I have a spare DC mobo here and took some measures on D604 with a multimeter.

I found that is a double Schottky diode, here's the datasheet of it:

I also found a place where you can buy it:

Anyway, this diode is part of the FAN tachometer circuit, it's possible to bypass it by using a jumper like you did, but of course the DC will lose its thermal protection, so it's better do the right thing.
