Overview
The TIP122D is a darlington Transistor made by FeiHong in a TO-220 package with 3 pins. 1000 100V 100uA 3V 65W 8A NPN TO-220 Darlington Transistors ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:TIP122D, from EasyEDA) and its footprint (EasyEDA_Cloud:TO-220-3_L10.0-W4.5-P2.54-L-1, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C438752).

Is there a KiCad symbol and footprint for the TIP122D?
Yes. The symbol is EasyEDA_Cloud:TIP122D and the footprint EasyEDA_Cloud:TO-220-3_L10.0-W4.5-P2.54-L-1, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TIP122D?
TO-220, with 3 pins. Its footprint is drawn on this page.
Where is the TIP122D datasheet?
FeiHong publishes it: the Datasheet link on this page opens it.
Where can I order the TIP122D?
JLCPCB lists it as part C438752, with 0 in stock; the sellers' links on this page open their listings.
What can replace the TIP122D?
Parts like it in the library: the TIP127C by FeiHong and the BDX34BG by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
