The IAUS300N08S5N014T is a 1.4 mΩ, topside-cooled 80 V MOSFET coming in the TOLT package with Infineon’s leading OptiMOS™-5 technology. Next to others the device is designed for 48V applications. Alongside the 48V auxiliary applications, the device is primarily used in the the DC-DC converter and the main battery switch.
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.
