Overview

The TIP41A is a bipolar made by SPTECH in a TO-220C package with 3 pins. 1 NPN 1.5V 3MHz 400uA 5V 60V 65W 6A 75 NPN Standalone TO-220C Bipolar (BJT) ROHS.

PCBKit's library has its KiCad symbol (Transistor_BJT:TIP41A, from KiCad's library) and its footprint (Package_TO_SOT_THT:TO-220-3_Vertical, from KiCad's library), ready for a KiCad board. 28 are in stock at JLCPCB (part C2907633). 6 open-source boards in 6 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the TIP41A?

Yes. The symbol is Transistor_BJT:TIP41A 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 TIP41A?

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

Where is the TIP41A datasheet?

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

Where can I order the TIP41A?

JLCPCB lists it as part C2907633, with 28 in stock; the sellers' links on this page open their listings.

What can replace the TIP41A?

Parts like it in the library: the TIP42C by STMicroelectronics, the TIP42C by JSMSEMI, the TIP41C by STMicroelectronics and the TIP41C by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the TIP41A?

6 boards in 6 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
