How old is the board the component is on?

Could it be a General Instruments part?

Are you sure it's a diode?

Can you take a picture with surrounding components, and, an idea of size?

Additional GI RH13 9344 diode information

I believe the diodes are 1980 era. Ohm meter measurements indicate they are silicon diodes. They have the same dimensions and look of the 1N4001 series diodes (https://www.onsemi.com/pdf/datasheet/1n4001-d.pdf), which are rated at one amp and various voltages. See attached picture.

From my memory the 9344 usually relates to the manufacturers identifier number rather than writing the name eg TI, Westinghouse etc.

There is a listing on ebay for a Motorolla diode RH13 but unfortunately nil stock

Or sometimes the 9344 number is a date code where the part was produced in the 44th week of 1993.

Thanks for the help. With your help and some additional research, the markings appear to mean the following.

GI is the manufacturer, General Instruments.

RH13 is the part number. I could not find any spec sheets, but it seems to be a 1A,600V silicon diode in a DO-41 case.

9344 is the date code, 44th week of 1993.

According to Galco the NTE116 might be an equivalent alternative

It may be a lot easier to verify how the diode is connected, and analyze its application by doing some measurements around the area where it was connected....

Typically looking at the surrounding circuits will give a clue what the diode is being used for and therefore can expect how a diode parameters will serve to satisfy the function.

If diode identification fails, consider substitution as the solution.. Good luck!
