The junction temperature range spans -55°C to 175°C, which covers automotive under-hood and industrial ambient extremes — the 175°C ceiling gives headroom for derating the 140 W power dissipation at elevated case temperatures.","metaTitle":"AUIRF4104STRL N-Channel MOSFET, 40V 75A D2PAK","metaDescription":"AUIRF4104STRL HEXFET N-channel MOSFET, 40V, 75A, 5.5mOhm Rds(on), D2PAK.
