Overview
The SM712 is an ESD And Surge Protection made by Leiditech in a SOT-23 package with 3 pins. 10V、12V、17V、20V、26V 10uA 400W@8/20us 45pF 7.5V、13.3V 7V、12V ESD IEC 61000-4-2、IEC 61000-4-5、IEC 61000-4-4 SOT-23 ESD and Surge Protection (TVS/ESD) ROHS.
PCBKit's library has its KiCad symbol (Diodes:SM712, from CERN's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C384877).

Is there a KiCad symbol and footprint for the SM712?
Yes. The symbol is Diodes:SM712 and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SM712?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the SM712 datasheet?
Leiditech publishes it: the Datasheet link on this page opens it.
Where can I order the SM712?
JLCPCB lists it as part C384877, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SM712?
Parts like it in the library: the SM712 by hongjiacheng, the PSM712-LF-T7 by PROTEK, the PESD1CAN by Nexperia and the NUP2105L by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
