BTS3050TFATMA1 Description

Short technical summary and product information.

The BTS3050TFATMA1 from Infineon Technologies is a single-channel smart low-side power switch within a PG-TO252-3 package. This automotive-qualified device is built with an N-channel vertical power MOSFET and is optimized for 12V automotive applications.

 

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. The device offers a nominal load current of 4A and a minimum current limitation of 15A. Its typical on-state resistance is 44mOhm, with a maximum of 100mOhm at 150°C.

 

Integrated protection functions include over-temperature shut-down with automatic restart, current limitation, and over-voltage protection with active clamp. It also provides electrostatic discharge (ESD) protection on the input pin. The switch type is general purpose, with an N-channel output configuration and a 1:1 ratio.

 

The BTS3050TFATMA1 is suitable for resistive, inductive, and capacitive loads, replacing electromechanical relays, fuses, and discrete circuits. It is mounted via surface mount technology and operates within a temperature range of -40°C to 150°C (TJ).
