BTS4141N

BTS4141N Description

The BTS4141N by Infineon Technologies is a high-side power switch from the Classic PROFET series, designed for automotive applications and compliant with AEC-Q100 standards. It integrates a 1-input, 1-output configuration with a 12V to 45V operating range, making it ideal for robust power management in demanding environments. With a maximum output current of 0.7A and low on-resistance (150mΩ typical, 200mΩ max), it ensures efficient power delivery while minimizing losses. The device features current limiting (1.4A max), thermal shutdown, and fast switching (100µs on, 150µs off), enhancing system reliability. Packaged in a 4-pin (3+Tab) SOT-223 with surface-mount compatibility, it suits space-constrained designs.
