BT136 Equivalent TRIAC BTA08-600B Other TIRACs BT139, BTA16, BT169, Q4008 BT136 TRIAC Overview The BT136 is TRIAC with 4A 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. So if you looking to switch of control (dim, speed control) an AC load which consumes less than 6A with a digital device like microcontroller or microprocessor then BT136 might be the right for you. How to use BT136 There are many different ways to use a TRIAC, since the device is bi-directional the TRIAC gate can be trigger with either positive voltage or negative voltage. So this allows the TIRAC to be operated in four different modes. You can read this?article?if you want to know more about the switching modes. A simple TRIAC switching circuit is shown below. In this circuit the TRIAC can be turned using the switch, when the switch is pressed the
