By combining advanced thin-wafer technology with innovative packaging solutions, these components provide significant performance benefits, making them ideal for use in the next generation of automotive power systems.
Infineon Technologies AG has expanded its OptiMOS 7 MOSFET portfolio, enhancing its offerings for automotive applications. The 40 V range now includes lead-free packages alongside new 80 V and 100 V MOSFETs. These additions cater to standard and future 48 V automotive systems, supporting electric power steering, braking systems, power switches in new zone architectures, battery management, e-fuse boxes, DC/DC converters, and BLDC drives for 12 V and 48 V electrical systems.
These MOSFETs are ideal for various transportation applications, including light electric vehicles (LEV), e2wheelers, eScooters, eMotorcycles, and commercial and agricultural vehicles (CAV). The expanded portfolio demonstrates Infineon’s commitment to advancing automotive technology, providing efficient and reliable solutions for modern and future mobility needs.
The key features are:
- High power density and energy efficiency
- Low on-state resistance (e.g., 1.3 mΩ max in a single SSO8 (5×6) 80V package)
- Compact form factor
The newly developed technology integrates 300 mm thin-wafer technology with packaging innovations, delivering substantial performance enhancements across the entire spectrum of voltage classes. This advancement allows for a significant leap in efficiency and reliability in various applications. These advanced components are available in a diverse range of automotive power packages, each designed to meet specific needs and constraints. The available packages include Single SSO8 (5×6), Dual SSO8 (5×6), mTOLG (8×8), and sTOLL (7×8). Each of these packages offers unique benefits, allowing for greater flexibility and customization in automotive power system design.
They have reduced switching losses. This improvement means that less energy is wasted during the switching process, leading to greater overall efficiency and performance. These components exhibit enhanced Safe Operating Area (SOA) robustness. This robustness ensures that the devices can operate safely under a wider range of conditions, thus increasing their reliability and longevity.The high avalanche current capability of these devices allows them to handle sudden surges in current without being damaged. This capability is crucial for maintaining the integrity and performance of automotive power systems, especially in demanding applications.
Axel Hahn, Senior Vice President and General Manager Automotive LV MOSFETs at Infineon, stated, “Infineon is committed to shaping future technology standards in automotive power MOSFETs in terms of power efficiency and robust power packaging.”
