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 “4-point” configuration ensures a reliable protection, eliminating overvoltages introduced by the parasitic inductances of the wiring (Ldi/dt), especially for very fast transient overvoltages.

This is a GO-NOGO Test which allows to confirm the holding current (I test circuit.
TEST PROCEDURE :
1) Adjust the current level at the IHvalue by short circuiting the AK of the D.U.T.
2) Fire the D.U.T with a surge Current : Ipp = 10A , 10/1000 µs.
3) The D.U.T will come back off-state within 50 ms max.
