Questions

Is there a KiCad symbol and footprint for the STN851?

Yes. The symbol is Pinmap_Generic:Q_NPN_1B_2C_3E_4C and the footprint Package_TO_SOT_SMD:SOT-223, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the STN851?

SOT-223, with 4 pins. Its footprint is drawn on this page.

Where is the STN851 datasheet?

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

Where can I order the STN851?

JLCPCB lists it as part C133359, with 0 in stock; the sellers' links on this page open their listings.

What can replace the STN851?

Parts like it in the library: the 2STN1550 by STMicroelectronics, the NSS60600MZ4 by onsemi, the FZT951TA by Diodes Incorporated and the ZX5T1951GTA by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the STN851?

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