DESCRIPTION
Dedicated devices for ISDN interface and high
speed data telecom line protection. Equivalent to
a triple TRISIL with low capacitance.
These devices provide :
-
low capacitance from lines to ground, allowing
high speed transmission without signal
attenuation.
-
good capacitance balance between lines in
order to ensure longitudinal balance.
-
fixed breakdown voltage in both common and
differential modes.
-
the same surge current capability in both
common and differential modes.
-
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.
