Is there a KiCad symbol and footprint for the SESMC18?
Yes. The symbol is EasyEDA_Cloud:SESMC18 and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SESMC18?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the SESMC18 datasheet?
SEMIWARE publishes it: the Datasheet link on this page opens it.
Where can I order the SESMC18?
JLCPCB lists it as part C696633, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SESMC18?
Parts like it in the library: the SM18C by MDD, the SM18 by Wild Goose, the BST23C182V by BORN and the SM18 by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
