Default Help Identifying Diode for Macbook Air a1466 with 820-00165 board

While reviewing the a1466 820-00165 board schematics, I came across a diode that I need to identify. The part in question is labeled D2920 (NSR1020MW2T1G), but my problem is that the schematic has the icon for a Zener Diode, but when I look up the part number, I only get results for a Schottky Diode. I don't have much experience with technical schematics at all and this part just so happens to be missing from the board I am trying to fix so I need to get my hands on the correct replacement part.

I have attached both the schematic portion in question and a screenshot of the part that should be on my board.

Anyone have any experience and know what kind of diode should be placed here? Is it Zener or Schottky?

Stick with the part number in the schematic and ignore the symbol.

This one is from onsemi and is a schottky diode.

It is defective on your board?

Remove off your board and check with a meter in diode mode.

It will be Schottky diode, as it's in a classic config for a boost converter. Fast recovery, low forward voltage drop etc.
