Hello,for Bjt to be in working state. we need to V_B>V_E and V_C>V_B
How do i know the saturation current of 1.3A from mathematical point of view using the data sheet.
I know that the formula is as shown bellow.
the datasheet is as shown bellow:
\[\frac{A_{E}qD_{n}n_{i}^2}{N_{B}W_{B}}\] is called as \[ I_{s} \] (Saturation Current and you will never know this Manufacturer Parameters.That's why you should use given upper level circuit parameters
