The new αMOS5 family is designed to fit into a variety of hard and soft switching topologies including PFC, Flyback, LLC, ZVS FB, and other resonant structures. With 30% lower ‟R_DS x A” versus the previous generation, αMOS5 helps further reduce the conduction and switching losses, and drives SMPS design’s efficiency to the next level.

The new 700V and 600V αMOS5 Super Junction MOSFET families will be manufactured in AOS’ world-class 300mm Fab to ensure AOS’ competence in technology, quality, and capacity to serve worldwide OEM and ODM customers. Both 700V and 600V αMOS5 Super Junction MOSFET families provide a broad selection of R_DS(ON) and package options to address applications of different power ratings and design form factors. Our Best-In-Class part is a 600V 40mOhm device in a TO-247 package.

“AOS’ 10 years of High Voltage MOSFET development experience, proprietary silicon know-how, and our 300mm process technologies give us the competitive advantage to bring the most well-balanced and reliable Super Junction MOSFET to the market. Our ‘Tunable Switching Technology’ allows a wide range of dV/dt and makes it possible to achieve the best efficiency in fast switching applications, as well as addressing EMI and Avalanche/UIS challenges without compromising efficiency. The vast choices of AOS High Voltage MOSFET portfolios in R_DS(ON), BVdss, and package provide complete solutions for both low power and high power SMPS designs,” said Richard Zhang, Director, High Voltage MOSFET Product Line at AOS.
