Alpha and Omega Semiconductor Limited a power semiconductors and power ICs fabless company, today announced the release of 700V and 600V αMOS5™ Super Junction MOSFET families in SMD-type DFN5x6 and DFN8x8 packages. αMOS5 is AOS’ latest generation of high voltage MOSFET, targeting Quick Charger, Adapter, PC Power, Server, Industrial Power, Telecom, and Hyperscale Datacenter applications.

New αMOS5 DFN8x8 product’s footprint is only 64 mm², which is 57% smaller than that of D2PAK. Its package thickness is 0.9mm, an 80% height reduction versus D2PAK. The much lower source inductance of DFN8x8 package versus D2PAK helps significantly reduce gate ringing and Turn-on loss (Eon).

The first wave of αMOS5 DFN products will be available as one 600V device of 210mOhm in DFN8x8 ( AONV210A60) and two 700V devices of 660mOhm and 1.6Ohm in DFN5x6 respectively ( AONS660A70F and AONS1R6A70). The future DFN product families will provide a much broader range of Rds(on).

Pricing and Availability

As part of the first wave release, AONV210A60 (600V 210mOhm DFN8x8), AONS660A70F (700V 660mOhm DFN5x6) and AONS1R6A70 (700V 1.6Ohm DFN5x6) are immediately available for production quantities. For 1000pcs, the unit prices are $2.7 for AONV210A60, $1.05 for AONS660A70F and $0.72 for AONS1R6A70.
