Beware of 1N60P!

[bioroids]

Hi!

I got some 1N60P diodes, thinking they were germaniums...
They were not!

Apparently there are some Schottky diodes with the same denomination. I must have bought some of those, because they don't sound any good (as clippers at least, very harsh). I replaced them with some germaniums I had laying around, and harshness was gone!

Good luck

Try them as clippers in series: cathode to the signal, anode to anode, then cathode to ground.

Hi!

I'll try it for sure! Thanks!

They are Germanium, similar to 1N34 but with a lower reverse current.
1N34 100uA, 1N60P 50uA

Here is a data sheet.

Not necessarily:
1N60P Schottky Barrier Rectifier

Doh - you know what, scratch my suggestion.  That should only be done with zeners.  Don't know if it'll work with schottkys, but it wouldn't hurt to try

I saw those too.

Just assumed that if he thought they were germaniums they were probably glass not plastic.

Anyway, I have some 1N60 Germs and have had good results with them as hard clippers. Never tried them in a soft clipping arrangement like a TS though. As hard clippers I didn't think they were harsh at all in fact they were kind of mellow. Probably depends on the circuit.

Hi!

I thougth they were germaniums, but they don't sound like it at all. I know there are 1N60 germaniums, but didn't know that 1N60 schottky existed! (until now).

They look just like 1N4148s, a little bigger, but not at all like the germaniums I bought before (much bigger and transparent glass).

The conclussion is: I should be more explicit when buying components. :oops:

But manufacturers should not repeat codes for different devices! :evil:

Good luck!

I think the problem with the 1N60P, is that when a circuit uses a Ge 1N60, 99% of the time it is because the circuit calls for a low foward voltage drop diode. And since a schottky Si meets that requirement, some 'bright' manufacturer created the 1N60P!!! the only thing the Si 1N60P isn't good for, is stompboxes where you wnat the gradual curve. :x  :cry:
I admit, it would have sucked me in, I would have thought 'Ge in a Plastic case". So thanks for the headsup, guys!
