Is there a KiCad symbol and footprint for the BCX71J?
Yes. the footprint Package_TO_SOT_SMD:SOT-23-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BCX71J?
SOT-23-3, with 5 pins. Its footprint is drawn on this page.
Where is the BCX71J datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the BCX71J?
JLCPCB lists it as part C3199935, with 0 in stock; the sellers' links on this page open their listings.
