For a BJT Ic - VCE output characteristics:
The characteristic lines are parallels to the horizontal axis, because of the Early-effect.
In active mode of a BJT the CB layer is forwardly biased and its value is approx. +0.7V
The saturation voltage of a BJT is a residual voltage of the VBE voltage
The α (alfa) parameter of a BJT is the quotient of the emitter and base current.
The collector current of a BJT is a linear function of the VBE voltage.
The output signal of a BJT is the collector current.
The voltage potential at the collector of a BJT must be lower than the voltage potential at the base, in the saturated operational mode. (the reference is the emitter)
A BJT can only be used for signal amplification.
The β parameter of a small signal, discrete, real BJT highly temperature dependent and scatters highly from item to item.
To control the operation of a BJT can only be happen by opening/closing the forwardly biased Base-Emitter PN junction.
