250 V N-channel in a compact TDSON-8 — what the ratings mean for the BOM
The Infineon BSC600N25NS3GATMA1 is a 250 V N-channel MOSFET from the OptiMOS series, rated for 25 A continuous drain current at 25 °C case temperature. The 60 mOhm maximum on-resistance at 10 V gate drive defines the conduction loss at full load. The part is housed in a PG-TDSON-8-1 package — an 8-lead PowerTDFN with an exposed pad for thermal dissipation. The surface-mount footprint is standard for this class, but the pad layout and solder-paste stencil aperture must match the manufacturer's land pattern to achieve the rated thermal resistance. The junction temperature range spans -55°C to 150°C, covering military and automotive thermal extremes.
