FEATURES

Dedicated to dataline protection, this device provides a triple protection function. It ensures the same protection capability with the same breakdown voltage both in common mode and in differential mode. With a stand-off voltage of 28V and a very low ca- pacitance, this device is able to protecthigh-speed interfacessuch as T1/E1 interface.

TEST PROCEDURE : - Adjust the current level at the IH value by short circuiting the D.U.T. - Fire the D.U.T. with a surge current : Ipp = 10A, 10/1000µs. - The D.U.T. will come back to the off-state within a durationof 50 ms max.
