SEMTECH RCLAMP0502BATCT

RailClamp TVS diodes are specifcally 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 0502BA has a typical capacitance of only 0.50pF (pin1 to 2). This means it can be used on circuits operating in excess of 3GHz with minimal signal attenuation. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±18kV air, ±12kv contact discharge). Each device can be confgured 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 fnish. They are compatible with both lead free and SnPb assembly techniques. They are designed for use in applications where board space is at a premium. The combination of small size, low capacitance, and high level of ESD protection makes them a fexible solution for applications such as HDMI, MDDI, antenna circuits, Automatic Test Equipment, USB 2.0/3.0, and Infniband circuits.
