Overview
The SD12LC is an ESD And Surge Protection made by SMC in a SOD-323 package with 2 pins. -55℃~+150℃ 11A@8/20us 12V 13.3V 1uA 28.6V 350W 5pF TVS Unidirectional SOD-323 ESD and Surge Protection (TVS/ESD) ROHS.
PCBKit's library has its KiCad symbol (Device:D_TVS, from KiCad's library) and its footprint (Diode_SMD:D_SOD-323, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3711004).

Is there a KiCad symbol and footprint for the SD12LC?
Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SOD-323, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SD12LC?
SOD-323, with 2 pins. Its footprint is drawn on this page.
Where is the SD12LC datasheet?
SMC publishes it: the Datasheet link on this page opens it.
Where can I order the SD12LC?
JLCPCB lists it as part C3711004, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SD12LC?
Parts like it in the library: the H5VLD3B by hongjiacheng, the PESD1LIN by UMW, the PESD5V0S1BA by HXY MOSFET and the PESD5V0S1BA by TECH PUBLIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
