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. ...
