Infineon Technologies AG extends its OptiMOS™ 5 portfolio with 80 V and 100 V variants.

Infineon Technologies AG extends its OptiMOS™ 5 portfolio with 80V and 100V variants. This latest generation of Power MOSFETs is optimized for high switching frequencies especially used in synchronous rectification applications for telecom and server power supplies as well as in industrial applications such as solar, low voltage drives and power adapter. The new OptiMOS 5 MOSFETs offer the industry's lowest on-state resistance (RDS(ON)) - up to 45% reduction for 80 V and up to 24% reduction for 100 V compared to the previous generation. Due to the lower resistance there is significantly less need to parallel parts resulting in reduced material cost. The newly introduced generation offers the highest levels of power density and energy efficiency.

In comparison to the previous generation, the OptiMOS 5 80V variant offers 38% reduction in output charge and the OptiMOS 5 100V variant a 25% reduction. Less output charge means reduced switching 

losses and lower voltage overshoot in hard switching topologies and synchronous rectification. This results in faster design and lower development costs. Moreover, the reduction in gate charge of 24% for 80V and 29% for 100 V also reduces switching losses especially at light load operation and in applications requiring high efficiency throughout the whole load range, such as micro-inverters and power optimizers for solar applications.

OptiMOS5 80 V and 100 V are offered in seven different packages: SuperSO8, S308, TO-Leadless, TO-220, TO-220 Full PAK, D²PAK and D²PAK 7Pin with RDS(ON) ranging from 1-4 mW, 4-8 mW and 8-2 mW for 80V and 1-4 mW, 4-8 mW and 8-10 mW for 100 V. Samples are available in both voltage classes and all packages. Products are in volume production.
