Overview
The S2M is a diodes General Purpose made by YFSEMI in a SMB(DO-214AA) package with 2 pins. -55℃~+150℃ 1 Independent 1.1V@2A 1kV 2A 50A 5uA@1kV SMB(DO-214AA) Diodes - General Purpose ROHS.
PCBKit's library has its KiCad symbol (Device:D, from KiCad's library) and its footprint (Diode_SMD:D_SMB, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C2887438).

Is there a KiCad symbol and footprint for the S2M?
Yes. The symbol is Device:D and 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 S2M?
SMB(DO-214AA), with 2 pins. Its footprint is drawn on this page.
Where is the S2M datasheet?
YFSEMI publishes it: the Datasheet link on this page opens it.
Where can I order the S2M?
JLCPCB lists it as part C2887438, with 0 in stock; the sellers' links on this page open their listings.
What can replace the S2M?
Parts like it in the library: the S3MB by hongjiacheng, the S3MB by MDD, the S2M by MDD and the S5MB by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
