I pulled a whoops and lost a tiny component I desoldered. Luckily I remember the markings and there are others on the board.
The diode is an SOT-23 package with two identically oriented diodes. The markings were "A4" then a sideways 7 next to that. Not sure what to make of the seven but when I look up an A4 diode, there is some indication it is a schottky, some not.
The diode only functions as a reverse polarity device to protect a driver chip ground. It is in series between ground and the chip, and there is also a parallel 10k resistor. IMO, does not seem like a schottky is needed there.
I am simply going to have to buy another and move on but need to make sure I get something appropriate.
