150 V, 105 A — where this HEXFET sits in the power chain
This part targets 48 V, 72 V, and 80 V bus systems — motor drives, battery protection, DC-DC converters, and power supplies where the voltage margin above a 48 V nominal rail is comfortable without pushing into 200 V class parts.
At 11.8 mOhm max with 63 A drain current and 10 V gate drive, the conduction loss at full load is under 50 W — the bulk of the 380 W dissipation budget goes to switching losses as frequency climbs. The 110 nC total gate charge at 10 V means the driver must source about 1.1 A peak to switch at 100 kHz with reasonable rise times; a standard 2 A gate-driver IC handles it cleanly. Input capacitance of 5320 pF at 50 V drain-source is moderate for this current class — the driver sees a manageable capacitive load.
Temperature range and package — rework and environment
The D2PAK-7 (TO-263-7) surface-mount package has a large exposed drain tab on the bottom — the board copper area under that tab sets the thermal resistance. Reworking a D2PAK takes a hot plate or bottom-side preheater; the tab soaks heat fast, so a top-side hot-air nozzle alone risks lifting the pad on the opposite side. Orientation is unambiguous — the tab is drain, the six leads are gate and source, and the beveled corner marks pin 1.
