BTS133BKSA1 Description

Short technical summary and product information.

The Infineon Technologies BTS133BKSA1 is a smart N-channel vertical power FET in a Smart SIPMOS® chip-on-chip technology, providing embedded protection functions. It is suitable for switching or linear applications with resistive, inductive, and capacitive loads, and serves as a microcontroller-compatible power switch for 12V and 24V DC systems.

 

Key electrical specifications include a drain source voltage of 60V, a nominal load current of 7A, and a typical on-state resistance of 40mΩ. The device features logic-level input, input protection (ESD), thermal shutdown with latch, short circuit protection, overload protection, and overvoltage protection. It also offers status feedback with an external input resistor and allows for analog driving.

 

Packaged in a TO-220-3 through-hole configuration, the BTS133BKSA1 operates within a temperature range of -40°C to 150°C. Its integrated protection mechanisms make it a reliable replacement for electromechanical relays and discrete circuits in various automotive and industrial applications.
