Overview
The MMFTN123 is a MOSFET made by DIOTEC in a SOT-23-3(TO-236-3) package with 3 pins. -55℃~+150℃ 1 N-channel 100V 10Ω@4.5V 170mA 2V 3.4pF 360mW 73pF 7pF N-Channel SOT-23-3(TO-236-3) 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-23-3, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3280180).

Questions
Is there a KiCad symbol and footprint for the MMFTN123?
Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2S_3D and the footprint Package_TO_SOT_SMD:SOT-23-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the MMFTN123?
SOT-23-3(TO-236-3), with 3 pins. Its footprint is drawn on this page.
Where is the MMFTN123 datasheet?
DIOTEC publishes it: the Datasheet link on this page opens it.
Where can I order the MMFTN123?
JLCPCB lists it as part C3280180, with 0 in stock; the sellers' links on this page open their listings.
What can replace the MMFTN123?
Parts like it in the library: the SI2301 by YONGYUTAI, the AO3400A by ElecSuper, the AO3400-HXY by HXY MOSFET and the AP2317A by ALLPOWER. Check their datasheets: a part that fits the footprint may still differ in its ratings.
