| This -OI- is printed on a pcb under a diode. Zener ? |

Could it be a - stylized - indication of polarity, O = anode, | = kathode?

| There are also standard symbols for diode and zener on the pcb, it is Sony. |

Isn't that a symbol for a current source diode (essentially a JFET with the gate and source leads internally connected)?

| yes that's a current source "diode" symbol..... what's the part number on the component? |

| Hmmm it looks like a current source diode, it is in series with a zener between V- and ground. |
