Alpha and Omega Semiconductor expands DFN2x2 portfolio with new 40V and 60V MOSFETs

SUNNYVALE, USA: Alpha and Omega Semiconductor Ltd (AOS), a designer, developer and global supplier of a broad range of power semiconductors, released the AON2240 and AON2260, the newest additions to its new 40V and 60V AlphaMOS medium voltage portfolios.

These new products are packaged in the small, ultra-thin (0.6mm) DFN 2mm x 2mm package and are well suited for a wide range of applications that include secondary side synchronous rectification in DC/DC and AC/DC converters, POL modules for telecom systems, POE networking applications, and small motors.

The 40V AON2240 and 60V AON2260 are based on AOS' proprietary AlphaMOS technology that offers the combination of very low RDS(ON) and fast switching characteristics. With the green DFN2x2 package, circuit designers now have more options in delivering power to space constrained applications. These devices are 100 percent Rg and UIS tested.

"Circuit designers are constantly optimizing space, performance and cost," said Stephen Chang, senior product marketing manager at AOS. "AON2240 and AON2260 provide the flexibility of the small DFN2x2 package. At the same time, these devices also deliver the benefits of low on-resistance and output capacitance to minimize power losses associated with conduction and switching."

AON2240 technical highlights
* 40V N-channel MOSFET in the DFN2x2 package.
* RDS(ON) < 21 mOhms at VGS = 10 V.
* RDS(ON) < 29 mOhms at VGS = 4.5 V.
* COSS = 112 pF (typ).
* Qg (4.5 V) = 3 nC (typ).

AON2260 technical highlights
* 60V N-channel MOSFET in the DFN2x2 package.
