Fish-in-a-Barrel/Nixie
This is my Nixie clock project. It was created as an excuse to learn more about electronics and it touches on power circuits, microcontrollers, serial communications, and more.

The SMD220PL-TP is a schottky Diode made by Micro Commercial Components in a SOD-123FL package with 2 pins. -65℃~+150℃ 1 Independent 10uA@200V 200V 2A 50A 900mV@2A SOD-123FL Schottky Diodes ROHS.
PCBKit's library has its KiCad symbol (Device:D_Schottky, from KiCad's library) and its footprint (Diode_SMD:D_SOD-123F, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C725476). 2 open-source boards in 2 repositories on GitHub use it.

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.
SOD-123FL, with 2 pins. Its footprint is drawn on this page.
Micro Commercial Components publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C725476, with 0 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the DSK320 by hongjiacheng, the DSK220 by hongjiacheng, the RSX068MP2STR by ROHM Semiconductor and the DSS320 by BORN. Check their datasheets: a part that fits the footprint may still differ in its ratings.
2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
