Is there a KiCad symbol and footprint for the TDM3478?
Yes. The symbol is Pinmap_Generic:Q_NMOS_0S_1S_2S_3S_4G_5D_6D_7D_8D_9D and the footprint EasyEDA_Cloud:DFN-8_L3.0-W3.0-P0.65-BL-A, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TDM3478?
DFN-8(3x3), with 10 pins. Its footprint is drawn on this page.
Where is the TDM3478 datasheet?
Techcode publishes it: the Datasheet link on this page opens it.
Where can I order the TDM3478?
JLCPCB lists it as part C105508, with 7,807 in stock; the sellers' links on this page open their listings.
What can replace the TDM3478?
Parts like it in the library: the AON7418-VB by VBsemi Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
