Now we get VAF = 139.172:
set the value found and continue with the next graph datasheet: hfe versus current collector:
Let’s add couples of data taken from this chart, and after data extraction we obtain the following curve:
From this curve we can extract: BF=212.95, IKF= 208.44 mA, ISE = 65.20fA, NE = 1.37, NK = 0.839:
