...?Fig. 2 : 10/700 μs waveform surge generator circuitThe behaviour of the TSI200B1 to this lightning surge is given below (fig. 3).Fig. 3 : Voltage across the TSI200B1 at the + and - terminations and current throught it ... ...These curves show the peak voltage the surgegenerates across the TSI200B1 + and -terminations. This lasts a short time (≈ 2 μs) andafter, as the internal protection gehaves like a short... ...and the current through it.The figure 6 shows that after 250ms there is nocurrent anymore flowing through the TSI200B1device. This is due to the action of the serial PTC...
