3.1.9 SCSOA
Fig.3-1-14~19 show the typical SCSOA performance curves of each products.
The measurement condition is described as follows;
(1) for 1200V series, V
CC
=800V, Tj=125°C at initial state, V
CC(surge)
≤1000V(surge included), non-repetitive,2m load.
(2) for 600V series, V
CC
=400V, Tj=125°C at initial state, V
CC(surge)
≤500V(surge included), non-repetitive,2m load.
Please refer Fig.3-1-17 for PSS25MC1FT(25A/1200V CIB type), for instance. It shows can safely shut
down an SC current which is about 10 times of its current rating under above conditions, when the IGBT shuts off
by 4.6
μs at V
D
=16.5V. Since the SCSOA (Short Circuit Safety Operating Area) will vary with the control supply
voltage, DC-link voltage, and so on, it is necessary to set time constant of RC filter with a margin.
