1 / 10 page  1 www.semtech.com RClamp1654P RailClamp®®®®® Low Capacitance TVS Array PROTECTION PRODUCTS - RailClamp® ® ® ® ® Description Features Circuit Diagram PIN Configuration Revision 11/07/2008 RailClamp® is a low capacitance TVS array designed to protect high speed data interfaces. This series has been specifically designed to protect sensitive compo- nents which are connected to data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (Cable Discharge Events), and EFT (electrical fast transients). The RClamp1654P is specifically designed to protect portable devices that utilize the USB port for battery charging. The unique design of this device features low capacitance TVS diodes for protection of the USB data (DP, DM) and USB ID (accessory detect) pins operating up to 5 volts. Loading capacitance on these lines is <1pF for maximum signal integrity. An integrated 12 volt TVS diode is used for protection of the USB voltage bus. This ensures the device will remain in a high-impedance state during normal USB operation or when the battery is being charged. Leakage current of the VBus protection is <50nA when operating at 12 volts. The RClamp1654P is in a 6-pin, RoHS compliant, SLP1616P6 package. It measures 1.6 x 1.6 x 0.60mm. The leads are spaced at a pitch of 0.5mm and are finished with lead-free NiPdAu. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (15kV air, 8kV contact discharge). Applications Mechanical Characteristics USB 2.0 USB OTG Transient protection for high-speed data lines to IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact) IEC 61000-4-4 (EFT) 40A (5/50ns) Array of surge rated diodes with internal TVS Diode Small package (1.6 x 1.6mm) saves board space Protects USB DP, DM, and ID Pin operating up to 5.5V Protects USB VBus operating up to 12V Low capacitance (<1pF) on DP, DM, and ID Pins Minimal insertion loss to 2.0GHz 2.0GHz 2.0GHz 2.0GHz 2.0GHz Low leakage current Low clamping voltage Large ground pad for increased ESD performance Solid-state silicon-avalanche technology SLP1616P6 6L package RoHS/WEEE Compliant Nominal Dimensions: 1.6 x 1.6 x 0.60 mm Lead Finish: NiPdAu Molding compound flammability rating: UL 94V-0 Marking : Marking code + two character date code Packaging : Tape and Reel SLP1616P6 (Top View) 1 Gnd 2 3 6 5 4 USB ID DM DP NC VBus NC 12 3 GND 6 5.5V 12V |
