The LCDA24C-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 LCDA24C-1 has been opti-

mized for easy layout on high density boards. The

small SOT-143 package minimizes required board

space. These devices will handle up to 10 Amps for an

8/20µs lightning impulse. The low inductance con-

struction minimizes voltage overshoot during high

current surges.

The LCDA24C-1 may be used to protect ADSL inter-

faces, multi-protocol serial transceivers, portable

electronics, and wireless systems.

... Secondary IC side protection is achieved with low voltage TVS devices. The LCDA24C-1 is connected between to transmit line pairs. Since the LCDA24C-1 has a working voltage of 24 volts, it may be used on pairs with signal swings as high as +/-12 volts. The SD05C is used to protect the receive pairs. ...
