Siemens BTS 432 E2 Datasheet
The PROFET® BTS 432 E2 is a smart high‑side power switch designed for 12 V and 24 V DC grounded loads. It integrates a vertical N‑channel power FET with charge‑pump technology, CMOS‑compatible input, and extensive diagnostic feedback, allowing it to replace electromechanical relays in resistive, inductive, and capacitive applications.
Key specifications include a supply voltage rating of 63 V, load‑dump protection up to 66.5 V, on‑state resistance as low as 30 mΩ, and a power dissipation capability of 125 W. The device also features multiple protection functions such as short‑circuit, over‑voltage, under‑voltage, reverse‑battery, and ESD protection, making it suitable for a wide range of industrial and automotive power‑switching tasks.
