How to Calculate Saturation current?
Saturation current calculator uses Saturation current=Cross-section area of base-emitter junction*[Charge-e]*Electron Diffusivity*Thermal Equilibrium Value/Width of base to calculate the Saturation current, The Saturation current for a BJT is the point where a further increase in base current will not result in a corresponding increase in collector current. Saturation current and is denoted by Is symbol.
How to calculate Saturation current using this online calculator? To use this online calculator for Saturation current, enter Cross-section area of base-emitter junction (AE), Electron Diffusivity (Dn), Thermal Equilibrium Value (npo) and Width of base (L) and hit the calculate button. Here is how the Saturation current calculation can be explained with given input values -> 1.025E-26 = 0.08*[Charge-e]*8E-05*0.04/4.
