DESCRIPTION
Dedicated to telecommunication equipment
protection, these devices provide a triple
bidirectional protection function.
They ensure the same protection capability with
the same breakdown voltage both in longitudinal
mode and transversal mode.
A particular attention has been given to the internal
wire bonding. The 鈥?-point鈥?configuration ensures
a reliable protection, eliminating overvoltages
introduced by the parasitic inductances of the
wiring (Ldi/dt), especially for very fast transient
overvoltages.
Dynamic characteristics have been defined for
several types of surges, in order to meet the SLIC
maximum ratings.
