Overview

The BD434 is a bipolar made by LGE in a TO-126 package with 3 pins. 1 PNP 1.25W 100uA 22V 375 3MHz 4A 500mV 5V PNP TO-126 Bipolar (BJT) ROHS.

PCBKit's library has its KiCad symbol (Transistor_BJT:BD434, from KiCad's library) and its footprint (Package_TO_SOT_THT:TO-126-3_Vertical, from KiCad's library), ready for a KiCad board. 487 are in stock at JLCPCB (part C19272960). 1 open-source board in 1 repository on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the BD434?

Yes. The symbol is Transistor_BJT:BD434 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 BD434?

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

Where is the BD434 datasheet?

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

Where can I order the BD434?

JLCPCB lists it as part C19272960, with 487 in stock; the sellers' links on this page open their listings.

What can replace the BD434?

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

Which open-source boards use the BD434?

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