Help! I have a Really Weird Part


Recommended Posts

When the black band was connected to the resistor, it would not conduct. Well, until there was a lot of DC voltage applied, then it seemed to break down just a bit.  It definitely has the characteristics of a Shockley Diode - that was a huge help. The work around was a zener diode and an SCR. The Zener connected to the gate and anode. Once the SCR gate got enough current, it was on and the Zener was shorted.

One other question: where can I order one (or many) of these and/or do companies still sell them?

Thanks again for the help.
