What are you making that uses an SCR? Something high(ish) voltage?

Think of an SCR as a transistor that feeds itself. This allows a tiny control signal to activate it, but it means that you can't turn it off at the gate - something else needs to cut the current off.

This means that it has a lot of transistor like properties. Most importantly, its dissipation mode is a voltage drop - this makes it good for high voltage applications.

Please let us know what you are up to, it sounds interesting.
