3.1.11 SCSOA
Fig.3-1-16~17 show the typical SCSOA performance curves of each products.
(Conditions: Vcc=800V, Tj=125°C at initial state, Vcc(surge) ≤ 1000V(surge included), non-repetitive,2m load.)
In the case of PSS05S72FT, it can shutdown safely an SC current that is about 20 times of its current rating under
the conditions if the IGBT conducting period is less than about 4.5 μ s. Since the SCSOA operation area will vary
with the control supply voltage, DC-link voltage, and etc, it is necessary to set time constant of RC filter with a
margin.
