I'm looking at the IRFP4110PbF datasheet and trying to figure out what my Rds(on) will be @ a junction temp of 120C. The "rated" typical value is 3.7mΩ and the "max" is 4.5mΩ, but when I look at the graph, 120C corresponds to about 1.75. That makes me think it is a multiplier, but if I multiply 3.7 * 1.75 I get 6.5mΩ. so what gives?
