Semtech Expands its Industrial and Telecoms TVS Array Offering

Semtech Corporation announced the latest addition to its RClamp® platform. The four-line, 5V RClamp0504FB offers robust electrostatic discharge (ESD) protection and superior surge immunity in an industry standard six lead SC-70 package. This transient voltage suppression (TVS) array offers extensive interface protection versatility with its differentiated performance and small form factor enabling use in data ports for industrial, Internet of Things (IoT) and telecommunication applications.

Exceeding industry standards for ESD immunity, the RClamp0504FB offers a 28A Ipp surge rating and is housed in a compact SC-70 package. This footprint presents hardware designers PCB space savings and the familiarity of an established multi-line package. The RClamp0504FB offers an extremely low typical capacitance of 1.1pF, making the device well suited for use in high speed differential interfaces.

"As silicon transceivers continue to scale to smaller geometries, the vulnerability of present day microelectronic devices to overvoltage and surge threats is among the highest it has been in the industry's history," said Timothy Puls, Product Marketing Director for Semtech's Protection Products Group. "The RClamp0504FB is an extremely flexible device that gives hardware engineers an outstanding, versatile solution for protecting a broad range of data interfaces from some of the harshest ESD and surge threats."
