UDT14A05L03

UDT14A05L03 Electrostatic Discharged Protection Devices (ESD) Data Sheet Description UDT14A05L03 is surge rated diode arrays designed to protect high speed data interfaces. It has been specifically designed to protect sensitive components which is connected to data and transmission lines from overvoltage caused by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. The unique design of the device incorporates one surge rated, and two data lines. Low capacitance steering diodes and a TVS diode in a single package. The low capacitance array configuration allows the user to protect two high speed data or transmission lines. The two inductance construction minimizes voltage overshoot during high current surges.
