Overview
The TKMN3400A is a MOSFET made by CTK in a SOT-23 package with 3 pins. SOT-23 MOSFETs ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:DMN2058U-13, from EasyEDA) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C56374660).
