The BT136 is TRIAC with 4 A maximum terminal current. The gate threshold voltage of the BT136 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 6 A with a digital device like a microcontroller or microprocessor then BT136 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 BT136 is a 4 amp which can be used as like switch for your home electric appliance which is 220 V operated We can use it to control the switch of your fan, led light
