This is a B113 module with green board and a blue plastic extraction handle attached by two rivets. The component side is marked with three inspection stamps, two round and one square; "FLIP CHIP" can be read faintly through the board between the rivets. Throughout the green substrate the letters "NP" are marked in red. "DIODE GATE B113C" is stamped on the solder side.
