The BT131 is TRIAC with 1 A maximum terminal current. The gate threshold voltage of the BT131 is also very less so can be driven by digital circuits. Since TRIACs are bi-directional switching devices they are commonly used for switching AC applications. To switch off control of an AC load that consumes less than 3 A with a digital device like a microcontroller or microprocessor then BT131 is the best choice.
