ESD, EFT and EOS Protection for Industrial Interfaces

Semtech Corporation announced the µClamp2417P, a 7-line surge-rated, 24V transient protection array for broad use in safeguarding industrial interfaces against transient voltage threats. The µClamp2417P offers a 10A (8x20µs waveform) surge immunity level in a small 2.6 x 2.6mm QFN package and is designed for safeguarding industrial data interfaces from electrical transient threats including electrostatic discharge (ESD), electrical fast transients (EFT), electrical overstress (EOS) and lightning surge transients.

The 7-line μClamp2417P, with its excellent voltage clamping characteristics, delivers efficient transient protection for multi-line industrial data ports. The part’s high surge immunity makes it ideal for protecting ports from induced lightning threats, and the uClamp2417P also achieves a high level of immunity against fast rise-time ESD transients, allowing customers to achieve compliance in excess of the industry’s most stringent ESD immunity standards (IEC 61000-4-2).

“With the explosion of IoT and emerging end nodes in industrial applications, an increasing number of industrial data circuits are exposed to highly destructive electrical transient threats,” said Rick Hansen, Product Marketing Director for Semtech’s Protection Product Group. “The μClamp2417P offers circuit designers a robust ESD and surge protection solution to safeguard data ports that operate in a harsh electrical environment.”

Key Features of the μClamp2417P: Transient protection for high-speed data lines to: IEC 61000-4-2 (ESD) ±25kV (air), ±17kV (contact); IEC 61000-4-4 (EFT) 40A (5/50ns); IEC 61000-4-5 (Lightning) 100A (8/20μs); 24V working voltage protection; High surge capability: 10A (tp=8/20μs); Protects 7 bidirectional lines, can also be used to protect 8 I/O lines; Low capacitance (<50 pF line-to-line); Small 2.6 x 2.6 x 0.5mm package; and Pb Free and RoHS/WEEE compliant.

The μClamp2417P (order code: μClamp2417P.TCT) is available immediately in production quantities and is priced at $0.52 each in 10,000-piece lots.
