SEMTECH RCLAMP0582B.TCT

The RClamp 0582B transient voltage suppressor is specifically designed to protect sensitive components which are connected to high-speed data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (cable discharge events), and EFT (electrical fast transients). The RClamp 0582B features high peak pulse current capability (I_PP = 15A, t >= 8/20μs) for use in applications that require high surge immunity testing. It has a maximum capacitance of only 1.2pF (pin 1 or 2 to pin3). They may be used to meet the ESD immunity requirements of IEC 61000 - 4 - 2 (±30kV air, ±25kV contact discharge). Each device can be configured to protect 1 bidirectional line or two unidirectional lines. These devices are in a small SC - 75 (SOT - 523) package and feature a lead - free, matte tin finish. They are compatible with both lead free and SnPb assembly techniques. The combination of small size, low capacitance, and high level of surge protection makes them a flexible solution for protection of USB 2.0, LVDS, and video interfaces.
