The Infineon OptiMOS linear FET is a revolutionary approach to avoid the trade-off between on-state resistance (R DS(on)) and linear mode capability – operation in the saturation region of an enhanced mode MOSFET. It offers the state-of-the-art R DS(on) of a trench MOSFET together with the wide safe operating area of a classic planar MOSFET.

Combination of low R DS(on) and wide safe operating area (SOA)
High max. pulse current
High continuous pulse current
Rugged linear mode operation
Low conduction losses
Higher in-rush current enabled for faster start-up and shorter down time
