The part comes in a TO-220-3 Full Pack package (PG-TO220-FP), which provides full isolation between the mounting tab and the die. ## On-resistance and gate charge — the switching loss trade-off This is the figure to use for worst-case conduction loss calculations at the target operating current. Total gate charge at 10 V is 23 nC, which keeps the drive current requirement modest — a typical gate-driver IC can switch this MOSFET at frequencies up to 100 kHz without excessive dissipation in the driver. Input capacitance is 570 pF at 100 V drain-source. The 800 V rating and 3.9 A current capability suit this device for offline flyback converters, auxiliary power supplies, and PFC stages. ## Full-pack isolation and thermal path The PG-TO220-FP package has the die mounted on an isolated leadframe, so the metal tab is electrically floating. Maximum power dissipation is 31 W at case temperature, derated to zero at 150°C junction. Through-hole mounting with a single M3 screw to a heatsink is the standard assembly method. The full-pack construction means the heatsink does not need to be grounded, which can simplify layout in non-isolated topologies.","metaTitle":"Infineon IPA80R1K4CEXKSA2 CoolMOS N-Ch MOSFET, 800 V, 3.9 A","metaDescription":"Infineon IPA80R1K4CEXKSA2 CoolMOS N-channel MOSFET, 800 Vdss, 3.9 A, 1.4 Ohm Rds(on), TO-220 Full Pack.
