Infineon BTS4141N Series Power Switch IC, 1.4W Power Rating, 0.7A Operating Current - BTS4141NHUMA1

This power switch IC is a high-side switching device designed for automotive environments, offering controlled distribution of power to multiple loads while operating across a wide temperature range. It is intended for surface-mounted applications where compact, transistor-like switching is required and supports protected switching behaviour suitable for vehicle electrical systems.

Features and Benefits:

• 45V maximum supply voltage allows robust load-source margins
• 0.7A operating current supports moderate current loads
• 320mΩ Rds(on) minimises conduction losses at switch-on
• 1.4W power rating enables continuous dissipation handling
• -40 to 125°C operating range sustains harsh temperature extremes

Applications

• Suitable for switching vehicle auxiliary circuits and sensors
• Ideal for powering cabin lighting and small actuators
• Used with distributed electronic modules in automotive systems
• Can be used for protected supply feeds in control units
