Power MOSFETs for Portable Applications

Alpha and Omega Semiconductor Limited announced power MOSFETs in an ultra-thin (0.8 mm) DFN 3x3 package. These devices are implemented on AOS' proprietary AlphaMOS technology. The combined benefits of longer battery life and a compact form factor make these devices ideal for space-constrained portable applications such as tablet PCs, smart phones, eReaders, notebook computers, digital cameras and portable music players.

The AON7421 and AON7423 are best-in-class 20V P-channel devices with the lowest RDS(ON) in the market of similar package types. AON7421's on-resistance value at a 2.5V gate voltage is 20% less than the closest competitive device. AON7423 is a low threshold device that operates with a gate drive as low as 1.5V, allowing efficient load switching for low voltage supply rails.

All three devices are halogen-free and 100% UIS and Rg tested.

These devices are immediately available in production quantities with a lead-time of 12 weeks. The unit price for 1,000 pieces is $0.70 for each device.
