Vishay has introduced the SOT-227 power module, which enhances power conversion efficiency without requiring changes to the PCB layout
2026-10-19

The device has two configurations: single switch and low side chopper, using advanced 650 V super junction MOSFET technology to optimize the balance between RDS (on) and Qg

Recently, Vishay Intertechnology, Inc. (NYSE stock code: VSH) announced the launch of four new power modules with built-in 650 V super junction MOSFET chips and industry standard SOT-227 packaging - VS-FC50SA65, VS-FC100SA65, VS-FC150SA65, and VS-FC50LA65. Vishay Semiconductors VS-FC50SA65, VS-FC100SA65, VS-FC150SA65, and VS-FC50LA65 achieve excellent balance between conduction and switching losses, supporting efficient power conversion in industrial applications.

The recently released power module includes three single switch configuration devices with nominal rated currents of 50A, 100A, and 150A respectively; another 50A device adopts a low side chopper configuration and integrates 650 V SiC diodes. All four devices adopt advanced and efficient 650V super junction MOSFET technology, which has significant advantages in on resistance and gate charge balance. Designers can reduce power consumption while maintaining fast switching characteristics.

VS-FC50SA65, VS-FC100SA65, VS-FC150SA65, and VS-FC50LA65 can be used as DC/DC converters and DC/AC inverters, suitable for medical imaging equipment such as solar inverters, hydrogen production and fuel cell systems, HVDC infrastructure auxiliary electronic equipment and transmission systems, charging stations, switching power supplies, welding and cutting equipment, uninterruptible power supplies (UPS), lighting systems, rail transit power supplies, X-ray and magnetic resonance (MRI) systems, etc.

Under the harsh environment of the above application, the working temperature range of the power module is -55 ° C to+150 ° C. The device is packaged in SOT-227, providing a plug and play solution for directly replacing competitors in existing designs without changing the PCB layout, thereby saving costs.
