I'm thinking germanium too, but even then, google seems to believe there isn't a standard bar code.
They look an awful lot like theses guys:

I still have to test the voltage.

My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.
Not as dumb as yesterday, but stupider than tomorrow!

Re: What is this IC?
I had to have a quickie look. Used 2 meters on diode mode and got these readings:
Is the top one measuring resistance (339)?
And is the bottom one measuring voltage (0.282)?

Re: What is this IC?
These used to be the AM detector diode commonly used in transistor radios in the 80's and early 90's

Almost there

Re: What is this IC?
Obviously...!
Youngers I am sure do not know about AM demodulation through germanium diodes!
Once, at the age of 10-11, I made the first AM radio with such a diode, and an old telephone earpiece that was connected to a vertical metal waterpipe. It was amazing experience to here the local radio station with this!!!
