Infineon BSC350N20NSFD OptiMOS™ 5 Power MOSFET for High-Efficiency Power Conversion

Modern power conversion systems demand semiconductor devices that deliver not only high performance but also exceptional efficiency and reliability. The Infineon BSC350N20NSFD, part of the advanced OptiMOS™ 5 family, stands out as a benchmark for power MOSFET technology, specifically engineered to meet the rigorous requirements of contemporary switched-mode power supplies (SMPS), motor drives, and DC-DC converters.

A key highlight of the BSC350N20NSFD is its ultra-low on-state resistance (RDS(on)) of just 3.5 mΩ maximum. This exceptionally low resistance is critical for minimizing conduction losses, which directly translates into higher system efficiency and reduced heat generation. By operating cooler, systems can achieve greater power density, allowing for smaller form factors and reduced cooling requirements. This makes the device ideal for high-current applications where every milliohm counts.

Furthermore, the MOSFET boasts a 200V drain-source voltage rating, providing a robust safety margin for operations in 48V bus systems, industrial power tools, and telecom infrastructure. The OptiMOS™ 5 technology also features superior switching performance, characterized by low gate charge (Qg) and output capacitance (Coss). These attributes ensure fast switching transitions, which are vital for high-frequency operation. Reduced switching losses allow designers to push switching frequencies higher, leading to the use of smaller passive components like inductors and capacitors, thereby lowering overall system cost and size.

The device is housed in an SuperSO8 package, which offers an excellent power-to-size ratio and improved thermal characteristics. This packaging innovation enhances heat dissipation, enabling the MOSFET to handle high power levels reliably. Additionally, the high body diode robustness ensures reliable operation in hard-switching and freewheeling applications, increasing the longevity and durability of the end product.

From solar inverters and server PSUs to battery management systems, the BSC350N20NSFD provides a versatile and high-performance solution that empowers engineers to push the boundaries of efficiency and power density.
