Is there a KiCad symbol and footprint for the SM15?
Yes. The symbol is EasyEDA_Cloud:SM03 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 SM15?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the SM15 datasheet?
Leiditech publishes it: the Datasheet link on this page opens it.
Where can I order the SM15?
JLCPCB lists it as part C384874, with 2 in stock; the sellers' links on this page open their listings.
What can replace the SM15?
Parts like it in the library: the PESD15VL2BT by TECH PUBLIC, the PESD15VL2BT-N by BORN, the BST23A152V by BORN and the PESD15VS2UAT by Nexperia. Check their datasheets: a part that fits the footprint may still differ in its ratings.
