Semtech’s RClamp1255P Protects USB 2.0 Data Lines from ESD Transients and VBUS from Surges, Expanding the Company’s Robust Mobile Protection Platform

CAMARILLO, Calif.--(BUSINESS WIRE)-- Semtech Corp. (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today 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 highly differentiated process technologies that achieve the industry’s lowest 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.”
