Transistor Switch Saturation Degree Calculator

Transistor into saturation, or the drive electronics switch.
Therefore, the calculation parameters is important.

Rc (the Collector resistor) collector resistance	(kΩ)
Positive voltage VP (Positive Voltage)	(V)
Beta _(min) (Current gain) amplification factor, the current gain
V _BE (Base to emitters drop) base - emitter voltage drop	(V)

Rb (the Base resistor) base resistance	(kΩ)

Saturated load current, the base current Ib = Ic / Beta. The transistor has a different gain, so we want to use the minimum value of beta, to ensure saturation.

Rb = (VP-V _BE ) / Ib = (VP-V _BE ) amplification factor / Ic = (VP-V _BE ) * zoom factor * Rc / VP
