Overview
The 2N3446 is a bipolar made by SPTECH in a TO-3 package with 4 pins. 1 NPN 1.5V 10V 115W 1mA 60 7.5A 80V NPN TO-3 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NPN_1B_2E_3C_4C, from PCBKit's generic symbols) and its footprint (EasyEDA_Cloud:TO-3_L39.4-W26.7-P10.92-BL-CW, from EasyEDA), ready for a KiCad board. 5 are in stock at JLCPCB (part C2907864).

Is there a KiCad symbol and footprint for the 2N3446?
Yes. The symbol is Pinmap_Generic:Q_NPN_1B_2E_3C_4C and the footprint EasyEDA_Cloud:TO-3_L39.4-W26.7-P10.92-BL-CW, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 2N3446?
TO-3, with 4 pins. Its footprint is drawn on this page.
Where is the 2N3446 datasheet?
SPTECH publishes it: the Datasheet link on this page opens it.
Where can I order the 2N3446?
JLCPCB lists it as part C2907864, with 5 in stock; the sellers' links on this page open their listings.
What can replace the 2N3446?
Parts like it in the library: the MJ15004 by SPTECH, the 2N4398 by SPTECH, the 2N5886 by SPTECH and the BUS13A by SPTECH. Check their datasheets: a part that fits the footprint may still differ in its ratings.
