RClamp0504F RailClamp Low Capacitance TVS Array PROTECTION PRODUCTS - RailClamp Features Description Transient protection for high-speed data lines to RailClamps are surge rated diode arrays designed to protect high speed data interfaces. This series has IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) been specifically designed to protect sensitive compo- IEC 61000-4-4 (EFT) 40A (5/50ns) nents which are connected to data and transmission Array of surge rated diodes with internal TVS Diode lines from overvoltage caused by ESD (electrostatic Small package (2.4 x 2.2mm) saves board space discharge), CDE (Cable Discharge Events), and EFT Protects up to four I/O lines & power line (electrical fast transients). Low capacitance (<3pF) for high-speed interfaces The unique design incorporates surge rated, low No insertion loss to 2.0GHz2.0GHz2.0GHz2.0GHz2.0GHz capacitance steering diodes and a TVS diode in a Low leakage current and clamping voltage single package. During transient conditions, the Low operating voltage: 5.0V steering diodes direct the transient to either the Solid-state silicon-avalanche technology positive side of the power supply line or to ground. The internal TVS diode prevents over-voltage on the power Mechanical Characteristics line, protecting any downstream components. EIAJ SC-70 6L package The low capacitance array configuration allows the user Lead Finish: Matte Tin to protect four high-speed data or transmission lines. RoHS/WEEE Compliant The low inductance construction minimizes voltage Molding compound flammability rating: UL 94V-0 overshoot during high current surges. This device is Marking : F54 optimized for ESD protection of portable electronics. Packaging : Tape and Reel per EIA 481 They may be used to meet the ESD immunity require- ments of IEC 61000-4-2, Level 4 (15kV air, 8kV Applications contact discharge).
