RClamp0502A RailClamp Low Capacitance TVS Array PROTECTION PRODUCTS - RailClamp Features Description Transient protection for high-speed data lines to The RailClamp series consists of ultra low capacitance TVS arrays designed to protect high speed data inter- IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) faces. This series has been specifically designed to IEC 61000-4-4 (EFT) 40A (5/50ns) protect sensitive components which are connected to Flow through design for ease of layout for high high-speed data and transmission lines from overvoltage speed data line application caused by ESD (electrostatic discharge), CDE (Cable Protects up to two I/O lines & power line Discharge Events), and EFT (electrical fast transients). Low capacitance (<0.9pF) for high-speed interfaces They are designed for use in applications where board 2 Ultra-small package requires less than 2.9mm of space is at a premium. Each device requires less than PCB area 2 2.9mm of PCB area and will protect two high speed Low leakage current and clamping voltage data lines. Low operating voltage: 5.0V The monolithic design incorporates surge rated, low Solid-state silicon-avalanche technology capacitance steering diodes and a TVS diode in a single Mechanical Characteristics package. Each line has a typical capacitance of 0.9pF to ground and 0.3pF between lines. The capacitance of SC-89 (SOT-666) package each line is well matched for consistant signal balance. RoHS/WEEE Compliant Signal integrity is further preserved with the flow through Lead Finish: matte tin design. A connection to the TVS is provided for protec- Molding compound flammability rating: UL 94V-0 tion of external voltage busses, such as those found in Marking: A USB applications. This device is optimized for ESD Packaging: Tape and Reel protection of portable electronics. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Applications Level 4 (15kV air, 8kV contact discharge). USB 2.0 High Speed The RClamp0502A is in a 6-pin, RoHS/WEEE compli- 10/100/1000 Ethernet Ports ant, SC-89 (SOT-666) package. It measures 1.6 x 1.6 High-Definition Multimedia Interface (HDMI) x 0.6mm. The leads are finished with lead-free matte Digital Visual Interface (DVI) tin. The small package makes it ideal for use in por- table electronics such as cell phones, laptops, and Monitors and Flat Panel Displays digital still cameras.
