DESCRIPTION

Dedicated to the protection of sensitive telecom

equipment, the LCP3121 provides protection

which can be programmed by both voltage and

current.

PIN-OUT CONFIGURATION

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.

All cathod pins must be externally connected
