Semtech LCDA15C-8

Description

The LCDAxxC-8 has been specifically designed to protect sensitive components which are connected to data and transmission lines from over voltages caused by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. The low capacitance array configuration of the LCDAxxC-8 allows the user to protect eight high-speed data or I/O lines. They may be used on systems operating from 5 to 15 Volts. The high surge capability (500W, tp=8/20µs) makes the LCDAxxC-8 suitable for telecommunications systems operating in harsh transient environments. The low inductance construction minimizes voltage overshoot during high current surges.
