Need help identify diode with marking C911 KV

[Shimra]

Hello, I need help to identify smd bi-directional diode with marking C911 KV on it. There is a manufacturer logo on the diode but I cant trace back the manufacturer. I have tried to find details about this diode, but without success. It is used in a mixer panel from unknown brand but uses a TEAC board no. E903604-00B. However I cannot find datasheets or schematics for that board. I believe that the diode is installed as a TVS diode in the 12V power circuit. See the pictures for details on the board.

99% a TVS; there look to only be one or two that could be on a 12V supply:

The SMD components marking codes database - Starting with 'KV'

(The numeric part is likely a date or batch code).
