The D2PAK (TO-263) footprint with a large copper pad on the PCB is required to pull the 158 W power dissipation away from the die — a two-layer board with limited copper will throttle the current rating.","metaTitle":"Infineon IPB120N04S402ATMA1 N-Channel MOSFET, 40V 120A D2PAK","metaDescription":"Infineon IPB120N04S402ATMA1 OptiMOS N-channel MOSFET, 40V Vdss, 120A Id, 1.8mOhm Rds(on).
