The maximum gate-source voltage is ±20 V, and the threshold voltage is 4 V at 140 µA drain current, so a 10 V gate drive is the recommended bias for minimum Rds(on) operation.","metaTitle":"Infineon IPI120N04S401AKSA1 N-Channel MOSFET, 40 V, 120 A","metaDescription":"Infineon IPI120N04S401AKSA1 OptiMOS N-channel MOSFET, 40 V Vdss, 120 A Id, 1.9 mOhm Rds(on) at 10 V.
