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.


  • It has a highly sensitive gate
  • It is suitable for uses in mains appliance control
  • BT131 is a 1 amp which can be used as like switch for your home electric appliance which is of 1.5 V operated We can use it to control the switch of your fan, led light.
