Questions

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-220, with 3 pins. Its footprint is drawn on this page.

Where is the TIP122 datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the TIP122?

JLCPCB lists it as part C16283, with 47,574 in stock; the sellers' links on this page open their listings.

What can replace the TIP122?

Parts like it in the library: the BDW94C by STMicroelectronics, the TIP120 by STMicroelectronics, the TIP122 by Slkor and the BDW93C by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the TIP122?

86 boards in 71 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
