Overview
The TIP142 is a darlington Transistor made by STMicroelectronics in a TO-247AC-3 package with 3 pins. 1000 100V 10A 125W 1mA 3V 3V 5V NPN TO-247AC-3 Darlington Transistors ROHS.
PCBKit's library has its KiCad symbol (dk_Transistors-Bipolar-BJT-Single:TIP142, from Digikey) and its footprint (digikey-footprints:TO-247-3, from Digikey), ready for a KiCad board. 847 are in stock at JLCPCB (part C31254). 7 open-source boards in 7 repositories on GitHub use it.

Is there a KiCad symbol and footprint for the TIP142?
Yes. The symbol is dk_Transistors-Bipolar-BJT-Single:TIP142 and the footprint digikey-footprints:TO-247-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TIP142?
TO-247AC-3, with 3 pins. Its footprint is drawn on this page.
Where is the TIP142 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the TIP142?
JLCPCB lists it as part C31254, with 847 in stock; the sellers' links on this page open their listings.
What can replace the TIP142?
Parts like it in the library: the TIP142P by SPTECH, the TIP142 by onsemi and the TIP142 by SPTECH. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the TIP142?
7 boards in 7 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
