diode forward volrage

[dorothegreat]

hi guys,

I searched and searched but had no luck in finding what kind of diodes has a forward voltage of 0.18v. The reason for my search is that i asked for 1n34s in our electronic store and purchased some. after sometime i went to a different store and asked for some 1n34s, i notices that it was different from the one i first purchased in the different store, i measured the forward voltages and found out that the first batch i bought has 0.18v forward voltage.  I am wondering now as to what kind of diodes are those (the one with 0.18v). thanks

Highly likely that they're germanium and will work fine in place of a 1N34.

1N34 diodes come in more than one shape.  They don't all look the same.

Schottky diodes also tend to have low forward voltages - often lower than Germanium, afaik?
