Siemens BTS 941 Smart Lowside Power Switch Datasheet
The BTS 941 is a N‑channel vertical power FET designed for low‑side switching of 12 V and 24 V DC loads. It replaces electromechanical relays and offers integrated protection functions such as over‑voltage, overload, short‑circuit, ESD, and thermal shutdown, making it suitable for resistive, inductive, and capacitive applications.
Key specifications include a 60 V drain‑source voltage rating, 12 A nominal load current, on‑state resistance as low as 31 mΩ at 25 °C, and a power dissipation capability of 149 W. The device also features adjustable current limiting, current sensing, and status feedback via external resistors.
