I'm rebuilding several old power supplies from the 80's. They are used to power working DAC computers from Optim. The problem is, I can't find the data sheet on the 1N758 diode used for voltage regulation. I can't find the actual diode either. Any one know where I can get either or both??

Thanks for the help

You could try replacing it with the NTE5019A.

My old databook says that it is a 10V 400mW zener diode.

Did you try Google? The first page has lots of links to datasheets.

 

Did you look at the zener diode listing here?:

There are a number of replacements shown in the list.

 

Funny, they are dirt common around here.

Thing is, match the mw dissipation and zeners are pretty interchangeable.
