Extra-Rugged, Cool-Running MOSFETs Drive Up Power Density
Alpha and Omega Semiconductor (AOS) rolled out its latest 600-V super junction MOSFETs: the AOGT037V60DE2 and AOGT060V60DE2. Featuring robust top side-cooling, AOS said the MOSFETs have been optimized for use across a wide range of higher-voltage applications, including servers, telecom rectifiers, solar inverters, motor drives, and industrial systems, which are all pursuing higher efficiency and increased power density.
The new devices offer exceptional body-diode ruggedness (di/dt = 1500 A/µs), superior avalanche (UIS) capability, and extended short-circuit withstand time (SCWT). These capabilities are closely aligned with the needs of boost PFC, totem-pole PFC (slow leg), LLC resonant, and other topologies. They also fit into applications like phase-shifted full-bridge (FSFB) converters, cyclo-converters, and switch-mode power supplies (SMPS).
The AOGT037V60DE2 (600 V, 37 mΩ) and AOGT060V60DE2 (600 V, 60 mΩ) come in top-side-cooled GTPAK packages, allowing system designers to optimize thermal dissipation and reclaim PCB space for higher power density.

Lee Goldberg is a self-identified “Recovering Engineer,” Maker/Hacker, Green-Tech Maven, Aviator, Gadfly, and Geek Dad. He spent the first 18 years of his career helping design microprocessors, embedded systems, renewable energy applications, and the occasional interplanetary spacecraft. After trading his ‘scope and soldering iron for a keyboard and a second career as a tech journalist, he’s spent the next two decades at several print and online engineering publications.
Lee’s current focus is power electronics, especially the technologies involved with energy efficiency, energy management, and renewable energy. This dovetails with his coverage of sustainable technologies and various environmental and social issues within the engineering community that he began in 1996. Lee also covers 3D printers, open-source hardware, and other Maker/Hacker technologies.
Lee holds a BSEE in Electrical Engineering from Thomas Edison College, and participated in a colloquium on technology, society, and the environment at Goddard College’s Institute for Social Ecology. His book, “Green Electronics/Green Bottom Line - A Commonsense Guide To Environmentally Responsible Engineering and Management,” was published by Newnes Press.
Lee, his wife Catherine, and his daughter Anwyn currently reside in the outskirts of Princeton N.J., where they masquerade as a typical suburban family.
