SCR page
Turkey9, Sat Mar 27 2010, 11:56PMJust a little thing, but the section on the SCR page says that the main types are discrete and puck, were in my experience the stud type are some of the most used. It would be nice if it could be modified, as I don't have an account to do it myself.

If someone could take a picture of the different types it would be helpful too.

I dont know if these help, but they show some types of SCRs, the last picture came from a book that I have.

Has anyone tried to use a SCR as an amplifier? By considering the gate as the emitter and the cathode as the base and the anode as the collector we could call it a NPN transistor. By so biasing it this way we inhibit the binary action.
(ref sect 1-10 SCR Manual, 4th ed. 1967, General Electric)
Imagine marketing an amplifier using only SCR's.

radiotech, that picture came from the GE manual fifth edition, I dont know what year, but it is about the same.

I'll have to search to see if I have the 5th, I do remember that that topic seemed to disappear after the 4th. The circuit is AKA "remote based transistor"
Its old old stuff yet a Shur Shock fencer is in my shop that uses a programmable unijunction transistor from that era.

Keep in mind that we can't publish copyrighted material in the wiki. Pictures you take yourself are fine, but the picture from the book can't be used, unless someone is willing to use it as inspiration to create an original picture.

The 5th edition does have the section of remote bas transistors in Sect. 1.8. Same is the 4th.
Last night I located some SCR subassemblies and in them is a SCR the same as the picture. f take it apart, I'll photograph it and the driver board. It came from a first generation SCR drive.
