Alpha and Omega Semiconductor Limited announced the release of a fast switching 600V αMOS5 Super Junction MOSFETs in SMD-type TOLL Package. αMOS5 is AOS’s latest generation of high voltage MOSFET, designed to meet the high efficiency and high-density needs for quick charger, adapter, PC power, server, industrial power, telecom, and Hyperscale datacenter applications.

The new  aMOS5 TOLL product’s footprint is only 115mm², which is 23% smaller than that of D2PAK. Its package thickness is 2.3mm, an almost 50% height reduction versus D2PAK. The reduced package inductance and parasitics of the TOLL package enable power designs to reach the next level of switching efficiency, EMI performance, and ease-of-use. The first Fast Switching aMOS5 TOLL product will be available as AOTL125A60, a 600V device of 125mOhm. Upcoming aMOS5 TOLL products will provide a much wider range of Rds(on), covering applications from 200W to 3kW.

Furthermore, aMOS5 TOLL provides a current capability of up to 100A in a 125mohm device, supporting today’s most demanding Server PFC and PV Inverter applications, which require both high current rating and small form factor. The Automated Optical Inspection (AOI) Capability and Enhanced Solder Contact Area of αMOS5 TOLL also help improve the system and board-level reliability of power supplies that need to serve long life cycles.

Additionally, aMOS5 High Voltage TOLL package features Kelvin Source connection, which significantly improves switching performance by reducing switch-on loss through separate power and drive sources.

As part of the new release, AOTL125A60 (600V 125mOhm TOLL) is immediately available for production quantities.  For 1000pcs, the unit price is $3.3.
