Does anyone know what is this diode? Help Me?

Hello,

I could not find out what the AG23 LT diode is. Does anyone have an idea? Thanks for help.

I think it's a Fairchild Schottky Barrier Diode.

Look on the "https://www.onsemi.com/products/discretes-drivers/diodes-rectifiers" web index. Usually AG23 would be the factory ID and date with "LT" being the part number.

Maybe 1SMB18AT3 but double check.
