Is there a KiCad symbol and footprint for the S3MB?
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 S3MB?
SMB, with 5 pins. Its footprint is drawn on this page.
Where is the S3MB datasheet?
RS publishes it: the Datasheet link on this page opens it.
Where can I order the S3MB?
JLCPCB lists it as part C19103844, with 651 in stock; the sellers' links on this page open their listings.
What can replace the S3MB?
Parts like it in the library: the US3MB by FUXINSEMI, the S3M by XCH, the S5M by XCH and the RS3MB by PDW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
