In motor control applications, the ability to turn off safely due to a load or equipment short-

circuit is a very important requirement on the power switching device.

When a current overload occurs, collector current rises rapidly so the power device limits

the current amplitude to a safe level for a period of time that allows the control circuit to

detect the fault and turn the device off.

Specific IGBT technology and series are produced to show such features.
