RClamp3624T RailClamp ESD Protection for uUSB Interfaces PROTECTION PRODUCTS - RailClamp Features Description Transient protection for high-speed data lines to RailClamp TVS arrays are ultra low capacitance ESD IEC 61000-4-2 (ESD) 18kV (air), 12kV (contact) protection devices designed to protect high speed data IEC 61000-4-4 (EFT) 40A (5/50ns) interfaces. This series has been specifically designed Array of surge rated diodes with internal TVS Diode to protect sensitive components which are connected to data and transmission lines from overvoltage Small package saves board space caused by ESD (electrostatic discharge), CDE (Cable Flow-Through design for easy layout Discharge Events), and EFT (electrical fast transients). Protects USB DP, DM, and ID Pin operating to 5V The RClamp 3624T is specifically designed to protect Protects USB VBus operating up to 28V portable devices that utilize a uUSB port. The unique Low capacitance (<1pF) on DP, DM, and ID Pins design of this device features low capacitance TVS No insertion loss to 2.0GHz2.0GHz2.0GHz2.0GHz2.0GHz diodes for protection of the USB data (DP, DM) and Low leakage current USB ID pins operating up to 5 volts. Loading capaci- Low clamping voltage tance on these lines is <1pF for maximum signal Solid-state silicon-avalanche technology integrity. An integrated 28 volt TVS diode is used for protection of the USB voltage bus. This ensures the Mechanical Characteristics device will remain in a high-impedance state during SLP1710P4T 6L package normal USB operation or when the battery is being Pb-Free, Halogen Free, RoHS/WEEE Compliant charged. Leakage current of the VBus protection is <250nA when operating at 28 volts. Nominal Dimensions: 1.7 x 1.0 x 0.40 mm Lead Finish: NiPdAu The RClamp3624T is in a 6-pin SLP1710P4T package. It measures 1.7 x 1.0 x 0.40mm. The leads are Molding compound flammability rating: UL 94V-0 spaced at a pitch of 0.4mm and are finished with lead- Marking : Marking code free NiPdAu. They may be used to meet the ESD Packaging : Tape and Reel immunity requirements of IEC 61000-4-2.
