Overview
The SRV05-4.TCT is a surge-rated transient voltage suppressor (TVS) diode array manufactured by Semtech Corporation. This component is designed to protect high-speed data interfaces from overvoltage caused by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. The SRV05-4.TCT features a unique design that incorporates eight surge-rated, low capacitance steering diodes and a TVS diode in a single package, directing transients to either the positive side of the power supply line or to ground, thereby protecting downstream components.
