Overview
The AO3402 is a MOSFET made by MDD in a SOT-23 package with 3 pins. -50℃~+150℃ 1 N-channel 1.5W 240pF 28mΩ@10V 3.1nC@15V 30V 30pF 5A 800mV 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 C427384).

Questions
Is there a KiCad symbol and footprint for the AO3402?
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 AO3402?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the AO3402 datasheet?
MDD publishes it: the Datasheet link on this page opens it.
Where can I order the AO3402?
JLCPCB lists it as part C427384, with 0 in stock; the sellers' links on this page open their listings.
What can replace the AO3402?
Parts like it in the library: the AP40P05 by ALLPOWER, the 5N10-MS by MSKSEMI, the MDD3400 by MDD and the SI2318CDS by Vishay Intertechnology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
