Questions

Is there a KiCad symbol and footprint for the SM03C?

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 SM03C?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the SM03C datasheet?

Slkor publishes it: the Datasheet link on this page opens it.

Where can I order the SM03C?

JLCPCB lists it as part C5122534, with 11 in stock; the sellers' links on this page open their listings.

What can replace the SM03C?

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.
