these two mosfets almost have the same specification http://pdf.datasheetcatalog.com/datasheet/fairchild/IRFP250.pdf
and
http://www.futurlec.com/Datasheet/Transistor/IRF250.pdf however IRfp250 for vishay is not mentioned that it has linear charcteristics , are they one product ?
http://www.vishay.com/docs/91212/91212.pdf isn't it supposed to be the same product for all companies , how will i determine which one of them is for fairchild and the other for vishay ?
