I found that the BD140 having problem,

.MODEL BD140 PNP (IS=1e-09 BF=650.842 NF=0.85 VAF=10 IKF=0.0950125 ISE=1e-08 NE=1.54571 BR=56.177 NR=1.5 VAR=2.11267 IKR=0.950125 ISC=1e-08 NC=3.58527 RB=41.7566 IRB=0.1 RBM=0.108893 RE=0.000347052 RC=1.32566 XTB=19.5239 XTI=1 EG=1.05 CJE=1e-11 VJE=0.75 MJE=0.33 TF=1e-09 XTF=1 VTF=10 ITF=0.01 CJC=1e-11 VJC=0.75 MJC=0.33 XCJC=0.9 FC=0.5 CJS=0 VJS=0.75 MJS=0.5 TR=1e-07 PTF=0 KF=0 AF=1 Vceo=80 Icrating=1.5)

The IS isn't that big, can any one give me an accurate model ?

If that's from OnSemi, it's garbage. Get the one from Fairchild.

hey .. thanks alot .. but another help .. I dunno the J511 diode model and also the BAT85 diode model and BZX79C12V diode, these three models of diodes. I found their datasheet but i dunno is it correct to put inside the LTspice . Can anyone help me give me advise on it model of LTSpice?
