Overview
The BL3400 is a MOSFET made by Galaxy Microelectronics in a SOT-23 package with 3 pins. -55℃~+150℃ 1 N-channel 1.4V 1.4W 13nC@4.5V 30V 32mΩ@4.5V 5.7A 65pF 88pF N-Channel 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. 2,872 are in stock at JLCPCB (part C21882577).

Questions
Is there a KiCad symbol and footprint for the BL3400?
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 BL3400?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the BL3400 datasheet?
Galaxy Microelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the BL3400?
JLCPCB lists it as part C21882577, with 2,872 in stock; the sellers' links on this page open their listings.
What can replace the BL3400?
Parts like it in the library: the 6P03 by GOODWORK, the QN3400S by QNH, the DMN3404L-7-VB by VBsemi Elec and the AO3400 by Foshan Blue Rocket Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
