BJT In Reverse Avalanche Mode

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 sometimes referred to as negistors. Because the asymmetry and doping differences between the base-emitter and ...
