RClamp0514M RailClamp Low Capacitance TVS Diode Array PROTECTION PRODUCTS PRELIMINARY PROTECTION PRODUCTS - RailClamp Features Description RailClamps are ultra low capacitance TVS arrays ESD protection for high-speed data lines to designed to protect high speed data interfaces. This IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) series has been specifically designed to protect sensi- IEC 61000-4-5 (Lightning) 5A (8/20s) tive components which are connected to high-speed IEC 61000-4-4 (EFT) 40A (5/50ns) data and transmission lines from overvoltage caused Array of surge rated diodes with internal TVS Diode by ESD (electrostatic discharge), CDE (Cable Discharge Small package saves board space Events), and EFT (electrical fast transients). Protects four I/O lines and one Vcc line TM The RClamp 0514M has a typical capacitance of only Low capacitance: 0.7pF typical (Line-to-Line) 0.70pF (I/O to I/O). This means it can be used on Low clamping voltage circuits operating in excess of 2GHz without signal Low operating voltage: 5.0V attenuation. They may be used to meet the ESD Solid-state silicon-avalanche technology immunity requirements of IEC 61000-4-2, Level 4 (15kV air, 8kV contact discharge). Mechanical Characteristics These devices are in a MSOP 10L package and feature a JEDEC MSOP 10L package lead-free, matte tin finish. They are compatible with both Molding compound flammability rating: UL 94V-0 lead free and SnPb assembly techniques. They are de- Marking : Marking code and date code signed for easy PCB layout by allowing the traces to run Packaging : Tape and Reel per EIA 481 straight through the device. The combination of small Lead Finish: Matte Tin size, low capacitance, and high level of ESD protection RoHS/WEEE Compliant makes them a flexible solution for protecting high-speed HDMI and DVI video interfaces.
