BTS50055-1TMC Description

Short technical summary and product information.

The Infineon BTS50055-1TMC is a smart high-side power switch belonging to the Classic PROFET™ 12V family. It is designed for 12V DC grounded loads, offering integrated protective functions such as overload, current limitation, short circuit, overtemperature, and overvoltage protection.

Key electrical characteristics include an operating voltage range of 5.0 to 34 V, a low on-state resistance of 6.0 mΩ, a nominal current of 17 A, and a load current (ISO) of 70 A. It also features a short circuit current limitation of 130 A and a current sense ratio of 14000:1 for diagnostic feedback.

This device is suitable for loads with high inrush current, such as lamps and motors, and can replace electromechanical relays, fuses, and discrete circuits. It is housed in a PG-TO220-7-4 package suitable for through-hole mounting.

The BTS50055-1TMC is AEC qualified and RoHS compliant, making it a reliable choice for automotive power switching applications.
