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 degra-

dation.

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 con-

struction minimizes voltage overshoot during high

current surges.

The LCDAxxC-1 may be used to protect ADSL inter-

faces, multi-protocol serial transceivers, portable

electronics, and wireless systems.
