Description

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.
