For a rework tech, that means no hot-air profile, no BGA reball — just a soldering iron and a desoldering pump. The metal tab carries the drain potential, so the heatsink interface needs an insulating pad or the chassis must float. At 62 W maximum dissipation, the tab is the primary thermal path; a proper thermal compound and a bolted heatsink keep the junction below 175°C even under sustained load.","metaTitle":"BUK7575-55A,127 N-Channel TrenchMOS MOSFET, 55V 20.3A TO-220","metaDescription":"Nexperia BUK7575-55A,127 N-channel TrenchMOS MOSFET. 55 V drain-source, 75 mOhm Rds(on) at 10 V, 20.3 A continuous drain.
