DUAL FORWARD-CONDUCTING P-GATE THYRISTORS
PROGRAMMABLE OVERVOLTAGE PROTECTORS
section 4.5.12 - first-level power fault testing
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
series resistor will result in table 4. I

column values of 2x0.45, 2x0.9, 2x1.4, 2x1.4, 2x0.4 and
2x0.23. The TISP61089S will survive these peak current values as they are lower than the TISP61089S
ratings.
section 4.5.13 - second-level power fault testing
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.
