SEMTECH RCLAMP1224S.TCT

RailClamp TVS arrays are ultra low capacitance ESD protection devices designed to protect high speed data interfaces. This series has been specifically designed to protect sensitive components which are connected to high- speed data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and EFT (electrical fast transients). These devices integrate low capacitance, surge- rated compensation diodes with high power transient voltage suppressors (TVS). The capacitance of the device is limited to 3pF maximum to ensure correct signal transmission on high- speed lines. The RClamp1224S is in a 6- pin SOT- 23 package. The leads are finished with lead- free matte tin. They are particularly well suited for applications where board space is at a premium. The RClamp1224S may be used to protect xDSL interfaces, multi- protocol serial transceivers, portable electronics, and wireless systems.
