Original poster: "Rothman, Aric" <Aric.Rothman-at-Honeywell-dot-com> I have stumbled across some enormous Motorola diodes, made circa the '70s. The P/N is SDA 10011. There each about one foot long. Does anyone have a databook in which these oldies but possibly goodies might be found? I contacted OnSemi (which I believe is Motorola's discretes spin-off) to no avail. Aric
