Hi there all,
I'm very new to Multisim :manindifferent: I'm using Multisim 11.0.
I have to following component used in a Power requlator circuit (2off):
http://uk.farnell.com/ixys-semiconductor/ixtn21n100/mosfet-n-sot-227b/dp/9359311
I have gone to the IXYS website and I've downloaded a P-Spice Model that I've attached:
http://www.ixyspower.com/PSpice_Model/MOSFET_TYPE/Standard_N-channel_Linear_Power_MOSFET.asp
Does this component model already exist within the Multisim component libary? If not how do I convert the attaced files to work with Multisim?
Thanks loads,

Great question! It doesn't look like that transistor is included natively, but it should be very fast to create. I highly recommend the video tutorial below as your first step - it explains how to create a component by using an existing component as a template. In your case - you would edit an existing NMOS and then simply replace the SPICE model to begin using it in your designs. Alternatively, you could use the component wizard (Creating a Custom Component in NI Multisim).
In terms of the attached file - Multisim support basic. DSN import (for more information, click here), so the library contents would need to be placed within a .DSN file if you wanted to import them like that.

Thanks for getting back to me Natasha,
The file I attached contains a .LIB and .OLB files... how do I get these to work?
Also... how do I go about getting the model data for this component as it doesn't seem to be on their site?
Many thanks,
Shay

The .LIB is the library file in which the SPICE model is stored. You can open it using Notepad or any other text editor. At that point you can copy and paste the model data. The .OLB are the symbol drawings - it wouldn't really be helpful in this case to copy this over since there are several NMOS in the database already which you can re-use, however, if you at some point really want to copy over the symbol drawing of some other component you could do this by placing it within an OrCAD schematic (.DSN) file, and then importing that into Multisim.
So all you really need is the model data (the .LIB), which you included as a link in your last post. Let me know if you have any trouble with this at all.
