RClamp1224S Low Capacitance TVS for ADSL Interfaces PROTECTION PRODUCTS - RailClamp Features Description RailClamp TVS arrays are ultra low capacitance ESD Transient protection for high-speed data lines to protection devices designed to protect high speed IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) data interfaces. This series has been specifically IEC 61000-4-4 (EFT) 40A (5/50ns) IEC 61000-4-5 (Lightning) , 15A (8/20 s) designed to protect sensitive components which are connected to high-speed data and transmission lines Optimized for easy PCB layout from overvoltage caused by ESD (electrostatic dis- Low capacitance: 3pF3pF3pF3pF3pF charge), CDE (Cable Discharge Events), and EFT Operating voltage: 12V (electrical fast transients). Low clamping voltage Small Package saves board space These devices integrate low capacitance, surge-rated compensation diodes with high power transient voltage Solid-state technology suppressors (TVS). The capacitance of the device is Mechanical Characteristics limited to 3pF maximum to ensure correct signal transmission on high-speed lines. JEDEC SOT-23 6L package The RClamp 1224S is in a 6-pin SOT-23 package. The Pb-Free, Halogen Free, RoHS/WEEE Compliant leads are finished with lead-free matte tin. They are Nominal Dimensions: 2.9 x 2.8mm particularly well suited for applications where board Molding compound flammability rating: UL 94V-0 space is at a premium. The RClamp1224S may be Marking: Marking Code + Date Code used to protect xDSL interfaces, multi-protocol serial Packaging: Tape and Reel transceivers, portable electronics, and wireless sys- tems.
