This is not a logic-level MOSFET — a 3.3 V gate signal will not fully enhance the channel. The input capacitance is 4574 pF at 25 V drain-source, which together with the 138 nC gate charge means the gate driver must supply several amperes of peak current for fast switching edges in a 100 kHz+ converter.","metaTitle":"IRFH7440TRPBF N-Channel MOSFET, 40 V, 85 A, 2.4 mOhm","metaDescription":"IRFH7440TRPBF N-channel MOSFET, 40 V, 85 A, 2.4 mOhm Rds(on) at 10 V.
