Re: [TCML] Sidactors in a can of worms

Hi Finn,

Regarding the new sidacs in test: It sounds like, even though you went 
well above breakover, the Sidac simply performed a clamping (regulating 
voltage) action? Very odd, but might be neat for a hv regulating need. 
Actually, considering what the "designed for" application is, this is 
pretty cool and beats a switching topology, but of course we need the 
switching in our app.
