Vishay SOT-227 modules boost conversion efficiency
Vishay Intertechnology has introduced four new power modules featuring 650 V superjunction MOSFETs in the industry-standard SOT-227 package.
Designed to deliver an optimised balance between conduction and switching losses, the VS-FC50SA65, VS-FC100SA65, VS-FC150SA65, and VS-FC50LA65 support high efficiency power conversion in industrial applications.
The power modules include three devices in a single-switch configuration with nominal current ratings of 50 A, 100 A, and 150 A, as well as a 50 A device in a low side chopper configuration that integrates a 650 V SiC diode. All four components leverage the latest high efficiency 650 V superjunction MOSFET technology to achieve a highly competitive tradeoff between on-resistance and gate charge. This allows designers to reduce power losses while maintaining fast switching performance.
The VS-FC50SA65, VS-FC100SA65, VS-FC150SA65, and VS-FC50LA65 will be used as DC/DC converters and DC/AC inverters in solar power inverters and hydrogen generation and fuel cell systems; auxiliary electronics and energy transportation within HVDC infrastructure; charging stations; switch mode power supplies and welding and cutting equipment; UPS, lighting systems, and rail power supplies; and medical imaging equipment such as X-ray and MRI systems.
The power modules offer a wide temperature range of -55 °C to +150 °C. For existing designs, the devices’ SOT-227 package provides a drop-in replacement for competing solutions, lowering costs by eliminating the need for PCB redesigns.
