For inductive loads, high voltage and high current must be sustained simultaneously during turn-off, in most cases, with the base to emitter

junction reverse biased.

Under these conditions the collector voltage must be held to a safe level at or below a specific value of collector current.

This can be accomplished by several means such as active clamping, RC snubbing, load line shaping, etc.

The safe level for these devices is specified as Reverse Bias Safe Operating Area and represents the voltage-current conditions during reverse

biased turn-off.

This rating is verified under clamped conditions so that the device is never subjected to an avalanche mode.

Figure 11 gives the complete RBSOA characteristics.
