2019-01-11 The 1N60P “Germanium” Diode Issue

From FB group

I bought some 1N60P “germanium” diodes and I found they are not germanium, they are Schottky silicon diodes. They do not work like germanium diodes in circuits that depend on the leakage that germanium diodes have. The Schottky or germanium diodes can be checked for reverse leakage and germanium will have less than 1 hundredth of the microamps of leakage that a germanium diode has. I suggest that anyone who recommends these also reminds readers about this issue.

Here is a video on YouTube about how to tell one from the other.
