1 www.semtech.com RClamp0502A Low Capacitance TVS Array PROTECTION PRODUCTS - RailClamp ®®®®® Description Features Circuit Diagram Schematic & PIN Configuration Revision 06/28/2008 The RailClamp® series consists of ultra low capacitance TVS arrays designed to protect high speed data inter- faces. 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). They are designed for use in applications where board space is at a premium. Each device requires less than 2.9mm 2 of PCB area and will protect two high speed data lines. The monolithic design incorporates surge rated, low capacitance steering diodes and a TVS diode in a single package. Each line has a typical capacitance of 0.9pF to ground and 0.3pF between lines. The capacitance of each line is well matched for consistant signal balance. Signal integrity is further preserved with the flow through design. A connection to the TVS is provided for protec- tion of external voltage busses, such as those found in USB applications. This device is optimized for ESD protection of portable electronics. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact discharge). The RClamp0502A is in a 6-pin, RoHS/WEEE compli- ant, SC-89 (SOT-666) package. It measures 1.6 x 1.6 x 0.6mm. The leads are finished with lead-free matte tin. The small package makes it ideal for use in por- table electronics such as cell phones, laptops, and digital still cameras.
