RClamp0502BA Low Capacitance RailClamp ESD & CDE Protection PROTECTION PRODUCTS Description Features Transient protection for high-speed data lines to RailClamp TVS diodes are specifically designed to IEC 61000-4-2 (ESD) 18kV (air), 12kV (contact) protect sensitive components which are connected to IEC 61000-4-4 (EFT) 40A (5/50ns) high-speed data and transmission lines from overvoltage IEC 61000-4-5 (Surge) 5A (8/20s) caused by ESD (electrostatic discharge), CDE (cable Protects up to two I/O lines discharge events), and EFT (electrical fast transients). Low capacitance (<1pF) No insetion loss to > 3.0 GHz Low profile (<1mm) The RClamp0502BA has a typical capacitance of only Low leakage current and clamping voltage 0.50pF (pin1 to 2). This means it can be used on circuits Low operating voltage: 5.0V operating in excess of 3GHz with minimal signal Solid-state silicon-avalanche technology attenuation. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (18kV Mechanical Characteristics air, 12kV contact discharge). Each device can be configured to protect 1 bidirectional line or two SC-75 (SOT-523) package unidirectional lines. Lead Finish: Matte Tin Pb-Free, Halogen Free, RoHS/WEEE Compliant Molding compound flammability rating: UL 94V-0 These devices are in a small SC-75 (SOT-523) package Packaging: Tape and Reel and feature a lead-free, matte tin finish. They are compatible with both lead free and SnPb assembly Applications techniques. They are designed for use in applications where board space is at a premium. The combination Mobile Display Digital Interface (MDDI) of small size, low capacitance, and high level of USB 2.0/USB 3.0 ESD protection makes them a flexible solution for GaAs Photodetector Protection applications such as HDMI, MDDI, antenna circuits, HBT Power Amp Protection Infiniband Transceiver Protection Automatic Test Equipment, USB 2.0/3.0, and Infiniband circuits.
