αMOS5 is AOS’ latest generation of high voltage MOSFET, designed to meet the high efficiency and high-density needs for Quick Charger, Adapter, PC Power, Server, Industrial Power, Telecom, and Hyperscale Datacenter applications.

The families are designed to fit into a variety of hard and soft switching topologies including PFC, Flyback, LLC, ZVS FB, and other resonant structures. With 30% higher figure of merit compared the previous generation, αMOS5 helps further reduce the conduction and switching losses and improves SMPS design efficiency.

The 700V and 600V αMOS5 Super Junction MOSFET families will be manufactured in AOS’ 300mm fab to ensure AOS’ competence in technology, quality, and capacity to serve worldwide OEM and ODM customers. Both families provide a broad selection of RDS(ON) and package options to address applications of different power ratings and design form factors. The lead 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,” said Richard Zhang, Director, High Voltage MOSFET Product Line at AOS. “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 RDS(ON), BVdss, and package provide complete solutions for both low power and high power SMPS designs.”

As part of the first wave release, the AOTF190A60CL (600V 190mOhm), AOTF380A60CL (600V 380mOhm) and AOD600A70R(700V 600mOhm) are immediately available for mass production. For 1000pcs, the unit prices are $1.485 for AOTF190A60CL, $1.0950 for AOTF380A60CL and $0.72 for AOD600A70R.
