The breakdown voltage is where the transistor will stop operating or be destroyed if it is given an input voltage of that amount. As discussed before, the voltage a circuit receives from a source depends on its input impedance as well as the internal impedance of the source, while the voltage it delivers depends on its output impedance as well as the load impedance. It is recommended that transistors not be allowed to operate near these values, lest their lifespan be shortened. Choosing transistor replacements electronics notes.
