The IPD200N15N3GATMA1: With 150 V drain-source rating, this MOSFET provides comfortable headroom for 48 V bus systems (telecom, industrial) and 12 V automotive loads where transients can exceed 40 V. The 20 mOhm Rds(on) at 10 V drive means the part is optimised for 10 V gate logic; the 8 V minimum drive voltage allows operation from an 8 V rail with slightly higher on-resistance. At 50 A, the conduction loss is 50 W at 20 mOhm, which the 150 W package rating can handle with proper heatsinking — but in practice, most designs will run well below that continuous current or use pulse operation.
TO-252-3 DPak — footprint and thermal reality
The PG-TO252-3 (DPak) surface-mount package has a large exposed drain tab for solder-down to the PCB copper plane. The 150 W power dissipation rating assumes the tab is soldered to a substantial copper area on a multi-layer board.
