There are quite a few on the board.
You could measure them and a diode should normaly be quite obious as it measure +/-0,6V in one direction.

Edit: Google points to a few datasheets of zener diodes if you look for '16B SMD'

10uF 16V tantalum caps perhaps? 106 is very likely 10,000,000pF in capacitor markings, diodes generally have letters to start the part number
