These new devices are built using proprietary AlphaMOS technology, designed for efficient switching and dependable reliability. The device structure of these solutions allows for a smooth dv/dt and di/dt transition during hard switching, thereby reducing the ringing typically experienced with other superjunction-type devices. Furthermore, these devices offer 3x the avalanche current capability versus comparable superjunction solutions and enables power circuits to outlast fault conditions such as power line surges and lighting surges. These solutions are available in 4A, 3A, and 2.5A varieties in the DPAK green package and are 100% Rg and UIS tested.

"As builders and homeowners move towards replacing conventional lighting fixtures with LED lighting, there is an ever increasing need for power solutions that are robust and efficient." said Stephen Chang, Sr. Product Marketing Manager at AOS. "Our newest 600VAlphaMOS additions offer excellent avalanche ratings in addition to smooth switching performance to meet these power requirements."
