The Infineon IRFS3207ZTRRPBF is a 75 V, 120 A N-channel HEXFET MOSFET in a D²Pak (TO-263) surface-mount package. It is designed for high-current switching in motor drives, DC-DC converters, battery management, and automotive power distribution where low conduction loss and a wide temperature range are required.
Rds(on) is 4.1 mOhm at 75 A, 10 V. The 300 W power dissipation rating is specified at Tc. Gate charge is 170 nC at 10 V. Input capacitance is 6920 pF at 50 V.
Package and thermal path
The 300 W power dissipation rating assumes the tab is connected to a thermal plane; without it, the junction temperature will rise quickly under continuous high current.
