Hello, I have a few devices which someone guessed might be Germanium diodes. I'm not sure though. They have a forward resistance of about 630 K Ohms. They have no markings but a dark spot on one end of their red oval shape. See attached pic. Thanks.
Thanks. Is there any way to easily determine more of its specs? I tried using it in a RF signal detector but it's resistance is so high it didn't work.
