I am trying to simulate LEDs in LTSpice and the PSpice model available looks like this:
.MODEL SPMWHT541ML5XAR0S0_AZ_Min D
+ IS=9.5E-26
+ N=1.83199622528087
+ RS=1.55320994268357
+ TRS1=-0.00109167328584789
+ TRS2=0
+ EG=2.1
+ XTI=27.4316298646001
*$
.MODEL SPMWHT541ML5XAR0S0_AZ_TYP D
+ IS=9.5E-26
+ N=1.88254340719771
+ RS=1.59634934164592
+ TRS1=-0.000948164679596289
+ TRS2=0
+ EG=2.1
+ XTI=30.8148132453387
*$
.MODEL SSPMWHT541ML5XAR0S0_AZ_MAX D
+ IS=9.5E-26
+ N=1.89968242930065
+ RS=1.61078235439033
+ TRS1=-0.00109389046815565
+ TRS2=0
+ EG=2.1
+ XTI=31.1809226106151
*$
In LTSpice I made 3 components based on the QTLP existing models as follows:
.model QTLP690C D(Is=1e-22 Rs=6 N=1.5 Cjo=50p Xti=100 Iave=160m Vpk=5 mfg=Fairchild type=LED)
.model LED_Min D(Is=9.5e-26 Rs=1.55320994268357 N=1.83199622528087 Cjo=50p Xti=27.4316298646001 Iave=200m Vpk=5 mfg=Samsung type=LED)
.model LED_TYP D(Is=9.5e-26 Rs=1.59634934164592 N=1.88254340719771 Cjo=50p Xti=30.8148132453387 Iave=200m Vpk=5 mfg=Samsung type=LED)
.model LED_MAX D(Is=9.5e-26 Rs=1.61078235439033 N=1.89968242930065 Cjo=50p Xti=31.1809226106151 Iave=200m Vpk=5 mfg=Samsung type=LED)
There are some parameters in the PSpice model that do not appear in the LTSpice ones. Any idea how importand those are(EG and TRS) and what is the effect?
