The IPA80R310CE: That 800 V Vdss puts it squarely in the 400 V bus / PFC / flyback converter class — you get roughly 2× derating margin off a 400 V rail, which is the standard practice for offline SMPS designs. The 310 mOhm Rds(on) is the figure that drives conduction loss at the 16.7 A continuous drain rating (Tc): at 11 A the dissipation in the channel alone is about 37.5 W, which the 35 W package limit (Tc) keeps in check only with a good heatsink on the Full Pack tab.
Gate drive and switching — what the numbers tell you
The gate threshold voltage maxes at 3.9 V at 1 mA drain current, so a standard 10 V gate drive (the recommended drive voltage for minimum Rds(on)) is well above the threshold — no logic-level gate drive required, but it also won't fully enhance at 5 V. Gate charge is 91 nC at 10 V, which is moderate for an 800 V device; expect a gate driver capable of sourcing at least 1 A peak to keep switching transitions crisp and avoid miller plateau dwell. Input capacitance is 2320 pF at 100 V Vds — that number feeds the driver's turn-on energy and the switching loss calculation at frequency.
Package and mounting — TO-220 Full Pack specifics
The TO-220 Full Pack (PG-TO220 Full Pack) is a fully isolated through-hole package — the metal tab is not electrically connected to the drain, which simplifies heatsinking because you don't need an insulating pad. The through-hole leads suit point-to-point wiring or PCB mounting with a 0.1-inch pitch footprint.
The 150 °C TJ max is typical for CoolMOS parts and allows some headroom in a 85 °C ambient with proper heatsinking.
