800 V CoolMOS — where this Rds(on) tier fits
The IPW80R280P7XKSA1: It belongs to the CoolMOS P7 series, a high-voltage superjunction family for hard-switching topologies. The 36 nC total gate charge at 10 V keeps drive current manageable.
Gate drive and switching — the 10 V requirement
The IPW80R280P7XKSA1 specifies Rds(on) at a 10 V gate drive, with a maximum gate threshold of 3.5 V at 360 µA. Input capacitance is 1200 pF at 500 V Vds — moderate for an 800 V device. Combined with 36 nC gate charge, the switching energy per transition stays low enough that a heatsink sized for 101 W maximum dissipation at case temperature will handle 100+ kHz operation in a typical PFC stage.
Package and thermal — TO-247-3 mounting
The PG-TO247-3-41 package is the standard three-lead through-hole TO-247 with a large backside drain tab. The 101 W power dissipation rating at case temperature assumes the tab is bolted to a heatsink with thermal interface material.
