Vishay Intertechnology SOT-227 Power Modules Increase Power Conversion Efficiency
Vishay Intertechnology, Inc. has introduced a new series of power modules featuring 650 V superjunction MOSFETs in the industry-standard SOT-227 package. These Vishay Semiconductors modules, including part numbers VS-FC50SA65, VS-FC100SA65, VS-FC150SA65, and VS-FC50LA65, are engineered to improve power-conversion efficiency across various industrial applications.
The core innovation lies in their optimised balance between conduction and switching losses, achieved through the latest high efficiency 650 V superjunction MOSFET technology. This design approach allows for a competitive trade-off between on-resistance and gate charge, enabling designers to minimise power losses while sustaining rapid switching performance.
A significant differentiator for these power modules is their SOT-227 package, which serves as a drop-in replacement for existing solutions. This compatibility eliminates the need for costly and time-consuming PCB redesigns, offering a direct path to upgrading system efficiency. Furthermore, the modules are built to withstand challenging environments, operating reliably across a wide temperature range of -55 °C to +150 °C.
The product line includes three single-switch configurations with nominal current ratings of 50 A, 100 A, and 150 A, alongside a 50 A low-side chopper configuration that integrates a 650 V SiC diode. This versatility positions the Vishay SOT-227 power modules as a robust solution for a broad spectrum of high-efficiency power conversion needs.
