A new power MOSFET technology achieves a further milestone in efficiency

This work introduces the characteristics and properties of the latest trench MOSFET technology released to the market. Based on the advantages of a revolutionary new cell design combined with the benefits of an advanced manufacturing technology, this new device family brings together the benefits of exceptionally low conduction losses, superior switching performances, improved SOA and good ruggedness. These features make it the best fit for high switching frequency applications, supporting the trend towards significantly higher efficiency while enabling designs for higher power densities and cost effectiveness. Typical applications for these MOSFETs include telecom, server, datacom as well as solar applications, drones, e-bikes, power tools and many other battery-powered applications (BPA). Results presented in this work focus on the 100 V voltage class intended for use in fast switching DC/DC telecom switch-mode power supplies (SMPS), and compares the new technology with its predecessor generation.
