Questions

Is there a KiCad symbol and footprint for the S1B?

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 S1B?

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

Where is the S1B datasheet?

onsemi publishes it: the Datasheet link on this page opens it.

Where can I order the S1B?

JLCPCB lists it as part C96324, with 5,791 in stock; the sellers' links on this page open their listings.

What can replace the S1B?

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.
