150V N-channel logic-level switch
The Infineon BSC0402NSATMA1 is a 150V N-channel MOSFET described as logic level. Rated for continuous operation at 150V drain-source, this part suits 48V bus systems, 72V battery stacks, and primary-side switching in flyback or forward converters with up to 100V reflected voltage margins. The logic-level threshold eliminates the level-shift resistor network or driver buffer that a standard-threshold MOSFET would require, saving two to three passives per switch node on a dense PCB.
