It comes in a TO-220 through-hole package. The 450V Vds rating puts this part in the high-voltage class — it handles off-line rectified DC bus voltages (up to 400V nominal) with margin for transients. The 8A continuous drain current is the DC limit at 25°C case temperature; derate for higher ambient or poor heatsinking. The 125W power dissipation assumes the case is held at 25°C — in a real enclosure with a modest heatsink, the usable dissipation is lower, so the thermal path from junction to ambient governs the safe operating area. No special reflow profile needed — hand-solder or wave-solder friendly.","metaTitle":"IRF441 N-Channel MOSFET, 450V 8A 125W, TO-220","metaDescription":"IRF441 N-Channel MOSFET from Infineon Technologies, 450V drain-source, 8A continuous drain current, 125W power dissipation.
