Infineon Technologies has introduced its new OptiMOS™ 7 series of power MOSFETs. Designed with a clear application-oriented philosophy, the series offers specialized solutions for key market segments, aiming to set a new benchmark in power conversion efficiency and performance.
The series is segmented to address distinct challenges:
-
Switching-Optimized: For data centers and servers, this variant features a 25% improvement in FOM and utilizes a Source Down package for superior thermal performance, reducing power loss in high-load AI and telecom applications.
-
Motor Drive-Optimized: Designed for power tools and garden equipment, it offers a 3x improvement in Safe Operating Area (SOA) and a 70% increase in transconductance for greater reliability and efficiency.
-
Conduction Loss-Optimized: Aimed at battery management systems (BMS) and 12V SMPS, this type reduces conduction losses by up to 40% compared to the previous OptiMOS™ 6 generation.
-
A Dedicated 25V Family: A key highlight is the 25V product group specifically optimized for 48V Intermediate Bus Converters (IBC) in AI servers and telecom equipment. It offers up to 20% lower RDS(on) and 25% better FOM than its predecessor and is available in advanced PQFN 3.3x3.3 packages with bottom-side or dual-side cooling, rated for 175°C.
The series provides a comprehensive "family" of package options, including SuperSO8, SuperSO8 with top-side cooling, and various PQFN form factors (3.3x3.3 and 2x2), allowing designers to select the optimal balance of size, thermal performance, and layout flexibility for their end product.
ICgoodFind's Insight
Infineon's launch of the OptiMOS™ 7 series, particularly its application-targeted variants like the 25V family for AI power delivery, demonstrates a strategic shift from general-purpose components to precision-engineered solutions. This approach directly addresses the complex efficiency and thermal demands of modern high-performance electronics.
