> How does the negative temp coefficient help; stability for very high temps? You can put multiple switches in parallel, and have them self balance without resorting to active temperature compensation which is completely out of question for any consumer grade device. For power electronics, GaN is nowhere near as big of a bang as SiC, with its current handling being the primary showstopper. SiC can switch 100A loads at one kilovolt and above with ease, and at very high frequencies. There are simply no equivalent GaN part for this comparison. Second to that, GaN needs a tricky gate driver, and is normally an
n-channel depletion mode device. SiC can still be driven driverless at lo Second to that, SiC JFETs still have niche uses in audio amps exactly because of their "bad" shallow IV curve. |
