Infineon BSC118N10NSG: A High-Performance OptiMOS™ Power MOSFET for Advanced Switching Applications

The relentless pursuit of higher efficiency, power density, and reliability in modern electronics drives the continuous innovation in power semiconductor technology. At the forefront of this evolution is Infineon's BSC118N10NSG, a benchmark N-channel power MOSFET that exemplifies the superior performance of the company's proprietary OptiMOS™ technology. Engineered for demanding switching applications, this component is a cornerstone in power conversion systems where every fraction of a watt saved translates into significant performance gains.

Built on a Foundation of Advanced OptiMOS™ Technology

The core strength of the BSC118N10NSG lies in its utilization of Infineon's state-of-the-art OptiMOS™ process. This technology is renowned for achieving an exceptional balance between low on-state resistance (RDS(on)) and outstanding switching performance. The device boasts a maximum RDS(on) of just 11.8 mΩ at 10 V gate-source voltage, which is remarkably low for its voltage class. This ultra-low resistance minimizes conduction losses, allowing for higher efficiency operation, especially in high-current scenarios. The low gate charge (Qg) and small reverse recovery charge (Qrr) further contribute to its prowess by drastically reducing switching losses, enabling systems to operate at higher frequencies without a punitive efficiency penalty.

Key Specifications and Performance Highlights

Housed in a space-saving, thermally efficient SuperSO8 package, the BSC118N10NSG is characterized by a 100V drain-source voltage (VDS) rating and a continuous drain current (ID) of 44 A at 25°C. This robust voltage and current handling capability makes it an ideal candidate for a wide array of applications. Its high-performance metrics are crucial for:

Synchronous rectification in switched-mode power supplies (SMPS) and DC-DC converters.

Motor control and driving circuits in industrial automation and consumer appliances.

High-frequency inverters and power stages in renewable energy systems.

The SuperSO8 package offers a significantly reduced footprint compared to standard D2PAK packages while providing superior thermal conductivity. This allows designers to achieve higher power density in their end products, a critical requirement for compact, modern electronic devices.

Designed for Reliability and System Robustness

Beyond raw performance, the BSC118N10NSG is designed with system integrity in mind. It features a high avalanche ruggedness and an extended safe operating area (SOA), ensuring reliable operation under stressful conditions, including voltage spikes and overloads. Its high maximum junction temperature rating further enhances its reliability in demanding environments.
