BTS133,Smart Low-Side Power Switch IC,TO-220

The BTS133 is a high-performance smart low-side power switch designed to replace electromechanical relays and discrete circuits in modern electronic systems. Encased in a TO-220 package, it integrates advanced protection features such as thermal shutdown, overcurrent limitation, and overvoltage protection to ensure safe and reliable operation.

With a nominal load current of 7A and a current limit of 21A, the BTS133 is ideal for driving resistive, inductive, and capacitive loads. Its low RDS(on) value of 50mOhm ensures minimal power loss, while the integrated status feedback and logic-level input simplify system design. This versatile power switch is suitable for automotive, industrial, and consumer electronics applications.
