SiC gives us some hope for decent devices (also) for audio.

Probably, maybe trying to counter all the fakes on the market, the Cob figures are better though so maybe some small improvements made and seems these are rohs compliant.

English datasheets are available from toshiba website.

After months of waiting for an order, Ive finally received Sankens latest range 2 weeks ago, these are marketed by allegro, after some tests and these are my new favourites.

The slightly better sepcs of TT1943/5200 is no more
than selection at the factory output chain of the better
devices, exactly the same way that processors of different
frequency are binned...
