LCDA15C-6
LCDA15C-6 is Low Capacitance TVS Diode Array manufactured by SEMTECH.
Description
The LCDA15C-6 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 LCDA15C-6 allows the user to protect six 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 LCDA15C-6 suitable for telemunications systems operating in harsh transient environments. The low inductance construction minimizes voltage overshoot during high current surges. The features of the LCDA15C-6 are ideal for protecting multi-protocol transceivers in WAN applications such as Frame Relay systems, routers, and switches.
