SRV05-4 RailClamp Low Capacitance TVS Diode Array PROTECTION PRODUCTS Features Description RailClamps are surge rated diode arrays designed to ESD protection for high-speed data lines to protect high speed data interfaces. The SR series has IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) been specifically designed to protect sensitive compo- IEC 61000-4-4 (EFT) 40A (5/50ns) nents which are connected to data and transmission IEC 61000-4-5 (Lightning) 12A (8/20s) lines from overvoltage caused by electrostatic dis- Array of surge rated diodes with internal TVS Diode charge (ESD), electrical fast transients (EFT), and Small package saves board space lightning. Protects four I/O lines The unique design of the SR series devices incorpo- Low capacitance: 3pF typical rates eight surge rated, low capacitance steering Low clamping voltage diodes and a TVS diode in a single package. During Low operating voltage: 5.0V transient conditions, the steering diodes direct the Solid-state silicon-avalanche technology transient to either the positive side of the power supply Mechanical Characteristics line or to ground. The internal TVS diode prevents over-voltage on the power line, protecting any down- JEDEC SOT-23 6L package stream components. Molding compound flammability rating: UL 94V-0 The SRV05-4 has a low typical capacitance of 3pF and Marking : V05 operates with virtually no insertion loss to 1GHz. This Packaging : Tape and Reel makes the device ideal for protection of high-speed data lines such as USB 2.0, Firewire, DVI, and gigabit Applications Ethernet interfaces. USB 2.0 Power and Data Line Protection The low capacitance array configuration allows the user Video Graphics Cards to protect four high-speed data or transmission lines. Monitors and Flat Panel Displays The low inductance construction minimizes voltage Digital Video Interface (DVI) overshoot during high current surges. They may be 10/100/1000 Ethernet used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (15kV air, 8kV contact dis- Notebook Computers charge).
