Overview
The S3J is a diodes General Purpose made by TWGMC in a SMA(DO-214AC) package with 2 pins. -55℃~+150℃ 1.1V@3A 3A 5uA 600V Standalone SMA(DO-214AC) Diodes - General Purpose ROHS.
PCBKit's library has its KiCad symbol (Device:D, from KiCad's library) and its footprint (Diode_SMD:D_SMA, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C4154418).

Is there a KiCad symbol and footprint for the S3J?
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 S3J?
SMA(DO-214AC), with 2 pins. Its footprint is drawn on this page.
Where is the S3J datasheet?
TWGMC publishes it: the Datasheet link on this page opens it.
Where can I order the S3J?
JLCPCB lists it as part C4154418, with 0 in stock; the sellers' links on this page open their listings.
What can replace the S3J?
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.
