Description

The LCDAxxC-1 is a low capacitance transient voltage suppressor TVS diode array. It is designed to protect sensitive CMOS ICs from the damaging effects of ESD and lightning. Each device will protect one line in common line-to-ground mode or one line pair in metallic Line-to-line mode. They are low capacitance < 15pF making them suitable for use on high-speed telecom and datacom interfaces without signal degradation.

The configuration of the LCDAxxC-1 has been optimized for easy layout on high density boards. The small SOT-143 package minimizes required board space. These devices will handle up to 20 Amps for an 8/20µs lightning impulse. The low inductance construction minimizes voltage overshoot during high current surges.
