Is there a KiCad symbol and footprint for the SM03?
Yes. 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 SM03?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the SM03 datasheet?
TECH PUBLIC publishes it: the Datasheet link on this page opens it.
Where can I order the SM03?
JLCPCB lists it as part C3021107, with 2,719 in stock; the sellers' links on this page open their listings.
What can replace the SM03?
Parts like it in the library: the PESD3V3S2UT by Nexperia, the ESDA5V3L-ES by ElecSuper, the PESD3V3S2UT-N by BORN and the SET23A03L02 by Brightking. Check their datasheets: a part that fits the footprint may still differ in its ratings.
