Is there a KiCad symbol and footprint for the SMF170CA?
Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SOD-123, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMF170CA?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the SMF170CA datasheet?
FMS publishes it: the Datasheet link on this page opens it.
Where can I order the SMF170CA?
JLCPCB lists it as part C266758, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMF170CA?
Parts like it in the library: the ATV02W171-HF by Comchip, the ATV02W171B-HF by Comchip, the TV02W171-G by Comchip and the TV02W171-HF by Comchip. Check their datasheets: a part that fits the footprint may still differ in its ratings.
