TVS Protection Device for USB 2.0 Interfaces on Portable Devices

Semtech Corp. announced the RClamp1255P, a high-performance, low capacitance transient voltage suppression (TVS) device. The RClamp1255P is a highly integrated device that replaces multiple discrete components while providing complete VBUS surge protection, and ESD protection for USB data lines and ID line. Built on Semtech’s process technologies that achieve low clamping voltages, the RClamp1255P delivers optimal transient protection and is housed in a 2.0 x 1.8 mm package with a height of only 0.57mm. The small size, low capacitance, and high level of surge and ESD protection makes the RClamp1255P an ideal solution for protecting USB interfaces in mobile phones, laptops and portable electronics.

“With increasing consumption of 4G data, consumers demand reliable solutions that enable them to stay connected to mobile networks. Robust ESD protection is more important to portable electronics manufacturers than ever before,” said Rick Hansen, Product Marketing Director for Semtech’s Protection Products. “The RClamp1255P expands Semtech’s growing portable product family and offers fully integrated ESD and surge protection for USB 2.0 ports used on portable devices in a single easy to use package.”

Key Features of the RClamp1255P: Transient protection for USB VBUS to: IEC 61000-4-2 (ESD) ±30kV (air), ±30kV (contact); IEC 61000-4-4 (EFT) 40A (5/50ns); IEC 61000-4-5 (Lightning) 100A (8/20µs); Protects USB VBUS operating up to 12V;ESD protection for high-speed USB 2.0 data lines to: IEC 61000-4-2 (ESD) ±15 (air), ±10kV (contact);Protects USB D+, D- and ID pins operating up to +/- 4V;Low capacitance <0.5pF on D+, D- and ID pins; Small 6-lead 2.0mm x 1.8mm package with nominal height of 0.57 mm; and Pb Free and RoHS/WEEE compliant. The RClamp1255P (order code: RClamp1255P.TGT) is available immediately in production quantities and is priced at $0.33 each in 3,000-piece lots.
