Is there a KiCad symbol and footprint for the K090SD?
Yes. The symbol is Device:D 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 K090SD?
SOD-123FL, with 2 pins. Its footprint is drawn on this page.
Where can I order the K090SD?
JLCPCB lists it as part C56192719, with 100 in stock; the sellers' links on this page open their listings.
What can replace the K090SD?
Parts like it in the library: the DB3W by Shandong Jingdao Microelectronics, the DB3W by FOSAN, the SODDB3 by MDD and the DB3W by XCH. Check their datasheets: a part that fits the footprint may still differ in its ratings.
