TSIxxB1
TEST # 1
LIGHTNING SIMULATION
This test concerns the 10/700 µs waveform surge,
± 1.5 kV.

The surge generator used for the test has the
following circuitry (fig.2).

The 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
for a 1.5 kV positive surge (fig.3a) and negative surge (fig. 3b)
These curves show the peak voltage the surge
generates across the TSI200B1 + and -
terminations. This lasts a short time (≈ 2 µs) and
after, as the internal protection gehaves like a short
circuit. The voltage drop across the TSIxxB1
becomes a few volts. In the meanwhile all the
surge current flows in the protection.
As far as the 10/700 µs waveform surge test is
concerned,the TSIxxB1 withstand the ± 1.5 kV
test.
