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.
