Hello guys ..I have a challenge. I used 1N4002 diode model in my Ltspice circuit design but then the LTSPICE can't find the model so i m having challenges at simulation. Can anyone help me with model information for 1N4002 diode ? Thanks

Just to be clear:
  1. Did you have the simulation running and suddenly it stopped running, OR
  2. Has the simulation never run correctly.

If you don't have the 1N4002 model in your LTspice library, it is available to add to it.
I can post the file if you need it.

If you definitely have the model, then the model file is not in the correct folder for LTS to find it, or else you do not have an include directive in your schematic.
If you are running LTS under Win10, third party model files would normally go in the same folder as your asc file, or else in the default User/Documents/LTS/lib/sub folder.

Yes I would be grateful ...I need it
Here is the 1N400x model info I use:

.MODEL 1N4001 D(IS=2.55E-9 RS=0.042 N=1.75 TT=5.76E-6 CJO=1.85E-11 VJ=0.75 M=0.333 BV=50 IBV=1E-5 Iave=1A Vpk=50 type=silicon)
.MODEL 1N4002 D(IS=2.55E-9 RS=0.042 N=1.75 TT=5.76E-6 CJO=1.85E-11 VJ=0.75 M=0.333 BV=100 IBV=1E-5 Iave=1A Vpk=100 type=silicon)
.MODEL 1N4003 D(IS=2.55E-9 RS=0.042 N=1.75 TT=5.76E-6 CJO=1.85E-11 VJ=0.75 M=0.333 BV=200 IBV=1.98E-5 Iave=1A Vpk=200 type=silicon)
.MODEL 1N4004 D(IS=2.55E-9 RS=0.042 N=1.75 TT=5.76E-6 CJO=1.85E-11 VJ=0.75 M=0.333 BV=400 IBV=3.95E-5 Iave=1A Vpk=400 type=silicon)
.MODEL 1N4005 D(IS=2.55E-9 RS=0.042 N=1.75 TT=5.76E-6 CJO=1.85E-11 VJ=0.75 M=0.333 BV=600 IBV=5.92E-5 Iave=1A Vpk=600 type=silicon)
.MODEL 1N4006 D(IS=2.55E-9 RS=0.042 N=1.75 TT=5.76E-6 CJO=1.85E-11 VJ=0.75 M=0.333 BV=800 IBV=7.89E-5 Iave=1000m Vpk=800 mfg=GP1000V1A type=silicon Iave=1A Vpk=800 type=silicon)
.MODEL 1N4007 D(IS=2.55E-9 RS=0.042 N=1.75 TT=5.76E-6 CJO=1.85E-11 VJ=0.75 M=0.333 BV=1000 IBV=9.86E-5 Iave=1000m Vpk=1000 mfg=GP1000V1A type=silicon )


Copy this and add into your standard.dio file in the CMP directory in your LTC folder.

Edit: Then if you right click on the diode symbol and select "Pick New Diode", the listing for those will show.
