RCLAMP0508M.TBT

RailClamp0508M are surge rated diode arrays designed to protect high speed data interfaces. The RCLAMP0508M series has been specifically designed to protect sensitive components which are connected to data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (cable discharge events), EFT (electrical fast transients), and lightning.The unique design of these devices incorporates surge rated, low capacitance steering diodes and a TVS diode in a single package. During transient conditions, the steering diodes direct the transient to either the positive side of the power supply line or to ground. The internal TVS diode prevents over-voltage on the power line, protecting any downstream components.The RCIamp0508M has a low typical capacitance of 3pF and may be used on lines operating up to 1GHz. This makes the device ideal for protection of high speed data lines such as USB 2.0, Fire wire, DVI, and gigabit Ethernet interfaces.The low capacitance array configuration allows the user to protect eight high-speed data or transmission lines. The low inductance construction minimizes voltage overshoot during high current surges. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (15kV air, 8kV contact discharge).
