RClamp0504M RailClamp Low Capacitance TVS Diode Array PROTECTION PRODUCTSPROTECTION PRODUCTS PRELIMINARY Features Description RailClamps are surge rated diode arrays designed to ESD protection for high-speed data lines to protect high speed data interfaces. The RClamp series IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) has been specifically designed to protect sensitive IEC 61000-4-5 (Lightning) 12A (8/20s) components which are connected to data and transmis- IEC 61000-4-4 (EFT) 40A (5/50ns) sion lines from overvoltage caused by ESD (electrostatic Array of surge rated diodes with internal TVS Diode discharge), EFT (electrical fast transients), and lightning. Small package saves board space The unique design of the RClamp series devices incorpo- Protects four I/O lines and one Vcc line rates four surge rated, low capacitance steering diodes Low capacitance: 3pF typical and a TVS diode in a single package. During transient Low clamping voltage conditions, the steering diodes direct the transient to Low operating voltage: 5.0V either the positive side of the power supply line or to Solid-state silicon-avalanche technology ground. The internal TVS diode prevents over-voltage on the power line, protecting any downstream components. Mechanical Characteristics TM The RClamp 0504M has a low typical capacitance of JEDEC MSOP 10L package 3pF and operates with virtually no insertion loss to Molding compound flammability rating: UL 94V-0 1GHz. This makes the device ideal for protection of high- Marking : Marking code and date code speed data lines such as USB 2.0, Firewire, and DVI Packaging : Tape and Reel per EIA 481 interfaces. Lead Finish: Matte Tin The RClamp0504M is designed to have ease of layout by allowing the traces to run straight through the device. Applications This ease of layout coupled with the low capacitance and Digital Video Interface (DVI) clamping voltage of the RClamp0504M makes it the 10/100/1000 Ethernet superior choice for protecting four high speed lines. Monitors and Flat Panel Displays The low capacitance array configuration allows the user Notebook Computers to protect four high-speed data or transmission lines. High Definition Multi-Media Interface (HDMI) The low inductance construction minimizes voltage USB 2.0 Power & Data Line Protection overshoot during high current surges. They may be used to meet the ESD immunity requirements of IEC 61000-4- IEEE 1394 Firewire Ports 2, Level 4 (15kV air, 8kV contact discharge).
