Onsemi EliteSiC MOSFET.

Richard Andrews Всі повідомлення цього користувача #154684 Happy Sunday, Anybody got a spice model of Onsemi's EliteSiC MOSFET. Maybe a NTHL015N065SC1.

I did that now, and I see they have one. Actually more than one. Download it. Chances are good that the PSpice model is generic SPICE. Chances are very good that their LTspice model works in LTspice.

Andy I Всі повідомлення цього користувача #154687 Well, all the models on that page are encrypted, including the LTspice model and the PSpice model. That means you can use only the LTspice model in LTspice. The PSpice encrypted model can only be used in PSpice, so in that sense it is not quite generic. Andy
Andy I Всі повідомлення цього користувача #154689 Richard, just in case you are not familiar with onsemi's product webpages: Start at the product webpage. For the NTHL015N065SC1, that would be here. Then click "Technical Documentation" which is one of the tabs on the large black band, part way down the page. This reveals much information. Scroll down until you see something that looks like "SPICE" or "Simulation" or "Model". (But not the "CAD Model", which is the physical package model.) Beneath it, it shows all the SPICE or SPICE-like models for the part which can be downloaded directly without any sweat - no need to request it, no need to sign away your rights to a fulfilling life or anything like that. Also they list Application Notes and White Papers which might be handy, but don't waste too much time on those if all you need is the SPICE model. I can't promise that all onsemi product webpages work this way, but most of the ones I have visited lately are like this. Andy
Richard Andrews Всі повідомлення цього користувача #154692 Yah, I checked to find a spice model and concluded that I'd have email tech support, but didn't want to go that route until I got to my desktop, and thought to asks around, because it's my Mom's Birthday, and I was away from my desktop.

I need to redo the screen captures because our web site has been upgraded since last AN revision. To understand how our models are build, read AN [4] or IEEE papers. Our models contains all our technology information, that is the reason why they are encrypted. If someone can read the model, he can copy our technology. But it is real SiC equations inside the SiC models and not curve fitting Silicon equations used for SiC. They are longer to simulate but much more accurate. AN above 7 in the list are examples. I hope it will help you to use onsemi SiC LTSpice models, Best regards, Didier.
