The 150 W power dissipation rating assumes the case temperature is held at 25°C — in a real system with a heatsink and forced air, the derating curve from the datasheet governs the safe operating area at elevated ambient temperatures.","metaTitle":"IRFAF50 Infineon N-Channel MOSFET, 1.85Ω @ 6.2A, 150W","metaDescription":"IRFAF50 N-channel HEXFET MOSFET, 900V, 6.2A switching, 1.85Ω Rds(on).
