Overview
The AS3422 is a MOSFET made by AnBon in a SOT-23 package with 3 pins. -55℃~+150℃ 1 N-channel 1.25W 2.1A 200mΩ@2.5V 214pF 2V 55V SOT-23 MOSFETs ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NMOS_1G_2S_3D, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C232283).

Questions
Is there a KiCad symbol and footprint for the AS3422?
Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2S_3D 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 AS3422?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the AS3422 datasheet?
AnBon publishes it: the Datasheet link on this page opens it.
Where can I order the AS3422?
JLCPCB lists it as part C232283, with 0 in stock; the sellers' links on this page open their listings.
What can replace the AS3422?
Parts like it in the library: the SQ2361CEES-T1_GE3 by Vishay Intertechnology, the SI2392ADS-T1-GE3 by ElecSuper, the LJ2294B by ALJ and the RC3P06 by RealChip. Check their datasheets: a part that fits the footprint may still differ in its ratings.
