Germanium Diode Options

Postby soupbone » 17 May 2014, 09:33

I like using Germanium Diodes in certain circuits.The only one's I've used are the common 1N34a.I want to find a different Germanium that has a lot of the same characteristics as the 1N34a.Been looking at some datasheets,and the 1N270 looks like a good candidate.Is there any others I should check in to?

I 've got a handful of 1n60 ge diodes, but never tried them in anything. Just read somewhere, they were good in od circuits...

Sweet!I actually bought some 1N60's from my local electronics shop,but they looked like they were from the 1970's.lol Everyone of them when I bent the leads just crumbled because they were so old.Do anybody make the 1N60 anymore?Thanks!

They are only slightly less common than 1n34a. Both are more common that 1n270 in my experience. !n34a and 1n60 are pretty interchangeable.

Small Bear has them of course. They can all pop up on websites. Tayda has them but it is a good chance they are merely workalikes.

mklec is a new vendor. http://mklec.com/components/diodes/germanium-diodes they have 1n34a. good price too

IIRC 1N34A and 1N60 have substantially different V thresholds. 1N34As I've tested at 450 mV to 650 mV. 1N60s and 1N270s always seem to fall around 350. The difference in threshold affects both volume and the characteristic of the distortion, as the lower your threshold goes, the more compressed your signal becomes.

So,in your opinion do you think a 1n34a would work better in a circuit like ds-1 or sd-1 for example,would be better than the others you named?

Wow,Mammoth Electronics in my home state of Oklahoma have 1N270's and 1N60's!I guess you learn somethin' every day.lol
