Has anyone been having issues with SCR's (silicon controlled rectifiers)?
I've been trying a couple of different ones, and they just won't work for me!
I've viewed some schematics with SCR's in them, and it seems you can just connect them up like transistors... seems simple. A resistor connects to the gate of the SCR, and you connect a load (such as an LED). So why wouldn't they work? Is there a trick to it? I've tried connecting them both ways and still nothing.
I am using a 12V supply. I've tried various resistor values (for the gate) such as 10K, 2K and 1K. Attempting to trigger it fails.
I've tried a couple of SCR's from Jaycar Electronics, namely the C106B and C106Y. I can't even get an LED to light up!! Can anyone make a suggestion? It seems I am just wasting money on these dumb devices. Thanks. + | LED |  560R | Trigger (+) -----====------SCR Resistor | | -
