Is there a KiCad symbol and footprint for the IRLS540A?
Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2D_3S and the footprint Package_TO_SOT_THT:TO-220F-3_Vertical, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the IRLS540A?
TO-220F-3, with 3 pins. Its footprint is drawn on this page.
Where is the IRLS540A datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the IRLS540A?
JLCPCB lists it as part C3290556, with 0 in stock; the sellers' links on this page open their listings.
What can replace the IRLS540A?
Parts like it in the library: the SVF20N50F by Hangzhou Silan Microelectronics, the SVS20N60FJD2 by Hangzhou Silan Microelectronics, the JCS20N65FH-220MF by Jilin Sino-Microelectronics and the 2SK3148-VB by VBsemi Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
