I found this just a few minutes ago, on a web site.
The diodes are in a small 3-leaded SM package. Looking down at the
package with it oriented so that the single lead is on top, the
cathode is the top tab and the anode is the left tab on the bottom.

It looks like the bottom right out of the two is not used.
Wonder if anyone can confirm the above?

That's consistent with what I see in the data sheets for the
surface-mount (SOT-23) switching diodes of type 914 and 4148.
