Siemens PROFET BTS 733 L1 Datasheet
The PROFET BTS 733 L1 is a smart two‑channel high‑side power switch designed for 12 V DC grounded loads such as resistive and lamp applications. It replaces electromechanical relays, fuses and discrete circuits, offering CMOS‑compatible inputs and extensive diagnostic feedback.
Key specifications include overload and over‑voltage protection, thermal shutdown, reverse‑battery protection, and ESD protection. The device provides on‑state resistance as low as 36 mΩ at 25 °C, turn‑on times of 80‑180 µs, and operates over a temperature range of –40 °C to +150 °C.
