The industry’s first 1700-V SiC MOSFET in an optimized surface-mount package is designed for commercial use in auxiliary power supplies in high voltage power inverter systems. The blocking voltage enables design engineers to replace lower rated silicon MOSFETs with the new SiC MOSFETs, delivering higher efficiency, simplified driver circuitry, and lower thermal dissipation, and resulting in lower total system costs. The SMD package has a 9.075 x 10.130-mm footprint. It includes a separate driver source connection, which reduces gate ringing and provides clean gate signals.
Application of the 1700V SiC MOSFET is anticipated for use in auxiliary power supplies within high power inverters such as solar power inverters, motor drives, UPS equipment, wind-energy converters, and traction power systems. These devices typically buck down dc voltages to operate system logic, protection circuitry, displays, network interface, and cooling fans. They can also be used in the power supplies of three-phase e-meters, or in any converter application that requires high blocking voltages and low capacitance. By enabling the design of single-switch flyback topologies from input voltages spanning 200 to 1,000-V, the SiC MOSFET simplifies the complex drive and snubber circuit elements required for silicon devices. It is fully qualified and available for immediate sampling. Visit wolfspeed.com/power/products for more information.
