Seeking Syntron S4005 Diode Data
(OP)
Can anyone here point me toward a Data Sheet, or info related to the operating characteristics
of an old Syntron S4005 Diode? It's in a DO-8 Package with a date code that appears to be from the 29th week of 1964.
Any help... will be a big help.
Photo attached for reference:
Thanks in advance.

Half full - Half empty? I don't mind. It's what in it that counts.

Also, OP mentioned attached photo. None attached nor linked. It would be useful to confirm the package type.
RE: Seeking Syntron S4005 Diode Data
The diode is one of 4 making up a bridge rectifier.

If the piece of equipment is from 1964 to say 1970, I would guess that the diode is nothing special. In the worst case you could replace all four.
Looking at Syntron’s S-series numbering, SXXX5 might be a 50 Volt diode, this coming from a S5105 data sheet. An RSXXX indicates a reverse polarity.

It appears the S4005 is/was a Syntron catalog number with the "S" denoting standard polarity direction, the "40" indicating the manufacturer's product Series Number,
and the "05" meaning the Peak Reverse Voltage as 50.
(Still don't know what the current capacity of the device is though.)
In searching out the Syntron Company; I found it interesting that the Coors name, (as many of us may know as a beer beverage company) and their identical "Coors" font...
was at one time associated with ceramics used to package electronic components.

Coors ceramics are still a big deal. They have a lot of experience with alumina.
RE: Seeking Syntron S4005 Diode Data
The bottom line has to be, "What does the diode in question actually do? " If it's really nothing more than a bridge rectifier, then some sleuthing into the circuit performance will dictate the amount of current the device is required to handle. Is this bridge after a step-down transformer? Otherwise, the 50V rating seems a trifle low.
