Semtech Expands RClamp Platform to Safeguard Telecom and Industrial Applications from Surge and Electrostatic Discharge (ESD) Threats

Semtech’s RClamp2594N provides superior protection for data-line interfaces from dangerous ESD and surge threats

CAMARILLO, Calif., March 28, 2018 -- Semtech Corporation (Nasdaq: SMTC), a leading supplier of high performance analog and mixed-signal semiconductors and advanced algorithms, today announced the newest member of its RClamp® low capacitance surge protection platform. This new four-line transient voltage suppressor (TVS) array offers high-surge, low-capacitance transient protection in an easy-to-route device footprint. Optimized for outstanding protection of telecom and industrial data interfaces from dangerous transient voltage threats, the device also minimizes capacitive loading on high-speed interfaces.

Targeted at telecom and industrial applications residing in harsh electrical environments, Semtech’s new RClamp2594N array offers an impressive 35A (8x20µs waveform) of surge immunity and achieves a ±30kV contact/±30kV air ESD discharge immunity rating.  This product significantly exceeds industry standard electromagnetic compatibility (EMC) requirements, delivering optimal clamping voltage performance while presenting a very low 2.1pF line-to-line capacitance.

“Today’s telecommunications and industrial systems demand higher levels of surge and ESD protection,” said Tamir Reshef, Product Marketing Director for the Industrial and Telecom division of Semtech’s Protection Products Group. “Semtech continues to lead the way in protecting high-speed interfaces from harsh electrical transient events. The RClamp2594N provides excellent transient protection on high-speed data communication interfaces in the telecom infrastructure.”
