RClamp1654P 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 RClamp1654P is specifically designed to protect Protects USB VBus operating up to 12V 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 Minimal 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 volts. Loading capacitance on these lines is Large ground pad for increased ESD performance <1pF for maximum signal integrity. An integrated 12 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. Leakage current of RoHS/WEEE Compliant the VBus protection is <50nA when operating at 12 Nominal Dimensions: 1.6 x 1.6 x 0.60 mm volts. Lead Finish: NiPdAu The RClamp1654P is in a 6-pin, RoHS compliant, Molding compound flammability rating: UL 94V-0 SLP1616P6 package. It measures 1.6 x 1.6 x 0.60mm. The leads are spaced at a pitch of 0.5mm Marking : Marking code + two character date code and are finished with lead-free NiPdAu. They may be Packaging : Tape and Reel used to meet the ESD immunity requirements of IEC Applications 61000-4-2, Level 4 (15kV air, 8kV contact discharge).
