The ident on the pcb is D35 & a diode symbol,showing the cathode identified by a band. Place the multimeter knob in voltage mode. If so, the part number for the diode is B14A, and a manufacturer's part number would probably be longer and include the B14 designation. They use instead a marking code typically composed of a combination of 2 or 3 letters or digits. Scribd is the world's largest social reading and publishing site. I have a surface mount diode, glass, SOD 80 type package,from a Keyence microcontroller, which has gone short circuit.

SMD/SMT resistors. Generally diodes are used as reverse polarity protector and transient protector.
