Is there a KiCad symbol and footprint for the TIP122?
Yes. The symbol is Transistor_BJT:TIP122 and the footprint Package_TO_SOT_THT:TO-220-3_Vertical, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TIP122?
TO-220AB, with 3 pins. Its footprint is drawn on this page.
Where is the TIP122 datasheet?
luJing publishes it: the Datasheet link on this page opens it.
Where can I order the TIP122?
JLCPCB lists it as part C49318131, with 615 in stock; the sellers' links on this page open their listings.
What can replace the TIP122?
Parts like it in the library: the TIP122 by ChipNobo, the TIP122 by Cmos, the TIP127 by luJing and the TIP41C by luJing. Check their datasheets: a part that fits the footprint may still differ in its ratings.
