MOSFETs improve on-state resistance and switching efficiency in automotive applications

Infineon Technologies AG is extending its portfolio of next-generation OptiMOS 7 MOSFETs for automotive applications: the portfolio of 40V products now includes further devices in robust, lead-free packages. In addition, 80V and 100V OptiMOS 7 MOSFETs are now also obtainable. The MOSFETs are optimised for all standard and future automotive 48V applications, including electric power steering, braking systems, power switches in new zone architectures, battery management, e-fuse boxes, DC-DC, and BLDC drives in various 12V and 48V electrical system applications. They are also suitable for other transportation applications such as LEV, e2wheelers, eScooters, eMotorcycles, and commercial and agricultural vehicles (CAV).

"As a technology leader in power semiconductors, Infineon is committed to shape the future technology standards in automotive power MOSFETs in terms of power efficiency, innovative and robust power packaging with high quality," said Axel Hahn, senior vice president and general manager Automotive LV MOSFETs of Infineon. "We are providing our customers a diverse product portfolio and are addressing all their requirements to drive the development of modern automotive applications."

By combining 300mm thin-wafer technology and innovative packaging, the new technology provides significant performance advantages in all available voltage classes. As a result, the components are now obtainable in various rugged automotive power packages, including Single SSO8 (5x6), Dual SSO8 (5x6), mTOLG (8x8) and sTOLL (7x8). The family offers high power density and energy efficiency with the industry's lowest on-state resistance (e.g. 1.3mOhm max in a single SSO8 (5x6) 80V package) in the smallest form factor. The devices also offer reduced switching losses, improved SOA robustness and high avalanche current capability. With this, they allow a highly efficient system design for tomorrow's automotive applications.
