Alpha and Omega Semiconductor offers significant reductions in RDS(ON) for MOSFETs in DFN3.3x3.3 package

SUNNYVALE, USA: Alpha and Omega Semiconductor (AOS) has released two new power MOSFETs that combine the latest advances in silicon process and high density packaging technologies.

The AON7428 and AON7405 enable design engineers to achieve very high current density load switching solutions in space constrained applications including battery packs, notebook computers and redundant power supplies.

The AON7428 is a 2.3mΩ N-channel, and the AON7405 is a 5.1mΩ P-channel MOSFET. Developed with AOS’s G4 30V Trench technology, and combined with a Power DFN3.3x3.3 package, these devices offer among the lowest RDS(ON) in their class.

“We are pushing the boundaries of miniaturization with these new Power MOSFETs,” said David Grey, Director of Product Marketing at AOS. “This level of performance is usually associated with packages three times this size and gives designers more options when PCB space is limited.”

Both devices are housed in the DFN3.3x3.3 package and are available immediately in production quantities. The unit price of 1,000 pieces is as follows: AON7428 at $0.85, and AON7405 at $0.88.
