Datasheet wanted for old SCR from RCA

  1. I have got an old SCR/Thyristor in TO220 package with the following
    markings on the package:

    16996
    RCA
    C 7716
    K A G

    I haven't found any data on this device. Has anybody got any info on it,
    or even a pointer to a datasheet?

    Sounds like a "house number". If so, there won't be a published
    datasheet.

    I have looked in my old RCA transistor books (to 1967) and old SK
    replacement series cross reference (1989) for both numbers to no avail.
    Obviously the "K A G" are markings for the thyristor termionals.

    I agree, no sign at all of any 16996 in my old RCA books.
    But 7716 looks like a date code (16th week of 1977), and
    K A G looks like the terminals. I'd suggest figuring out
    the voltage and current ratings from the application, and
    selecting a more modern SCR.

    Thanks,

  5. There isn't an application, as I've found a few of them buried in one of
    my boxes of bits. They possibly were in there for 20 years. I just
    wanted to know if there's a chance to figure out what they are. I'll
    measure them through, I guess...

    Ah, by the way, the 6 could be a G, the printing is a bit ambiguous. But
    I don't expect it helps much...

    Thanks for your help, anyway.
