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 RB
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. Fig.6 gives RB
characteristics.
