Infineon Technologies AG has introduced its new OptiMOS™ 8 100 V power MOSFET technology, designed to address the increasing power handling requirements driven by megatrends such as green mobility, robotics, and artificial intelligence. The latest generation of OptiMOS technology incorporates application-specific optimizations for RDS(on)-focused applications, including motor control systems and battery protection solutions.

Compared to the previous OptiMOS 5 generation, the new OptiMOS 8 100 V technology delivers up to 44% lower RDS(on), improving both performance and cost efficiency. According to Infineon, these improvements enable up to 18% higher peak current output in motor drive inverter applications, establishing a new benchmark for this class of devices.

For static switching applications such as battery protection circuits in battery management systems (BMS), the reduced RDS(on) supports higher power density, lower component count, and improved thermal performance.

As AI data centers continue to expand and operate at higher power levels, battery backup units (BBUs) are facing increasing power density requirements. Infineon states that the OptiMOS 8 100 V technology is designed to support these demands by enabling higher power density in high-power BBU systems.

The new MOSFET family features a tightly controlled threshold voltage variation (ΔVGS(th)) of less than 0.8 V combined with low transconductance (gfs), characteristics that contribute to optimized current sharing and enhanced system reliability.

To address a broad range of end applications, the OptiMOS 8 100 V portfolio is offered in multiple package options, including clip-based packages such as the TOLL with Copper Clip and the established SuperSO8 5×6 package. These package technologies are designed to provide improved thermal performance while supporting compact system designs.

Infineon has also introduced a reference design demonstrating the capabilities of the new technology in a practical application. The design combines OptiMOS 8 100 V MOSFETs with XENSIV™ TMR current sensors and a PSOC™ Control C3 microcontroller to implement field-oriented control (FOC) for battery-powered drone applications. The platform is designed as a ready-to-use solution for electronic speed controller (ESC) development.

The OptiMOS 8 100 V product family will be available beginning in June.
