(10 sec duration) Thermal Resistance Junction-to-ambient Junction and Storage Temperature Range Value 15 8 385 260 325 -55 ~ +150 Units KV mW °C °C / W °C Stresses exceeding "Maximum Ratings" may damage the device. "Maximum Ratings" are stress ratings only; functional operation above the recommended. Operating conditions is not implied. Extended exposure to stresses above the recommended operating conditions may affect device reliability. 1. FR-5 = 1.0 x 0.75 x 0.62 in. 2. Only 1 diode under power. For all 4 diodes under power, PD will be 25%, mounted on FR-4 board with min pad.

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/ Any changes of specification will not be informed individually. 24-Aug-2008 Rev.
