BT-136 is 4A, Triac. Glass passivated triacs in a plastic envelope, intended for use in applications requiring high bidirectional transient and blocking voltage capability and high thermal cycling performance. Typical applications include motor control, industrial and domestic lighting, heating and static switching.

A Triac is a type of solid-state AC switch that can be triggered on and off at any point in the AC waveform. It is commonly used for phase control applications such as dimming lights or controlling the speed of AC motors.

Triacs are similar in operation to thyristors, but unlike thyristors, triacs can switch both polarities of the AC waveform.

A triac consists of three layers of alternating P-type and N-type semiconductor material, arranged in a symmetrical structure. When the gate of the triac is triggered, it becomes conductive, allowing current to flow through the device. The triac will continue to conduct until the current falls below a certain threshold value, at which point it will turn off.

Triacs are widely used due to their high-power handling capability and low cost, making them a popular choice for industrial and consumer applications where AC switching is required. They are also used in applications where fast switching is needed, such as in switching power supplies, since they can switch on and off very quickly.
