Semtech unveils Split-pad TVS circuit device

BANGALORE: A new circuit protection device with split-pad transient voltage suppression (TVS) architecture has debuted as part of the Semtech line.

The company said it has unveiled its new Rclamp0524S circuit protection product, designed to protect Power Over Ethernet (POE) interfaces from electrical surges and transients.

The four-line Rclamp0524S incorporates two surge-rated, low capacitance TVS diode arrays to clamp rise-time transient voltage spikes to a safe threshold, it added.

The device comes as part of a RailClamp platform device that safeguards submicron CMOS ICs from electrical surges including electrostatic discharge (ESD), cable discharge events (CDE), electrical fast transients (EFT) and residual lightning surges.

The RClamp0524S sports split-pad TVS architecture making it a better alternative than discrete solutions. It is also being expected that device would be succesful in providing critical savings in terms of BOM costs and board space, as well as offering all of the low clamping, low capacitance and durability advantages of Semtech’s solid-state silicon-avalanche technology.

Features include a flow-through layout, suitable for PCB trace routing and mitigating parasitics in applications such as Wireless Access Points, VoIP Telephony and Digital Surveillance Cameras. According to the company, the RClamp0524S can be located on the PCB or inside the RJ-45 connector.
