DESCRIPTION
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.
Witha stand-off voltage of 28Vand a very low ca­pacitance,thisdevice isable to protecthigh-speed interfacessuchas T1/E1interface.
