Overview
The TDM3508 is a MOSFET made by Techcode Semicon in a TO-252 package with 3 pins. 1 N-channel 1.1nF 12mΩ@4.5V 2.5V 30V 39pF 5.8nC@4.5V 50W 68A N-Channel TO-252 MOSFETs ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NMOS_1G_2D_3S, from PCBKit's generic symbols) and its footprint (EasyEDA_Cloud:TO-252-3_L6.5-W5.8-P4.58-BR, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C380225).

Questions
Is there a KiCad symbol and footprint for the TDM3508?
Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2D_3S and the footprint EasyEDA_Cloud:TO-252-3_L6.5-W5.8-P4.58-BR, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TDM3508?
TO-252, with 3 pins. Its footprint is drawn on this page.
Where is the TDM3508 datasheet?
Techcode Semicon publishes it: the Datasheet link on this page opens it.
Where can I order the TDM3508?
JLCPCB lists it as part C380225, with 0 in stock; the sellers' links on this page open their listings.
What can replace the TDM3508?
Parts like it in the library: the AP120N03K by ALLPOWER, the VS8068AD by Vergiga, the VSD004N03MS by Vergiga and the VSD007N06MS by Vergiga. Check their datasheets: a part that fits the footprint may still differ in its ratings.
