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.
Active lifecycle — no LTB risk
The BSC0402NSATMA1 carries an Active product status from Infineon, with ROHS3 compliance. No last-time-buy or phase-out notice is in effect. For a BOM line that needs a 150V logic-level N-channel, this part is a current-production choice — not a surplus scavenge.
