Is there a KiCad symbol and footprint for the STD20NF20?
Yes. The symbol is Transistors:N-MOSFET-DZ 1G 2S 3D and the footprint ICs And Semiconductors SMD:TO228P991X239-3N-R552X520, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the STD20NF20?
TO-252(DPAK), with 3 pins. Its footprint is drawn on this page.
Where is the STD20NF20 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the STD20NF20?
JLCPCB lists it as part C221449, with 1 in stock; the sellers' links on this page open their listings.
What can replace the STD20NF20?
Parts like it in the library: the IPD320N20N3G by Infineon Technologies and the IRFR420 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
