short-circuit safe operating area (SCSOA)

All combinations of collector current and collector-emitter voltage that are permitted to occur during nonrepetitive turn-off of short-circuit current in the transistor without endangering its survival.

NOTE 1 This information is normally presented graphically.

NOTE 2 The SCSOA is defined for nonrepetitive operation. This means that it applies for a limited number of occurrences in the life of a device and that all equilibrium conditions must be reestablished before a second occurrence.
