Source down packaging achieves low resistance and inductance

Flip chip expertise by Alpha and Omega Semiconductor has culminated in Source Down capability and packaging technology that offers a low resistance and inductance. The company has introduced Source Down in a DFN 5.0 x 6.0mm package with AlphaSGT shield gate technology.

The 40V AOE66410 is intended for telecommunications applications for secondary rectification (SR), in half bridge configuration for brushless DC motor applications, and battery management where paralleling is important, advises Alpha and Omega.

The AOE66410 has the same form factor of a standard DFN 5.0 x 6.0mm package but the source pad has the largest connection to the PCB. This will enable power supply designers to parallel devices more easily and have a larger thermal area to dissipate any losses, explains Alpha and Omega. The AOE66410 has a one mOhms max at 10Vgs with a maximum drain current of 100A at 25 degrees C case temperature.

“Source Down can offer a significant improvement in PCB layout and simplify new parallel designs, which are suited for high-power telecommunication power supplies,” said Peter H. Wilson, marketing director of the MOSFET product line at AOS.

The AOE66410 is immediately available in production quantities with a lead time of 12 to 14 weeks.

Alpha and Omega Semiconductor is a designer, developer and supplier of a broad range of power semiconductors, including MOSFETs, IGBTs, IPMs, TVS, HVICs, GaN/SiC, power IC and digital power products. AOS has developed intellectual property (IP) and technical knowledge to introduce innovative products to address the increasingly complex power requirements of advanced electronics. AOS differentiates itself by integrating its discrete and IC semiconductor process technology, product design, and packaging expertise to develop high performance power management solutions.
