Questions

Is there a KiCad symbol and footprint for the S1M?

Yes. The symbol is Device:D and the footprint Diode_SMD:D_SMA, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the S1M?

SMA(DO-214AC), with 2 pins. Its footprint is drawn on this page.

Where is the S1M datasheet?

Diodes Incorporated publishes it: the Datasheet link on this page opens it.

Where can I order the S1M?

JLCPCB lists it as part C155378, with 133,148 in stock; the sellers' links on this page open their listings.

What can replace the S1M?

Parts like it in the library: the M7 by MDD, the M7 by hongjiacheng, the M7 by MSKSEMI and the M7 by Yangzhou Yangjie Electronic Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the S1M?

36 boards in 29 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
