1 www.semtech.com PRELIMINARYPROTECTION PRODUCTS - RailClamp®®®®® RClamp0544T Ultra Low Capacitance TVS Arrays Description Features Dimensions Circuit Diagram Revision 2/25/2011 RailClamps® are ultra low capacitance TVS arrays 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). The RClamp ®0544T has a typical capacitance of only 0.30pF between I/O pins. This allows it to be used on circuits operating in excess of 3GHz without signal attenuation. They may be used to meet the ESD immunity requirements of IEC 61000-4-2. Each device is designed to protect four lines (two differential pairs). The RClamp0544T is in an 8-pin SLP2010P8T package. It measures 2.0 x 1.0 x 0.4mm. The leads are spaced at a pitch of 0.4mm and are finished with lead-free NiPdAu. They are designed for easy PCB layout by allowing the traces to run straight through the device. The combina- tion of small size, low capacitance, and high level of ESD protection makes them a flexible solution for applica- tions such as mini HDMI, MDDI, USB, and eSATA inter- faces.
