LCDA12C-1 and LCDA15C-1
Low Capacitance TVS Diode Array
PROTECTION PRODUCTS
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 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.
