Hey,

I am looking for some specs for this item 1N4735AT9. If anyone knows where to find a datasheet or if this item is even still in production. Thanks

 

First hit with Google - http://www.datasheetcatalog.com/datasheets_pdf/1/N/4/7/1N4735.shtml

If that zener is not in production, any zener with the same voltage and dissipation should work.

 

Hello,

From the list in the link of psot #2 of this thread:

You can see it is a 6.2 Volts / 1 Watt zener.
A BZX85C6V2 would be a replacement.
