Hi all.
I need to identify a diode, DO-4 package, the printed data is: (Siemens) D663-AG S3430

I want to use it in a bridge rectifier, but I forgot the specs, it's a diode made by 1982.
I have some units from my junkbox.
But I can't get the data in the web...
Regards.

Dear Irving, thank you so much for the information!
I really appreciate it.
But I see that the diode does not work for me in this project. I need to rectify 100 amps. .
Maybe putting diodes in parallel. I will see.
Best Regards.
