The KS33J4 may be used on line where the signal polarities are above or below ground.KS33J4 can with stand and provides protection from a surge of 40 watts peak pulse power per line for a 8/20 μs waveform. High speed data line Typical application for uni-directional protection of four lines. http://www.SeCoSGmbH.com/ 24-Aug-2008 Rev. B Any changes of specification will not be informed individually.
