Product Description
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.
