BTS3125TFATMA1 Description

Short technical summary and product information.

The Infineon Technologies BTS3125TFATMA1 is a 125 mΩ single-channel smart low-side power switch housed in a PG-TO252-3 package. Optimized for 12V automotive applications, this device is built with an N-channel vertical power MOSFET and is monolithically integrated.

 

Key electrical specifications include an operating voltage range of 0-31V, a maximum load voltage of 40V, and a maximum input voltage of 5.5V. It offers a nominal load current of 2A and a minimum current limitation of 7A. The maximum on-state resistance is 250 mΩ at TJ = 150°C, with a typical value of 108 mΩ. The maximum OFF state load current at TJ ≤ 85°C is 0.6 µA.

 

This smart power switch provides several embedded protection functions, including over-temperature shut-down with automatic restart, current limitation, and active clamp over-voltage protection. It is suitable for switching resistive, inductive, and capacitive loads, replacing electromechanical relays, fuses, and discrete circuits. The device is AEC Qualified and RoHS compliant.

 

The BTS3125TFATMA1 is designed for surface mount installation in a TO-252-3 package. Its operating temperature range is -40°C to 150°C (TJ).
