No mica washer or thermal compound pad needed between the tab and the heatsink — the isolation is built into the moulded body. That saves assembly time and eliminates one failure point in high-vibration environments like pumps or industrial fans. The 54 W maximum power dissipation at case temperature assumes a decent heatsink; the junction can run up to 175°C. Gate charge is 94 nC at 10 V, and input capacitance is 1400 pF at 25 V drain. For a 100 kHz hard-switched converter you need a gate driver that can source and sink that charge fast enough to keep switching losses in check — figure a driver with at least 2 A peak output.","metaTitle":"IRFI540NPBF N-Channel MOSFET, 100 V, 20 A, 52 mOhm","metaDescription":"IRFI540NPBF N-Channel MOSFET from Infineon HEXFET series. 100 Vdss, 20 A continuous drain, 52 mOhm Rds(on) at 10 V.
