Linear FET Delivers Low RDS(on) Plus Large SOA

Infineon Technologies AG has launched the OptiMOS™ Linear FET series. This new product family combines the state-of-the-art on-state resistance (RDS(on)) of a trench MOSFET with the wide safe operating area (SOA) of a planar MOSFET. This solves the trade-off between RDS(on) and linear mode capability.

The OptiMOS Linear FET can operate in the saturation region of an enhanced mode MOSFET. It is the perfect fit for hot-swap, e-fuse, and protection applications commonly found in telecom and battery management systems (BMS).

Both, the rugged linear mode operation and the higher pulse current contribute to low conduction losses, faster start-up, and shorter down time. The OptiMOS Linear FET prevents damage at the load if there is a short circuit, by limiting high in-rush currents.

The OptiMOS Linear FET is available now in three voltage classes: 100V, 150V, and 200V. They can be supplied in either a D²PAK or D²PAK 7pin package. These industry standard packages offer a compatible footprint for drop-in replacement.
