Transistors operating in their avalanche regions are often used to generate fast rise pulses (seeavalanche pulse generator using 2N3904). Many transistors can also avalanche when the connections to collector and emitter are reversed. When operating in reverse avalanche region, these transistors are somet...

at first, theactive region, here the BJT will be operating normally and the emitter junction is reverse biased. Next comes thesaturation regionwhere both the emitter and collector junctions are forward biased. Finally, thecutoff regionwhere both emitter and the collector junctions are reverse biased...
When the reverse recovery time period is known, an error in the peak current obtained due to the reverse recovery time period may be calculated. The calculated error may be used to offset the target peak current for controlling the switching of the BJT to begin a turn-off transition of the...

After reading this thread I would say Q23 will be in reverse active mode of operation operating with lower β and therefore it does affect the operation of the circuit on the left. My questions are: 1) What is it that actually happens by placing Q23 on the...
