Infineon expands OptiMOS 6 portfolio
Infineon has expanded its OptiMOS 6 portfolio by introducing the automotive 150 V MOSFET family to meet the demanding requirements of modern electric vehicles and are available in three advanced package options: TOLL, TOLG, and TOLT.
The new automotive MOSFET family, based on Infineon's 6th generation OptiMOS technology, offers two different drain-source resistance levels across all device variants. All variants are rated for the 150 V voltage class and deliver the lowest RDS(on) available in this class, reaching as low as 2.5 mΩ. This enables minimal conduction losses and excellent efficiency.
According to the company, the tight distribution of the gate threshold voltage (VGS(th)) supports optimal synchronisation when multiple MOSFETs are used in parallel configurations, which is particularly relevant for high-power automotive systems. T
he devices also feature low switching losses up to high frequencies, allowing for highly efficient operation in fast-switching applications such as modern DC/DC converters. In terms of thermal performance, the variants achieve a thermal resistance as low as 0.4 K/W. This significantly improves heat dissipation, reduces system-level cooling requirements, and lowers associated expenses.
Each of the three package types offers specific advantages: the TO-Leadless (TOLL) 10x12 mm² enables a compact design. The 10x12 mm² TOLG package is footprint-compatible with TOLL, with the additional feature of gullwing leads for high robustness against thermal-mechanical stress. Meanwhile, the 10x15 mm² TOLT package features a top-side cooling concept that enables efficient heat dissipation on system level, making it well-suited for thermally demanding applications in space-constrained environments.
Infineon says its OptiMOS 6 150 V MOSFETs are qualified to the highest standards of Infineon Automotive Quality and exceed the requirements of the AEC-Q101 standard. In addition, they are PPAP-capable, making it easy to meet the highest automotive production standards.
