Please log in for more thread options Hello Elk,
The Prefix in the symbol should be X, because it's a subcircuit model. SYMATTR Prefix MP -->
SYMATTR Prefix X
Normally you should set the X in the symbol editor of course. I have sent you an example with a specific symbol for the BUZ272. If your email-address doesn't work, please send me a valid email-address. Either keep the model file in the directory of the schematic or in the LTspice folder ...\Swcadiii\lib\sub\ You could also make a universal symbol for all subcircuit-Mosfets with the pin-order G, S, D. There is a large user group for LTspice. http://tech.groups.yahoo.com/group/LTspice/ Best regards, Helmut > Hello,
