Is there a KiCad symbol and footprint for the SMF43CA?
Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SOD-123F, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMF43CA?
SOD-123FL, with 2 pins. Its footprint is drawn on this page.
Where is the SMF43CA datasheet?
Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.
Where can I order the SMF43CA?
JLCPCB lists it as part C1509111, with 1,130 in stock; the sellers' links on this page open their listings.
What can replace the SMF43CA?
Parts like it in the library: the SMFJ43A by BORN, the SMF43CA by FOSAN, the SMF43CA by MSKSEMI and the SMF43CA by OTW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
