BSP171I

Active and preferred

OptiMOS™ P-channel power MOSFETs are ideal for load switches, battery management, and reverse polarity protection applications. The main advantage of OptiMOS™ P-channel power MOSFETs is the simplified design complexity in medium and low power applications. Its easy interface to Microcontroller Unit (MCU), fast switching, and avalanche ruggedness, makes Infineon’s OptiMOS™ power MOSFETs suitable for applications demanding high-quality.
