Questions
Is there a KiCad symbol and footprint for the TDA7850?
Yes. The symbol is EasyEDA_Cloud:TDA7850 and the footprint EasyEDA_Cloud:FLEXIWATT25-TH_25P-L29.3-W4.6-P1.00, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TDA7850?
FLEXIWATT-25, with 25 pins. Its footprint is drawn on this page.
Where is the TDA7850 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the TDA7850?
JLCPCB lists it as part C91679, with 10 in stock; the sellers' links on this page open their listings.
What can replace the TDA7850?
Parts like it in the library: the TDA7388 by STMicroelectronics, the TDA7851L by STMicroelectronics, the TCB001HQ(Z) by Toshiba and the STPA003OD-4WX by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the TDA7850?
