Super junction MOSFETs suit hard and soft switching topologies

Alpha and Omega Semiconductor has released 700 and 600V αMOS5 super junction MOSFETs produced at its 300mm fab.

The 700 and 600V αMOS5 super junction MOSFET families are optimised for efficiency, ruggedness and ease-of-use in both hard and soft switching topologies, says AOS.

The αMOS5 is the company’s 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, telecomms and hyperscale data centre applications.

The super junction MOSFETs are designed to fit into a variety of hard and soft switching topologies including PFC, Flyback, LLC, ZVS FB and other resonant structures. They have 30 per cent lower RDS x A compared with the previous generation, says AOS, enabling the αMOS5 MOSFETs to further reduce the conduction and switching losses and increase the efficiency of switch mode power supplies.

The 700 and 600V αMOS5 super junction MOSFET families will be manufactured in AOS’ 300mm fab. Both families provide a broad selection of RDS(ON) and package options to address applications of different power ratings and design form factors, including the best-in-class 600V 40mOhm device in a TO-247 package, says 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, said Richard Zhang, director of the high voltage MOSFET product line at AOS.

The company has announced that the AOTF190A60CL (600V 190mOhm), AOTF380A60CL (600V 380mOhm) and AOD600A70R (700V 600mOhm) are immediately available for mass production.

Alpha and Omega Semiconductor (AOS) designs, develops and supplies a broad range of power semiconductors, including a wide portfolio of  power MOSFET, IGBT, IPM, TVS, HVIC, GaN/SiC, power IC and digital power products.

AOS has developed extensive intellectual property and technical knowledge and differentiates itself by integrating its discrete and IC semiconductor process technology, product design, and advanced packaging expertise to develop high performance power management solutions. AOS’ portfolio of products targets high-volume applications, including portable computers, flat panel TVs, LED lighting, smart phones, battery packs, consumer and industrial motor controls and power supplies for TVs, computers, servers and telecommunications equipment.
