ID this SMD?

[Audiorepair]

Hi,

this is a synth keyboard scanning circuit with these 5 pin devices connected to each keys' 2 pads, only there is no service manual for this and I don't know what they are, they are normally not present on such key PCB's.

The onboard scanning IC is this one:

Normally these keyframes are scanned from the CPU side, not locally like this one.
It's a Korg MS20 Mini.


Cheers.

You can check this database - go to "G9"

https://smd.yooneed.one/

I don't know what the last symbol is there, but it might just be a diode or transistor. All five pins might not be used

G9? so baffled by the last letter

SOT-353    NPN digital transistors

as on https://www.s-manuals.com/smd/g9

Ah, excellent, thanks to all.
Drew a blank at G9 myself, not in the SMD codebook.

Farnell even have umg9n in stock.

Thanks, I did Google another source and that had no G9's either.

I shall make this my primary source in future then.
