RCLAMP0504M.TBT

RailClamp0504M are surge rated diode arrays designed to protect high speed data interfaces. The RClamp series has been specifically designed to protect sensitive components which are connected to data and transmission lines from overvoltage caused by ESD (electrostatic discharge), EFT (electrical fast transients), and lightning.The unique design of the RClamp series devices incorporates four 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 RClamp0504M has a low typical capacitance of 3pF and operates with virtually no insertion loss to 1GHz. This makes the device ideal for protection of high speed data lines such as USB 2.0, Fire wire, and DVI interfaces.The RCIamp0504M is designed to have ease of layout by allowing the traces to run straight through the device. This ease of layout coupled with the low capacitance and clamping voltage of the RCIamp0504M makes it the superior choice for protecting four high speed lines.The low capacitance array configuration allows the user to protect four 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).
