Hi everyone...I am looking for the suitable values for Bf and Br
values and also Is (saturation current) and Ise (leakage saturation
current) in order to make The 2N2222 transistor more like a typical IC
BJT. I couldn't able to find anywhere. most places they onley have the
standared parameters that come with the transistor. I will very much
apreciate the help. Thank you,
Esayas.

Hi Esayas,

This is a Spice model I have.

..model Q2N2222 NPN(Is=14.34f Xti=3 Eg=1.11 Vaf=74.03 Bf=255.9 Ne=1.307
+ Ise=14.34f Ikf=.2847 Xtb=1.5 Br=6.092 Nc=2 Isc=0 Ikr=0 Rc=1
+ Cjc=7.306p Mjc=.3416 Vjc=.75 Fc=.5 Cje=22.01p Mje=.377 Vje=.75
+ Tr=46.91n Tf=411.1p Itf=.6 Vtf=1.7 Xtf=3 Rb=10)

According to this, Bf=255.9, Br=6.092 and Is=Ise=14.34fA (1fA = 10^(-15) A)

HTH,
