Anyone tried using some of the new SiC Mosfets in any of Nelson's high current class audio designs, eg Zen variations?
For example the maximum ratings of the Cree C2M0280120D or Rohm SCTMU001F look comparable with the IRF044n, the threshold voltages are a little lower at around ~2.5V and the transconductances are lower at ~ 3S.
The transfer characteristics look more triode like and the parasitic capacitances look much better, eg Cis = 259pf for the Cree C2M0280120D vs 1500pf for the IRF044n.
