Is there a KiCad symbol and footprint for the SMA4F16A?
Yes. The symbol is Device:D_TVS and the footprint EasyEDA_Cloud:SMA_L4.3-W2.6-LS5.2-RD, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMA4F16A?
SMA-flat, with 2 pins. Its footprint is drawn on this page.
Where is the SMA4F16A datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the SMA4F16A?
JLCPCB lists it as part C1973832, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMA4F16A?
Parts like it in the library: the P6SMAJ16ADF by Diodes Incorporated, the SMA4F15A by STMicroelectronics, the SMAJ16A-QH by Bourns and the SMAJ16CA-QH by Bourns. Check their datasheets: a part that fits the footprint may still differ in its ratings.
