The power dissipation of 40W is only achievable with an infinite heatsink. In free air, derate by 0.5 W/°C above 25°C ambient.
Manufacturers often include reference designs in the . Here are the three most common topologies:
In a typical application, the source connects directly to the positive supply rail (e.g., +5V or +12V). Pulling the gate to ground (0V) creates a negative ( V_GS ) (e.g., -5V), switching the load connected to the drain.
Designers must pay attention to the parameter in the datasheet.
, to drive the precision motors that control print head movement and paper feeding. Core Specifications
