I have located a model for this. I will create a component for you, test it and post it tomorrow on a schematic so you can just download it to your database hopefully.
The easiest way to create components is to find a pre-made modes for them and do it that way instead of trying to do it from the datasheet. Doing it from the datasheet is possible, but is really an overly complex undertaking because like you said some of the information is hard to translate into what Multisim is looking for. And on top of that there are some parameters in Multisim that I have not found in the datasheet. This may just be me, but I think a more direct correlation between the datasheet info and Multisim parameters is needed or explained better in the documentation.
Creating components using pre-made models is not the majic pill in all circumstances. Sometimes models do not exist or are not compatible with Multisim. But when you can find them and they work it is much less of a headache creating a part.
Be back tomorrow with your part.
Thanks for the feedback. I am glad it worked and that you did good on your lab work. I will be uploading this to the files area at the site in my signature
You might want to examine this site as it contains a few components and other things concerning Multisim that may be of interest. It is free for everyone. You do have to register, but that is mainly for member tracking purposes only (so we know how many members we have, basically.). It is run independently from NI by members of this forum (including myself) so we can provide a stop gap measure for some missing components and what not.
Thanks a lot for the great component. It worked well for me. I'm actually also actively searching for 2n5457. It would be great if anyone can help me out.
