The seventh lead is a source Kelvin connection that improves gate-drive loop inductance by separating the power current path from the gate-drive return — important for clean switching at high di/dt. The large exposed tab carries the 375 W power dissipation rating; the board copper area and thermal vias under the tab determine the real junction temperature in the application. No end-of-life notice or successor part is recorded.","metaTitle":"AUIRFS8409-7TRL N-Channel MOSFET, 40V 240A, 0.75 mOhm","metaDescription":"Infineon HEXFET N-channel MOSFET, 40V drain-source, 240A continuous drain, 0.75 mOhm Rds(on) at 100A.
