The headline number is the 2.3 mOhm maximum on-resistance at Vgs = 10 V and 75 A — that is about the resistance of a few centimetres of heavy-gauge wire. In a high-current switching circuit like a DC motor drive or a battery disconnect, that low Rds(on) keeps conduction losses low enough that the TO-220AB package can handle 300 W dissipation with adequate heatsinking. ## Gate charge and driver sizing Gate charge is 240 nC max at Vgs = 10 V. That is a substantial charge — the gate driver must source and sink that charge each switching cycle. At 100 kHz, the average gate drive current is 24 mA; at 200 kHz it doubles to 48 mA. A standard logic-level gate driver will struggle; plan on a dedicated driver with at least 2 A peak output to keep switching edges clean and avoid Miller-turn-on issues. ## Temperature range and field deployment That is military-grade thermal headroom — the part can sit in an engine bay, a downhole tool, or an outdoor telecom rectifier without derating at the hot end. The 175 °C limit also means the thermal interface to the heatsink must be managed: the 300 W dissipation rating assumes the case is held at 25 °C, so in practice the real power limit is set by the heatsink and airflow. ## Sourcing and lifecycle posture ROHS3 compliant. The part is a through-hole TO-220AB, which means it is field-replaceable with basic tools: a soldering iron and a desoldering pump are enough to swap it on site.","metaTitle":"IRF2804PBF HEXFET N-Channel MOSFET, 40V 75A TO-220AB","metaDescription":"IRF2804PBF N-channel MOSFET from Infineon HEXFET series. 40V Vdss, 75A continuous drain, 2.3 mOhm Rds(on) at 10V.
