Semtech Introduces New RClamp® Device for Safeguarding USB Type-C Interfaces

Semtech Corporation (Nasdaq: SMTC), a leading supplier of high performance analog and mixed-signal semiconductors and advanced algorithms, today announced the latest addition to its RClamp® platform. The RClamp3371ZC exceeds industry immunity standards for electrostatic discharge (ESD) protection robustness while only presenting 250 femtofarads of maximum loading capacitance. Engineered as a low clamping, ultra-low capacitance transient voltage suppression (TVS) device, the RClamp3371ZC is an ideal solution for safeguarding high speed interfaces, such as USB Type-C, from common ESD threats.

As high-speed transceiver ICs implemented on ever-shrinking silicon geometries become increasingly sensitive to transient voltage spikes, the need for high performance protection circuitry is becoming even more critical. These ICs require ultra-low clamping voltage protection while also presenting a minimal loading capacitance. Based on Semtech’s FemtoClamp™ technology, the RClamp3371ZC utilizes an advanced ultra-low capacitance TVS silicon process for achieving the highest performance ESD protection for high speed data communication channels. RClamp3371ZC is housed in a very small 0201 package giving board designers key space savings and a high degree of layout flexibility.

"USB Type-C interfaces are rapidly becoming the data transfer standard for communications and handheld devices,” said Tee Lim, Product Marketing Director for Semtech’s Protection Products Group. "Semtech’s RClamp3371ZC gives the hardware design community a highly differentiated protection device optimized for safeguarding these important high speed USB data ports.”
