Well, a few days ago I picked up this $5 SCR from a store in Toronto, however I can't seem to find any datasheet or information on it whatsoever.

Markings on the SCR are:
PRX 8493622 with a faded (what appears to be) C904 next to it. If anyone knows what this is, or what voltage/current it can handle speak up since I can get several more, I could build up my SCR stock for a few accidents. Pictures follow:

judging from the size, im saying atleast 600v, and 100A, probably 3KA surge.

There seems to be some markings on the bolt, can you read those and tell us what they are as well. From a quick google search, PRX seems to be the manufacturer, here is a link to their site.

I just realized that under 'authorized sales distributors' on PWRX's site, Canada is listed as a American state. I didn't get the memo that Bush secretly finalized the NAU. I couldn't find anything but judging by the various SCR's, I could always build a small-ish cap bank and see what happens for a 5 buck part.
