Hello,
Can anyone point me in the right direction regarding this diode?: (pic 1)
The rings seem to be red-red-'something' (first red band is the cathode), where 'something' looks either greenish or bluish depending on the light...
It is removed from a vintage video card that I'm repairing (Asus GeForce 2 GTS), where it failed in a half-shorted state, leading to the burning of R22 from the schematic below (pasted here from the US3007 datasheet). Problem is that the datasheet doesn't mention anything about such a diode (I've added it in red

to correspond with the implementation on the Asus board): (pic 2)
The board works just fine after removing the diode and replacing the burnt resistor, and the Nvidia reference implementation doesn't use the diode and also does away with the 10 ohm resistor, but one has to wonder, did Asus install the diode for no reason? (pic 3)
