What is saturation current in transistor?

the transistor will be biased so that the maximum amount of base current is applied, resulting in maximum collector current resulting in the minimum collector-emitter voltage drop which results in the depletion layer being as small as possible and maximum current flowing through the transistor. Therefore the transistor is switched “Fully-ON”.Then we can define the “saturation region” or “ON mode” when using a bipolar transistor as a switch as being, both junctions forward biased, VB > 0.7v and IC = Maximum. For a PNP transistor, the Emitter potential must be positive with respect to the Base.

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.

FAQ

What is 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 and is represented as I_s=A_E*[Charge-e]*D_n*n_po/L or Saturation current=Cross-section area of base-emitter junction*[Charge-e]*Electron Diffusivity*Thermal Equilibrium Value/Width of base. The Cross-section area of base-emitter junction is the width in the direction perpendicular to the page, Electron Diffusivity is the diffusion current is a current in a semiconductor caused by the diffusion of charge carriers (holes and/or electrons), Thermal Equilibrium Value is the value of the thermal equilibrium of the minority-carrier (electron) concentration in the base region and Width of base of the footing of the wall.

How to calculate Saturation current?
