Overview

The TIP125 is a darlington Transistor made by STMicroelectronics in a TO-220 package with 3 pins. 1000 2.5V 200uA 5A 5V 60V 65W PNP TO-220 Darlington Transistors ROHS.

PCBKit's library has its KiCad symbol (Transistor_BJT:TIP125, from KiCad's library) and its footprint (Package_TO_SOT_THT:TO-220-3_Vertical, from KiCad's library), ready for a KiCad board. 48 are in stock at JLCPCB (part C2832846). 5 open-source boards in 5 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the TIP125?

Yes. The symbol is Transistor_BJT:TIP125 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 TIP125?

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

Where is the TIP125 datasheet?

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

Where can I order the TIP125?

JLCPCB lists it as part C2832846, with 48 in stock; the sellers' links on this page open their listings.

What can replace the TIP125?

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

Which open-source boards use the TIP125?

5 boards in 5 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
