RClamp2504P & RClamp3304P RailClamp 2.5V & 3.3V TVS Arrays PROTECTION PRODUCTS - RailClamp Features Description Transient protection for high-speed data lines to RailClamp is a low capacitance TVS array designed to protect high speed data interfaces. This series has been IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) specifically designed to protect sensitive components IEC 61000-4-4 (EFT) 40A (5/50ns) which are connected to data and transmission lines from Array of surge rated diodes with internal TVS Diode overvoltage caused by ESD (electrostatic discharge), CDE Small package saves board space (Cable Discharge Events), and EFT (electrical fast tran- Protects up to four I/O lines sients). Low capacitance (<0.8pF) for high-speed interfaces The monolithic design incorporates surge rated, low Minimal insertion loss to 3.0GHz3.0GHz3.0GHz3.0GHz3.0GHz capacitance steering diodes and a TVS diode in a single Low operating voltage: 2.5V and 3.3V package. Each line has a maximum capacitance of Low leakage current and clamping voltage < 0.8pF to ground. The capacitance of each line is well Solid-state silicon-avalanche technology matched for consistant signal balance. This device is optimized for ESD protection of portable electronics. It Mechanical Characteristics may be used to meet the ESD immunity requirements SLP1616P6 package of IEC 61000-4-2, Level 4 (15kV air, 8kV contact RoHS/WEEE Compliant discharge). Nominal Dimensions: 1.6 x 1.6 x 0.58 mm TM TM The RClamp 2504P and RClamp 3304P are con- Lead Finish: NiPdAu structed using Semtechs proprietary EPD process Molding compound flammability rating: UL 94V-0 technology. The EPD process provides low standoff Marking: Marking Code + Date Code voltages with significant reductions in leakage current Packaging: Tape and Reel per EIA 481 and capacitance over silicon-avalanche diode pro- cesses. They feature a true operating voltage of 2.5 Applications volts and 3.3 volts for superior protection. Multi Media Card (MMC) Interfaces These devices are in a 6-pin, RoHS/WEEE compliant, SATA Interfaces SLP1616P6 package measuring 1.6 x 1.6 x 0.58mm. SD Card Interfaces The leads are spaced at a pitch of 0.5mm and are SIM Ports finished with lead-free NiPdAu.
