Is there a KiCad symbol and footprint for the S3M?
Yes. the footprint Diode_SMD:D_SMB, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the S3M?
SMB, with 2 pins. Its footprint is drawn on this page.
Where is the S3M datasheet?
XCH publishes it: the Datasheet link on this page opens it.
Where can I order the S3M?
JLCPCB lists it as part C7435375, with 2,159 in stock; the sellers' links on this page open their listings.
What can replace the S3M?
Parts like it in the library: the US3MB by FUXINSEMI, the S5M by XCH, the RS3MB by PDW and the RS5MB by PDW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
