From: Hammy on 13 Jan 2010 21:12 Anybody hear of a mosfet that only has a 7.5% increase in RDSON between 25C and 100C. Because according to ST the STD15NF10 is just such a mosfet. I'm guessing this is a typo. Data sheet pg7 figure 11. http://www.st.com/stonline/products/literature/ds/7080.pdf

Oh well better then Vishay's IRL120 Data sheet which has no labeling for the X or Y axis. http://www.vishay.com/docs/91324/91324.pdf I know its usually 1.5 to 2 times higher at 100C but still....:)
