1 / 6 page  1 www.semtech.com RClamp0582B Low Capacitance TVS for ESD and Surge Protection PROTECTION PRODUCTS - RailClamp® ® ® ® ® Description Features Dimensions Schematic & PIN Configuration Revision 10/13/2010 RailClamp® TVS diodes are specifically designed to protect sensitive components which are connected to high-speed data and transmission lines from overvolt- age caused by ESD (electrostatic discharge), CDE (cable discharge events), and EFT (electrical fast transients). The RClamp®0582B features high peak pulse current capability (Ipp=15A, tp=8/20us) 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). This means it can be used on high-speed inter- faces such as USB 2.0 and LVDS data lines. 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 bidirec- tional 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 com- patible with both lead free and SnPb assembly tech- niques. 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 surge protection makes them a flexible solution for applications such as set top boxes, displays, and portable electronics.
