Overview
The BSN20 is a MOSFET made by KUU in a SOT-23 package with 3 pins. 1 N-channel 1.6V 22pF 4pF 500mA 50V 5Ω@10V 600mW 800nC@10V N-Channel SOT-23 MOSFETs ROHS.
PCBKit's library has its KiCad symbol (Transistor_FET:BSN20, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 922 are in stock at JLCPCB (part C7587867).

Questions
Is there a KiCad symbol and footprint for the BSN20?
Yes. The symbol is Transistor_FET:BSN20 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 BSN20?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the BSN20 datasheet?
KUU publishes it: the Datasheet link on this page opens it.
Where can I order the BSN20?
JLCPCB lists it as part C7587867, with 922 in stock; the sellers' links on this page open their listings.
What can replace the BSN20?
Parts like it in the library: the SI2308A by UMW, the SI2310 by GOODWORK, the AS2324 by AnBon and the LP2309LT1G by Leshan Radio (LRC). Check their datasheets: a part that fits the footprint may still differ in its ratings.
