1 www.semtech.com PRELIMINARYPROTECTION PRODUCTS - RailClamp®®®®® RClamp0524J Ultra Low Capacitance TVS Arrays Description Features Dimensions Circuit Diagram Revision 02/05/2008 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 TM0524J 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, Level 4 (±15kV air, ±8kV contact discharge). Each device is designed to protect four lines (two differential pairs). The RClamp0524J is in a 8-pin, RoHS/WEEE compliant, The leads are spaced at a pitch of 0.5mm and are fin- ished with lead-free NiPdAu. They are designed for easy PCB layout by allowing the traces to run straight through the device. The combination of small size, low capaci- tance, and high level of ESD protection makes them a flexible solution for applications such as HDMI, DisplayPort TM, MDDI, and eSATA interfaces.
