24V transient protection array from Semtech defends against 10A surge

7-line surge-rated, 24V transient protection array µClamp2417P from Semtech protects industrial interfaces against voltage transients. 2.6 x 2.6mm QFN packaged µClamp2417P can defend the circuit against a 10A (8x20µs waveform) surge making it suitable for industrial data interfaces from electrical transient threats including electrostatic discharge (ESD), electrical fast transients (EFT) and lightning surge transients.

The 7-line µClamp2417P is praised for its best voltage clamping characteristics and efficient transient protection for multi-line industrial data ports. High surge immune µClamp2417P is suggested as 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 Specifications/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
Pb Free and RoHS/WEEE compliant

Price and Availability: The µClamp2417P (order code: µClamp2417P.TCT) is available immediately in production quantities and is priced at $0.52 each in 10,000-piece lots. For more info visit www.semtech.com
