I am replacing an old TRIAC that is used for a solenoid driver driven by a photo-flash (I have dozens of these in my classic rifle gallery) and I can't find anything on line about this particular device.
I know it is 400V, 3A, and is in a TO-11 like metal can however what I can't find is the Gate current. This is a sensitive gate TRIAC and I suspect it is either a 3MA or a 10MA device, but would like a copy of the original TECCOR specs to be sure that the replacement I am using is close enough to the original for long term reliability. This is being controlled by a device called a Vactrol - VTL2C3, and I have several dozen of these controllers that eventually need upgrading.
So, if anyone has a TECCOR Electronics Inc. manual lying around from the early 70s and can scan me the page(s) on the Q4003M3 that would be great. I have found sheets online for other flavours of the Q4003 series, but just not the Mx version.
Thanks!
