Overview
The BSS84 is a MOSFET made by Jiangsu Changjing Electronics Technology (CJ) in a SOT-23 package with 3 pins. 1 P-Channel 10pF 130mA 225mW 2V 30pF 50V P-Channel SOT-23 MOSFETs ROHS.
PCBKit's library has its KiCad symbol (Transistor_FET:BSS84, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 118,165 are in stock at JLCPCB (part C114481).

Questions
Is there a KiCad symbol and footprint for the BSS84?
Yes. The symbol is Transistor_FET:BSS84 and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BSS84?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the BSS84 datasheet?
Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.
Where can I order the BSS84?
JLCPCB lists it as part C114481, with 118,165 in stock; the sellers' links on this page open their listings.
What can replace the BSS84?
Parts like it in the library: the 2N7002K by MDD, the 2N7002K by hongjiacheng, the BSS138 by Diodes Incorporated and the BSS138 by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
