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 I_{s} 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 (A_{E}), Electron Diffusivity (D_{n}), Thermal Equilibrium Value (n_{po}) 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.
