returns to its initial state (region 4).

Furthermore, the CLP30-200B1 switches when an overvoltage, either positive or negative,

occurs either:

■

simultaneously on both TIP and RING lines versus GND

■

between TIP and RING

■

on TIP (or RING) versus GND

This current (typically above 150 mA) should not activate the protection device CLP30-

200B1.

Therefore the level of activation is to be chosen just below this limit (typically 200 mA). This

maximum.

In this case, the positive triggering will be 220 mA min and 320 mA max.

Thanks to the CLP30-200B1 topology, the surge current in the line is reduced after it.

the external voltage reference device may be kept low.

This results in a significant cost reduction for the whole system.
