Working Principle:

The BT137B-800F,118 thyristor follows a gate-controlled principle, in which conduction through the device is controlled by a gate pulse applied to the gate terminal. When the forward bias across the thyristor’s main terminals is applied, it will begin to conduct and allow current to pass through. By applying a gate pulse during the forward current, the gate terminal can be used to further control the thyristor’s conduction, allowing for precise and accurate regulation of the current passing through the device. This type of thyristor can be used to switch power in both directions, which is useful in AC-power control applications where bidirectional current flow is required.
