AOS introduces new 600V Super Junction MOSFETs
Power chip company Alpha and Omega Semiconductor (AOS) has released αMOS E2 600V Super Junction MOSFETs, engineered to meet the growing demands for enhanced efficiency and increased power density management capabilities.
These top-side-cooled 600V Super Junction MOSFETs are designed to suit a wide range of today’s higher voltage applications, including servers, workstations, telecom rectifiers, solar inverters, motor drives and industrial power systems. These also meet the critical requirements in multiple topologies such as boost PFC, totem-pole PFC (slow leg), LLC resonant, PSFB and cyclo-converters.
AOS’ αMOS E2 High‑Voltage Super Junction MOSFET platform is said to feature high body-diode ruggedness (di/dt = 1500 A/µs), superior avalanche (UIS) capability, and short-circuit withstand time (SCWT). Furthermore, AOS combines this αMOS E2 silicon with its top-side-cooled GTPAK package to maximise thermal performance via the top-side cooling pad. As a result, system designers can fully optimise thermal dissipation and reclaim PCB space to maximise overall power density. By co-optimising both the electrical and thermal paths, system performance and long-term reliability are greatly enhanced.
“Our top-side cooled GTPAK products, such as the AOGT037V60DE2 and AOGT060V60DE2, are engineered to meet the demands of high-performance AC/DC power supplies, DC/DC converters and DC/AC solar inverters. Electromagnetic emission (EMI) and density bottlenecks of traditional bottom-side cooling have been a major engineering hurdle. Our αMOS E2 top-side cooled solutions give designers a premier solution for mid-to-high-power systems, empowering the performance-driven power infrastructure, power supply units, and renewable energy systems,” said Simon Yu, senior manager of HV Product Line at AOS.
The AOGT037V60DE2 (600 V, 37 mΩ) and AOGT060V60DE2 (600 V, 60 mΩ) in top-side-cooled GTPAK packages are now available in production quantities with a lead time of 16 weeks. The unit prices for 1,000-piece quantities are $6.00 and $3.00, respectively.
