Ive got some basic questions about how to interpret data from a transistor data sheet basically when there is no graph to look at to get data from only a select list of x and y data points in a list.
Take for example a 2n2222 npn transistor it says in the data sheet
vbe(sat) at Ic = 150ma,IB = 15ma vce(sat) = 0.4v
vbe(sat) at Ic = 500ma,IB = 50ma vce(sat) = 1.6v
How would u get an idea of the expected vce(sat) if the Ic was 70ma and Ib was 10ma, also for any other values that lye between these points ?
In the datasheet under dc gain(hFe) it says this
IC = 0.1 mA; VCE = 10 V 35 hFe
IC = 1 mA; VCE = 10 V 50 hFE
IC = 10 mA; VCE = 10 V 75 hFe
IC = 150 mA; VCE = 1 V; 50 hFe
IC = 150 mA; VCE = 10 V;100hFe
So how would you get an idea of the dc gain(hFe) if Ic is 50ma and vce is 5v,
also for any other values that lye between these points ?
