LCDA12C-8 Datasheet | SEMTECH

Description The LCDAxx C-8 has been specifically designed to protect sensitive ponents which are connected to data and transmission lines from over voltages caused by ESD (electrostatic discharge), EFT (electrical fast transients), and lightning. The low capacitance array configuration of the LCDAxx C-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 LCDAxx C-8 suitable for telemunications systems operating in harsh transient environments. The low inductance construction minimizes voltage overshoot during high current surges. The features of the LCDAxx C-8 are ideal for protecting multi-protocol transceivers in WAN applications such as Frame Relay systems, routers, and switches.
