Is there a KiCad symbol and footprint for the SMB6F188A?
Yes. The symbol is Device:D_TVS and the footprint EasyEDA_Cloud:SMB_L4.3-W3.6-LS5.4-RD, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMB6F188A?
SMB-flat, with 2 pins. Its footprint is drawn on this page.
Where is the SMB6F188A datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the SMB6F188A?
JLCPCB lists it as part C1977013, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMB6F188A?
Parts like it in the library: the SMAJ188A M2G by Taiwan Semiconductor, the SMAJ188A R3G by Taiwan Semiconductor, the SMAJ188AHM2G by Taiwan Semiconductor and the SMAJ188AHR3G by Taiwan Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
