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 3A with a digital device like a microcontroller or microprocessor then BT131 is the best choice. Pin Configuration: Main Terminal 1 (Pin 1) : Connected to Phase or neutral of AC mains Main Terminal 2 (Pin 2) : Connected to Phase or neutral of AC mains Gate (Pin 3) : Used to trigger the SCR. Features:- 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. Limitation:- Commutation is not required in AC switching circuits because the TRIAC will not latch on the state since the AC voltage reaches zero for every half cycle. Applications:- AC Light dimmers Strode lights AC motor speed control Noise coupling circuits Controlling AC loads using MCU/MPU Ac/DC Power control Light dimmers Washing machines Motor control Hand tools Specifications:- Triac : BT131 Package : TO-92 Peak gate current : 2 A Peak gate power : 5 W On-state voltage : 1.5 V Gate controlled turn-on Time : 2 µs Package Includes:- 1 x BT131 600V - 1A Triac
