Questions
Is there a KiCad symbol and footprint for the SP40N12P8?
Yes. the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SP40N12P8?
SOP-8L, with 8 pins. Its footprint is drawn on this page.
Where is the SP40N12P8 datasheet?
Siliup publishes it: the Datasheet link on this page opens it.
Where can I order the SP40N12P8?
JLCPCB lists it as part C41355053, with 2,062 in stock; the sellers' links on this page open their listings.
What can replace the SP40N12P8?
Parts like it in the library: the AO4485 by Alpha & Omega Semiconductor, the AO4264E by Alpha & Omega Semiconductor, the CSD88537ND by Texas Instruments and the AO4480 by Alpha & Omega Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
