... Note the effect of property 2. This means you can’t go sticking a voltage across the base-emitter terminals, because an enormous current will flow if the base is more positive than the emitter by more than about 0.6 to 0.8 volt. This rule also implies that an operating transistor has Vb = ~ Ve + 0.6 ...
