Questions

Is there a KiCad symbol and footprint for the DSK14?

Yes. The symbol is Device:D_Schottky and the footprint Diode_SMD:D_SOD-123F, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the DSK14?

SOD-123FL, with 2 pins. Its footprint is drawn on this page.

Where is the DSK14 datasheet?

MDD publishes it: the Datasheet link on this page opens it.

Where can I order the DSK14?

JLCPCB lists it as part C37049, with 305,257 in stock; the sellers' links on this page open their listings.

What can replace the DSK14?

Parts like it in the library: the DSK34 by hongjiacheng, the DSK120 by hongjiacheng, the DSK210 by hongjiacheng and the DSK24 by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the DSK14?

5 boards in 5 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
