Bipolar Junction Transistor (BJT) Simulation

This simple simulation demonstrates the three states of a Bipolar Junction Transistor: off, active, and saturated. Use the and buttons to change the input voltage Vi. You may also enter in a voltage.

When doing this simulation, keep in mind the conditions for each state:
StateConditionsEffects
Off VBE < VBEon No current flow
Active VBE = VBEon
VCE >= VCEsat
iC / iB is constant, equal to Beta
Saturated VBE = VBEon
VCE = VCEsat
iC / iB is not constant, and less than Beta

Vi =
