Spice model for CREE LED into Multisim

[mackenzista]

Hello,

I have followed the steps for Multisim component creation but I had no success.

The model I have is this:

*Cree XT-E HVW LED
*Model valid for 10mA to 60mA & Tj=85C
.MODEL XT-E HVW D
+ IS=5.39813E-12
+ N=82.08123424
+ RS=72.50212792
+ XTI=1960.735416
+ EG=2.5000

How can I add as a new LED for circuit simulation?

The same applies to the component NSIC2020BT3G from ONSEMI, which is PSPICE model .lib, when I open into text edit, it says

**$ENCRYPTED_LIB
**$INTERFACE
* PSpice Model Editor - Version 16.5.0

Hello,

What's your Multisim version? One thing I noticed is that this model has an error in the third line:

.MODEL XT-E HVW D  

The correct syntax is: .MODEL XT-E_HVW D

Therefore we have:

*Cree XT-E HVW LED
*Model valid for 10mA to 60mA & Tj=85C
.MODEL XT-E_HVW D
+ IS=5.39813E-12
+ N=82.08123424
+ RS=72.50212792
+ XTI=1960.735416
+ EG=2.5000

When creating the component, select the LED (or Diode) symbol from the Master Database. This will make things easier. One thing to note is that this LED will not blink since this model is basically modeling a diode.

The model for the NSIC2020BT3G is encrypted, there is no way to use this model in Multisim.

Hello ,

I'm using Multisim 12.

I have downloaded that model from Cree website...

I'll try the modifications you suggested , thank you.

About the encrypted model, I'll ask  Texas about a regular file.

Best Regards
