Overview
The IRFR420 is a MOSFET made by Texas Instruments in a DPAK package with 3 pins. -55℃~+150℃ 1 N-channel 19nC@10V 2.5A 350pF 3Ω@10V 4V 500V 50W 9.6pF N-Channel DPAK MOSFETs.
PCBKit's library has its KiCad symbol (Transistors:N-MOSFET-D 1G 2S 3D, from CERN's library) and its footprint (ICs And Semiconductors SMD:TO228P991X239-3N-R552X520, from CERN's library), ready for a KiCad board. JLCPCB lists it (part C3288391).

Questions
Is there a KiCad symbol and footprint for the IRFR420?
Yes. The symbol is Transistors:N-MOSFET-D 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 IRFR420?
DPAK, with 3 pins. Its footprint is drawn on this page.
Where is the IRFR420 datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the IRFR420?
JLCPCB lists it as part C3288391, with 0 in stock; the sellers' links on this page open their listings.
What can replace the IRFR420?
Parts like it in the library: the FDD5614P by TECH PUBLIC, the IPD320N20N3G by Infineon Technologies, the STD20NF20 by STMicroelectronics and the FDD13AN06A0-F085 by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
