Hello mr. TK,

Personally i use the model for the 10M90 without problems (knock on wood). Contrary to you, i assumed they were the same except for the voltage rating. But then, this habit of assuming things has gotten me problems in the past :-)

I could not use the standard n-type mosfet symbol because the pinout is not the same. I modded the stock mosfet symbol and changed the pin assignment. However that is not the problem with the previous poster's model - its pinout fits standard nmos symbol.

I can make it to work this way:
Use the nmos symbol, go to advanced setting, set the "prefix" parameter to "X" and the "spicemodel" parameter to "10M45S" (without quotes). Of course the model goes into and .inc directive or in a included file.

In any case, here is a link to my symbol file that works with the 10M90 model. Save as into the Program Files/LTC/LTspiceIV/lib/sym directory or in your project's directory and it can be selected in the symbols menu.

Hope that helps.
Joris
