Semtech has introduced the RClamp0524S, a new circuit protection device with split-pad transient voltage suppression (TVS) architecture. It is designed to protect Power Over Ethernet (POE) interfaces from electrical surges and transients.

The four-line RClamp0524S’ design incorporates two surge-rated, low capacitance TVS diode arrays to clamp rise-time transient voltage spikes to a safe threshold.

Semtech claims that this RailClamp platform device 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’ integrated diode arrays feature flow-through layout, suitable for PCB trace routing and mitigating parasitics in applications such as Wireless Access Points, VoIP Telephony and Digital Surveillance Cameras.

The RClamp0524S can be located on the PCB or inside the RJ-45 connector. It is ROHS & WEEE compliant and packaged in a SOT-23 6L package.

Rick Hansen, director of product marketing for protection products at Semtech, said: “The split-pad TVS architecture of the RClamp0524S makes it a better alternative than discrete solutions, providing critical savings in terms of BOM costs and board space while also offering all of the low clamping, low capacitance and durability advantages of Semtech’s solid-state silicon-avalanche technology.”
