Between A and B you have a Zener diode, that sets that V.

R3 sets Zener current.

Rest of circuit a FW rectifier fed by line and a filter cap on its output.

Suspicious C2 D2 connection not complete as drawn. Should be more like :\

Thanks. Is this a Zener Diode? if not what is it. The drawing on the pcb is not familiar for me.
