Targeted for industrial, datacenter and telecommunications applications, the Semtech Protection RClamp0822B platform delivers high-performance electrostatic discharge (ESD) and surge protection

CAMARILLO, Calif., May 31, 2023 – Semtech Corporation (Nasdaq: SMTC), a high-performance semiconductor, IoT systems, and Cloud connectivity service provider, today announced the latest addition to its Transient Voltage Suppressors (TVS) product portfolio, the RClamp0822B. The RClamp® platform is a purpose-built, versatile circuit protection platform for safeguarding high speed data interfaces across a broad spectrum of circuit interfaces in industrial, datacenter and telecommunication applications. The 2-line, 8V RClamp0822B offers high-performance electrostatic discharge (ESD) and surge protection in an industry standard three lead SC-75 package. 

Semtech Protection products safeguard the industry’s leading electronic systems and circuits from potentially harmful electrostatic discharge and surge threats. Semtech’s TVS product suite keeps products and the people they serve safe. With more than 50 years industry experience, customers building and bringing to market devices with Semtech Protection know that their products have been tested to the specifications for the latest silicon transceivers and interfaces regardless of end user application. 

Presenting a very-low sub 1 picofarad of loading capacitance, the RClamp0822B is ideally suited to safeguard high-speed data lines that are increasingly vulnerable to electrical transient threats. The RClamp0822B also provides a robust surge immunity, while it is packaged in a small but user-friendly SC-75 package. This package affords circuit designers flexibility in their PCB layout designs as this package includes a pair of diodes for two signal lines. 

“The easiest and most sensible path to ensuring reliable system operation while ensuring signal quality in power quality-challenged environments is prevention. Organizations and their teams must plan and build safeguards at vulnerable points in a system to mitigate damage caused by surges and voltage spikes. It’s vitally important that designs address high performance protection across many different circuit interfaces,” said Tamir Reshef, product marketing vice president for Semtech’s Advanced Protection and Sensing Products Group. “The expense to install these circuit protection solutions is nominal compared to the potentially damaging costs if no safeguards are installed and the unthinkable happens. The RClamp0822B is an extremely flexible device. It gives hardware engineers a single-package high performance protection solution that is well suited for broad range of industrial designs.”
