Package and mounting — PG-TSDSON-8
The BSC882N03MSG comes in a PG-TSDSON-8 package — Infineon's SuperSO8, a 5x6 mm² footprint with an exposed drain pad. That pad is the primary thermal path; the 69 W power dissipation at case temperature assumes a good solder joint to a copper plane. The surface-mount assembly is standard reflow, but the large pad demands a stencil aperture sized for adequate solder volume — too little and the thermal resistance climbs, too much and you risk bridging the drain to the source pins. The 8-PowerTDFN package code is the JEDEC-equivalent descriptor; the supplier device code PG-TSDSON-8 is what Infineon prints on the reel label.
Thermal and electrical limits for the BOM
Operating junction temperature spans -55 °C to 150 °C. The 2.5 W dissipation at ambient is the bare-board limit; the 69 W at case temperature is what you get with a proper heatsink or PCB thermal vias.
