Wiki describes the highest rated silicon switching Transistor @ 1Kv ( I don't know what they meant as per "rating" but if you look at the "disadvantages" of silicon-based transistors they claim 1Kv as a limitation....?) ... I was wondering what are some of the highest HV parts currently available? Has any investigated the "Guinness Book of World's Records" rating of (single unit) Transistors, Capacitors & other passive components? With passive discrete parts that would raise some problems with resistors, I suppose Is there currently a standing strength/size recorded for a single CPU (not multiple core)? What are some of the highest rated parts available?

I have seen datasheets for 6.5kV (IIRC) IGBTs for use in trains, but I don't know if they are multiple units in series internally, but I think they aren't.
When it comes to capacitors, I don' know of anyone making higher voltage caps than General Atomics, they have some caps rated for higher than 2MV here:

I think the most powerfull switching devices (IGBT and thyristors) are used in HVDC power line systems. Something like this nice piece of silicon here...

Almost all high voltage switching devices are comprised of many "smaller, lower voltage" junctions in series. its just a matter of packaging the dies properly.

would it be posible to make transisters in series by connecting the emitter to colecter and bases in parralel, if it could what would the o0ther effcts be

Well you can hook two transistors together in a darlington arrangement. About half way down it explains the darlington transistor and has a circuit diagram. Basically it will just increase the gain by hfe1xhfe2, So it will require a very small signal for it to turn on.
