The SPA04N50C3XKSA1: N-channel MOSFET, 560 V drain-source, 4.5 A continuous drain, 950 mOhm Rds(on) at 10 V gate drive, TO-220 Full Pack.
TO-220 Full Pack — isolated tab, no pad needed
This part comes in a TO-220-3 Full Pack (PG-TO220-3-31) — the plastic body encloses the back of the die so the mounting tab is electrically isolated. Through-hole mounting suits point-of-load boards where the FET gets bolted to a chassis or heatsink.
