RClamp0854P RailClamp Low Capacitance TVS Array PROTECTION PRODUCTS - RailClamp Features Description RailClamp is a low capacitance TVS array designed to Transient protection for high-speed data lines 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 (1.6 x 1.6mm) saves board space discharge), CDE (Cable Discharge Events), and EFT Protects USB DP, DM, and ID Pin operating up to (electrical fast transients). 5.5V The RClamp0854P is specifically designed to protect Protects USB VBus operating up to 5.5V portable devices that utilize the USB port for battery Low capacitance (<1pF) on DP, DM, and ID Pins charging. The unique design of this device features low 2.0GHz2.0GHz No insertion loss to 2.0GHz2.0GHz2.0GHz capacitance TVS diodes for protection of the USB data Low leakage current (DP, DM) and USB ID (accessory detect) pins operating Low clamping voltage up to 5.5 volts. Loading capacitance on these lines is Large ground pad for increased ESD performance <0.1pF for maximum signal integrity. An integrated 5.5 Solid-state silicon-avalanche technology volt TVS diode is used for protection of the USB voltage bus. This ensures the device will remain in a Mechanical Characteristics high-impedance state during normal USB operation or SLP1616P6 6L package when the battery is being charged. RoHS/WEEE Compliant The RClamp0854P is in a 6-pin, RoHS compliant, Nominal Dimensions: 1.6 x 1.6 x 0.60 mm SLP1616P6 package. It measures 1.6 x 1.6 x Lead Finish: NiPdAu 0.60mm. The leads are spaced at a pitch of 0.5mm Molding compound flammability rating: UL 94V-0 and are finished with lead-free NiPdAu. They may be used to meet the ESD immunity requirements of IEC Marking : Marking code + two character date code 61000-4-2, Level 4 (15kV air, 8kV contact discharge).
