Overview
The SS24K is a schottky Barrier Diode made by TDD in a SMA package with 2 pins. 2A 40V 500uA@40V 550mV@2A Standalone SMA Schottky Diodes ROHS.
PCBKit's library has its KiCad symbol (Device:D_Schottky, from KiCad's library) and its footprint (Diode_SMD:D_SMA, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C2944426). 1 open-source board in 1 repository on GitHub use it.

Is there a KiCad symbol and footprint for the SS24K?
Yes. The symbol is Device:D_Schottky and the footprint Diode_SMD:D_SMA, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SS24K?
SMA, with 2 pins. Its footprint is drawn on this page.
Where is the SS24K datasheet?
TDD publishes it: the Datasheet link on this page opens it.
Where can I order the SS24K?
JLCPCB lists it as part C2944426, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SS24K?
Parts like it in the library: the SS24 by MDD, the SS24 by TDD, the SK34A-LTP by Micro Commercial Components and the SS34 by TDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SS24K?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
