Semtech’s new ultra-low capacitance TVS device offers industry leading ESD protection for high speed data lines
Semtech Corporation 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.
