FEATURES
Dedicated to dataline protection , this device
provides a triple protection function. It ensures
the same protection capab ility with the same
breakdown voltage both in common mode and
in diffe rential mod e.
With a stand-off voltage of 28V and a very low ca-
pacitance, this device is able to protect high-speed
interfaces such as T1/E1 interface.

D.U.T
This is a GO-NO GO test which allows to confirm the holding current (I
H
) level in a functional test circuit.
TEST PROCEDURE :
- Adjust the current level at the I
H
value by short circuiting the D.U.T.
- Fire the D.U.T. with a surge current : I
pp
= 10A, 10/1000
s.
- The D.U.T. will come back to the off-state within a duration of 50 ms max.
