FEATURES AND BENEFITS
SO-8
Dedicated to the protection of sensitive telecom
equipment, the LCP3121 provides protection
which can be programmed by both voltage and
current.
The breakdown voltage can be easily programmed
by using an external zener diode.
The protection function programmed by the
current
is achieved with the use of a resistor
between the gate and the cathode. The value of
the resistor will determine the level of the desired
current before the triggering of the device.
A multiple protection mode is also performed when
using several diodes providing each line interface
with an optimized protection level.
If desired, a bidirectional protection function can
be achieved by the use of two LCP3121.
