This is a normal level 120 V MOSFET in SuperSO8 packaging with 3.04 mOhm on-resistance. ISC030N12NM6 is part of Infineon’s OptiMOS™ 6 power MOSFET family.
The OptiMOS™ 6 power MOSFET 40V family is optimized for a variety of applications and circuits, such as synchronous rectification in switched mode power supplies (SMPS) in servers, desktop PCs, wireless chargers, quick chargers and ORing circuits. Improvements in on-state resistance (RDS(on)) and figure of merits (FOM - RDS(on) x Qg and Qgd) enable designers to increase efficiency, allowing easier thermal design and less paralleling, leading to system cost reduction.
