[TCML] SCR tesla coil



Dear List
I understand the rate of change in current with time (dI/dt) in the switching device in a TC is considerable. Is it still the case that only The SCRs capable of handling such severe duty are those with "interdigitated" gate construction e.g GTOs or has modern SCR technology changed this. Would a modern modern hockey-puck SCR such as the one described  here http://www.ebay.co.uk/itm/Capsule-thyristor-N195CH12-390A-ITav-/320794404043?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item4ab0d624cbwith ratings of 1200V and 390A be of running at least a small TC would the turn-on still be too slow?
