Infineon has expanded the application scope of its OptiMOS power MOSFET portfolio by introducing a family of 200 V and 250 V devices for synchronous rectification in 48 V systems, DC-DC converters, uninterruptible power supplies (UPS) and inverters for DC motor drives. The devices feature very good FOM (Figure of Merit) and enable overall efficiency levels exceeding 95%. They offer very low on-state resistance, which translates to low power losses in high-current applications. Low gate charge contributes to low losses and fast switching in switched mode applications like isolated DC-DC converters for telecom applications.
The operating characteristics of the OptiMOS 200 V and 250 V family allow use of a slim SuperSO8 package (5 x 6 x 1 mm) for applications that previously required bulky D²PAK devices (9 x 10 x 4,5 mm). Additionally, using leadless packages like SuperSO8 provides enhanced switching behaviour and high efficiency levels.
