Is there a KiCad symbol and footprint for the SESM12?
Yes. The symbol is EasyEDA_Cloud:MMBZ27VAL-7-F 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 SESM12?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the SESM12 datasheet?
SEMIWARE publishes it: the Datasheet link on this page opens it.
Where can I order the SESM12?
JLCPCB lists it as part C696628, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SESM12?
Parts like it in the library: the PSM712-LF-T7 by PROTEK, the SM712 by DOWO, the CDSOT23-SM712-ES by ElecSuper and the SM712 by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
