BSP742T

BSP742T Description

The BSP742T from Infineon Technologies is a high-side power switch designed for automotive and industrial applications, compliant with AEC-Q100 standards. It operates within a wide input voltage range of 5V to 34V, delivering a maximum output current of 1.1A (typical) with a low on-resistance of 260mΩ (max 350mΩ). Packaged in an 8-pin DSO (Tape and Reel), this surface-mount device offers high efficiency with a power dissipation of 1.5W and robust protection features, including current limiting (4A max) and thermal shutdown. Its fast switching (on/off times of 140µs/170µs max) ensures reliable performance in dynamic load conditions.
