The most significant tests are a long duration (900 s) medium current test and a higher current tests of 60 one
second power applications. As shown in table 4, the peak currents for these tests are 2x0.37 A and 2x1.3 A
respectively. The TISP61089S will survive both these conditions as its ratings are 2x0.93 A and 2x4.5 A for
these time periods

Using a 25
2x0.23. The TISP61089S will survive these peak current values as they are lower than the TISP61089S
ratings.
The two most significant tests are a long duration (900 s) medium current test and a higher current 5 s test.
As shown in table 5, the peak currents for these tests are 2x17 A and 2x7.7 A respectively. For the
TISP61089S to survive this test, the series current limiting element must operate within 0.1 s and 0.5 s
respectively.
