    I am looking for a source to buy silicon controlled rectifiers or switches.
    I have googled and found lots of explanations of how they work, but no part
    numbers or sources. Mouser does not seem to carry them.

    Mouser has the ST and Teccor parts.

    Hi, Joe. Like most of the catalog distributors, the "hard copy" catalog is a
    helpful addition to the web site.

    Mouse reps Teccor, a manufacturer of SCRs, triacs, and other thyristors. Look
    under Manufacturers -> Teccor to see their product selection.

    Try getting a catalog from the website. I find it helps a lot.

    Thank you gents, I do have a mouser catalog around here somewhere. I am
    remodeling a couple of rooms so I have no idea where it is right now, tho.
    I will go to the website and look up teccor.

    Of course, this leads me to another question. I was reading some of the
    information about how the scr and scs works and most of the explanations
    show a transistor 'equivalent' circuit. If I wire up the transistor
    equivalent circuit, It consists of a npn and a pnp transistor, Will that be
    a good substitute for the real thing? I am using low power (battery, less
    than 100mA, around 3 to 9volts) DC. I was planning on activating a second
    circuit with a oneshot and needed something to turn it on and stay on till
    power is turned off. I can get 15 pnp transistors at the rat shack for about
    US $2.50.
    Am I better off buying the real thing or should I improvise? It's a onesy
    twosey hobby project.

  5. SCR's of that spec are pretty cheap and I reckon would be better for your
    purpose being a single component.
