Overview

The BD440 is a bipolar made by Jiangsu Changjing Electronics Technology (CJ) in a TO-126 package with 3 pins. -55℃~+150℃ 1 PNP 1.25W 100uA 3MHz 475 4A 5V 60V 800mV PNP TO-126 Bipolar (BJT) ROHS.

PCBKit's library has its KiCad symbol (Transistor_BJT:BD440, 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 C2992035). 1 open-source board in 1 repository on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the BD440?

Yes. The symbol is Transistor_BJT:BD440 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 BD440?

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

Where is the BD440 datasheet?

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

Where can I order the BD440?

JLCPCB lists it as part C2992035, with 0 in stock; the sellers' links on this page open their listings.

What can replace the BD440?

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.

Which open-source boards use the BD440?

1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
