downstream IC stress to safe levels. |
| PPPM | 3000 W - Peak pulse power handling capacity; enables protection against high-energy transients like IEC 61000-4-5 surges. |
| IPPM (10/1000 μs) | 811 A - Maximum non-repetitive surge current capability; determines minimum trace width and PCB layout margin. |
| Junction Temp Range | –55 °C to +175 °C - Extended thermal operating envelope suitable for under-hood automotive and industrial environments. |
| ESD Rating | ±30 kV (IEC 61000-4-2, contact/air) - Full-system ESD resilience without external shielding or filtering stages. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, MSL Level 1 (260 °C peak reflow). Matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102. Bidirectional device - no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked end) | Anode/Cathode terminal (bidirectional) | Not polarized - either terminal serves as anode or cathode depending on transient polarity; symmetric clamping behavior. |
| Anode (unmarked end) | Anode/Cathode terminal (bidirectional) | Electrically identical to cathode terminal; no functional distinction in circuit layout or routing. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns. |
| 3000 W peak pulse power (10/1000 μs) | Supports compliance with IEC 61000-4-5 Level 4 surge immunity on 24 V and 48 V industrial buses. |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes voltage overshoot during surge events, reducing risk of latch-up or gate oxide damage in protected MOSFETs/ICs. |
| MSL Level 1 rating | Allows unlimited floor life and single-reflow processing at 260 °C peak, simplifying SMT manufacturing flow. |
| 30 kV HBM ESD immunity | Eliminates need for secondary ESD protection on board-level interfaces such as RS-485 or CAN bus stubs. |
Applications
| Industrial Sensor Interface | DC Power Rail Protection |
|---|---|
Use Scenario: Protecting analog output lines (4–20 mA) and digital I/O (I²C, SPI) of temperature/pressure sensors in factory automation cabinets exposed to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed directly at connector entry point, clamping induced spikes before they reach precision ADCs or microcontroller GPIOs. Use Value: Prevents sensor calibration drift and firmware lockup caused by >1 kV transients, maintaining system uptime in EN 61000-6-2 environments. |
Use Scenario: Safeguarding 24 V DC input stage of PLC I/O modules subjected to load dump and hot-swap surges in rail transport control systems. IC Role / Device Role / Timing Role: Primary overvoltage clamp parallel to bulk input capacitor, absorbing energy from 10/1000 μs surges exceeding 1 kV. Use Value: Limits rail voltage excursion to <28 V during 811 A transients, preventing regulator shutdown and preserving brown-out immunity. |
| Telecom Line Card | Automotive Body Control Module |
Use Scenario: Surge protection on POTS line interface circuits in VoIP gateways and remote terminal units handling legacy telephone signals. IC Role / Device Role / Timing Role: Bidirectional TVS placed between transformer secondary and codec IC, suppressing lightning-induced common-mode surges. Use Value: Maintains signal integrity below 30 dB THD while surviving repeated 6 kV/3 kA IEC 61000-4-5 tests per GR-1089-CORE. |
Use Scenario: Input protection for LIN bus transceivers and LED driver ICs in door module ECUs exposed to battery disconnect transients and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Clamp device mounted at harness connector, limiting induced voltage on 12 V supply and LIN data lines during load dump events. Use Value: Ensures uninterrupted LIN communication during 120 V/50 ms pulses by holding node voltage ≤27.6 V, avoiding transceiver reset. |
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 | Same SMC package but lower PPPM (600 W); VC = 27.6 V at only 21.2 A (10/1000 μs). | Only suitable for low-energy transients (e.g., ESD-only zones), not for IEC 61000-4-5 surge testing. | Select SMBJ17CA only when system-level surge requirements are limited to IEC 61000-4-2 and peak current remains <25 A. |
| SMCJ17CA | Identical SMC package and electrical specs (VBR, VC, PPPM), but rated for 1500 W (10/1000 μs) - not 3000 W. | Lacks sufficient energy handling for 48 V industrial bus protection requiring full 3000 W compliance. | SMCJ17CA is insufficient for applications demanding 3000 W peak pulse power; verify test waveform and energy budget before substitution. |
Compared with SMBJ17CA and SMCJ17CA, the 3.0C17CA-M3 delivers double the peak pulse power of SMCJ17CA and nearly 5× that of SMBJ17CA - enabling single-device compliance with IEC 61000-4-5 Level 4 on 24–48 V rails without parallel stacking.

FAQ
What is the maximum clamping voltage of the 3.0C17CA-M3 under a 10/1000 µs surge?
The 3.0C17CA-M3 clamps to a maximum of 27.6 V when subjected to its rated peak pulse current of 811 A with a 10/1000 µs waveform. This value is guaranteed across temperature and process variation per Vishay Document 98266, ensuring predictable overvoltage limiting for downstream components.
Is the 3.0C17CA-M3 suitable for automotive applications requiring AEC-Q200 qualification?
The 3.0C17CA-M3 is not AEC-Q200 qualified. While it operates from –55 °C to +175 °C and meets MSL Level 1, Vishay does not list it in their AEC-Q200-certified portfolio. For automotive body control modules, use only AEC-Q200-qualified variants such as the AUTOMOTIVE-grade 3.0C17CAHM3 if specified in design requirements.
Does the 3.0C17CA-M3 have polarity markings on the SMC package?
No - the 3.0C17CA-M3 is a bidirectional TVS diode and carries no polarity marking on the SMC (DO-214AB) package. Both terminals are functionally identical; orientation during placement has no electrical impact, simplifying automated assembly and reducing misplacement risk.
What is the thermal resistance junction-to-ambient (RthJA) for the 3.0C17CA-M3?
The 3.0C17CA-M3 has a typical RthJA of 90 °C/W when mounted on a standard FR4 PCB with 2 oz. copper and JEDEC 51-2A footprint. This value assumes natural convection cooling and informs thermal derating calculations for sustained surge duty cycles or elevated ambient temperatures.
Can the 3.0C17CA-M3 replace the 3.0C15CA-M3 in an existing design?
Yes - the 3.0C17CA-M3 can replace the 3.0C15CA-M3 if the higher VBR (18.9–20.9 V vs. 16.7–18.5 V) and slightly higher VC (27.6 V vs. 24.4 V) align with system margin requirements. Verify that the increased standoff voltage does not compromise normal-mode noise rejection or trigger false overvoltage detection in the protected circuit.
