RClamp1624T RailClamp ESD Protection for uUSB Interfaces PROTECTION PRODUCTS - RailClamp Features Description Transient protection for high-speed data lines to RailClamp is a low capacitance TVS array designed to IEC 61000-4-2 (ESD) 18kV (air), 12kV (contact) protect high speed data interfaces. This series has IEC 61000-4-4 (EFT) 40A (5/50ns) been specifically designed to protect sensitive compo- Array of surge rated diodes with internal TVS Diode nents which are connected to data and transmission lines from overvoltage caused by ESD (electrostatic Small package saves board space discharge), CDE (Cable Discharge Events), and EFT Protects USB DP, DM, and ID Pins to 5V (electrical fast transients). Protects USB VBus operating up to 12V The RClamp1624T is specifically designed to protect Low capacitance (<1pF) on DP, DM, and ID Pins portable devices that utilize a uUSB port. The unique No insertion loss to 2.0GHz2.0GHz2.0GHz 2.0GHz2.0GHz design of this device features low capacitance TVS Low leakage current diodes for protection of the USB data (DP, DM) and Low clamping voltage USB ID pins operating up to 5 volts. Loading capaci- Innovative flow-through design allows easy pcb tance on these lines is <1pF for maximum signal layout integrity. An integrated 12 volt TVS diode is used for Solid-state silicon-avalanche technology protection of the USB voltage bus. This ensures the Mechanical Characteristics device will remain in a high-impedance state during normal USB operation or when the battery is being SLP1710P4T 6L package charged. Leakage current of the VBus protection is Pb-Free, Halogen Free, RoHS/WEEE Compliant <50nA when operating at 12 volts. Nominal Dimensions: 1.7 x 1.0 x 0.40 mm The RClamp1624T is in a 6-pin SLP1710P4T package. Lead Finish: NiPdAu 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 + date code free NiPdAu. They may be used to meet the ESD Packaging : Tape and Reel immunity requirements of IEC 61000-4-2.
