RClamp0544M RailClamp ESD Protection for HDMI Interfaces 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) 18kV (air), 12kV (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 0544M has a typical capacitance of only Low capacitance: 0.3pF typical (I/O to I/O) 0.30pF. This means it can be used on circuits operating Low clamping voltage in excess of 2GHz without signal attenuation. They may Low operating voltage: 5.0V be used to meet the ESD immunity requirements of IEC Solid-state silicon-avalanche technology 61000-4-2, Level 4 (15kV air, 8kV contact discharge). Mechanical Characteristics These devices are in a MSOP 10L package and feature a lead-free, matte tin finish. They are compatible with both JEDEC MSOP 10L package lead free and SnPb assembly techniques. They are de- Molding compound flammability rating: UL 94V-0 signed for easy PCB layout by allowing the traces to run Marking : Marking code and date code straight through the device. The combination of small Packaging : Tape and Reel per EIA 481 size, low capacitance, and high level of ESD protection Lead Finish: Matte Tin makes them a flexible solution for protecting high-speed RoHS/WEEE Compliant HDMI and DVI video interfaces.
