Alpha and Omega Semiconductor is aiming at servers with a pair of 600V super-junction mosfets in 8 x 8 x 0.9mm DFN8x8 packaging, with a Kelvin source. AONV110A60 has 110mΩ on-resistance, and AONV140A60 has 140mΩ. “Years ago, we could hardly imagine high voltage DFN8x8 devices widely adopted for server systems above 400W. People used packages such as TO-220(F) ...
