Mosfet vth temperature coefficient

WebAug 15, 2024 · The MOSFET dissipation is 2.5mW (10V x 250uA), so not too much in the way of self heating. That gave a change of 6mV before it settles. Something worried me about that curve. It seemed to go in the wrong direction - the curves in the datasheet imply that the Vgs(th) temperature coefficient is negative - so what was I looking at? WebMOSFET datasheet, two additional figures are introduced as well. One is R DS(on) vs V GS graph since R DS(on) varies by different amplitude of V GS. The other one is R DS(on) …
