SEMTECH RCLAMP1624T.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 RClamp1624T is specifically designed to protect portable devices that utilize a uUSB port. The unique design of this device features low capacitance TVS diodes for protection of the USB data (DP, DM) and USB ID pins operating up to 5 volts. Loading capacitance on these lines is < 1pF for maximum signal integrity. An integrated L2 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 RClamp1624T is in a 6- pin SLP1710P4T package. It measures 1.7 × 1.0 × 0.40mm. The leads are spaced at a pitch of 0.4mm and are finished with lead- free NiPdAu. They may be used to meet the ESD immunity requirements of IEC 61000- 4- 2.
