Overview

The BD441 is a bipolar made by Jiangsu Changjing Electronics Technology (CJ) in a TO-126 package with 3 pins. 1 NPN 1.25W 100uA 3MHz 4A 5V 800mV 80V NPN TO-126 Bipolar (BJT) ROHS.

PCBKit's library has its KiCad symbol (Transistor_BJT:BD441, from KiCad's library) and its footprint (Package_TO_SOT_THT:TO-126-3_Vertical, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C2961236).

Questions

Is there a KiCad symbol and footprint for the BD441?

Yes. The symbol is Transistor_BJT:BD441 and the footprint Package_TO_SOT_THT:TO-126-3_Vertical, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BD441?

TO-126, with 3 pins. Its footprint is drawn on this page.

Where is the BD441 datasheet?

Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.

Where can I order the BD441?

JLCPCB lists it as part C2961236, with 0 in stock; the sellers' links on this page open their listings.

What can replace the BD441?

Parts like it in the library: the BD434 by LGE, the BD441 by onsemi, the BD438 by STMicroelectronics and the BD437 by YFW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
