SEMTECH RCLAMP0854P.TCT

RailClamp is a low capacitance TVS array designed to protect high speed data interfaces. This series has been specifically designed to protect sensitive components 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 RClamp0854P 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 5.5 volts. Loading capacitance on these lines is <0.1ρF for maximum signal integrity. An integrated 5.5 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. The RClamp0854P is in a 6-pin, RoHS compliant, SLP1616P6 package. It measures 1.6×1.6x 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).
