Overview

The KSP43BU is a bipolar made by onsemi in a TO-92-3 package with 3 pins. 100nA 200V 40 500mA 500mV 50MHz 625mW NPN TO-92-3 Bipolar (BJT) ROHS.

PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NPN_1E_2B_3C, from PCBKit's generic symbols) and its footprint (EasyEDA_Cloud:TO-92-3_L4.9-W3.7-P1.27-L, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C896750). 4 open-source boards in 2 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the KSP43BU?

Yes. The symbol is Pinmap_Generic:Q_NPN_1E_2B_3C and the footprint EasyEDA_Cloud:TO-92-3_L4.9-W3.7-P1.27-L, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the KSP43BU?

TO-92-3, with 3 pins. Its footprint is drawn on this page.

Where is the KSP43BU datasheet?

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

Where can I order the KSP43BU?

JLCPCB lists it as part C896750, with 0 in stock; the sellers' links on this page open their listings.

What can replace the KSP43BU?

Parts like it in the library: the KSP2907ABU by onsemi, the KSP42BU by onsemi, the ZTX455STZ by Diodes Incorporated and the BC33725BU by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the KSP43BU?

4 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
