Thyristors - TRIACs are a group of semiconductor devices employed in power control and electrical power conversion. The BT137X-800E,127 is a part of this group that is made of two thyristors and offers the capability of high-voltage, high-current and low-cost applications.

The main principle of the thyristor is to control the current through a controlled gate. When a negative voltage is applied to the gate of the thyristor, the current is cut off and the thyristor is turned off. Conversely, when a positive voltage is applied, the current flows and the thyristor is turned on.

The BT137X-800E,127 is a four-terminal thyristor with two thyristors connected in series. It can be used mainly in applications such as motor control, HVAC, induction heating, and lighting control. Additionally, it can also be used in power switching circuits for industrial, commercial, and residential applications.

In motor control, the BT137X-800E,127 can be used as a starter in a three-phase system. It has two thyristors connected in series, one at each of the three terminals serving as the starter. The third thyristor, connected between two of the three starter terminals, can be used as the load switch. When the start switch is activated, the voltage applied to these two starter terminals will be increased, causing the load thyristor to be activated. This will then cause the current to flow through the motor, allowing the motor to start running.

In HVAC control, the BT137X-800E,127 can be used for controlling motors for zone airflow control by controlling the motor speed. The same principle can be applied to induction heating, where the speed of the motor is modulated to regulate the temperature. In lighting control, the same principle can be employed for switching on loads in a controlled manner.

The BT137X-800E,127 is also suitable for power switching circuits and can be used for switching power up to 800V and 200A. It can be employed for DC-DC conversion, AC-DC conversion, rectification, and other power conversion applications. The two thyristors connected in series make it suitable for usage with high-voltage circuits, providing more reliable and efficient power control.

In summary, the BT137X-800E,127 is a part of the Thyristors - TRIACs family and can be used in several power control and electrical power conversion applications. Its two thyristors connected in series make it especially suitable for high-voltage and high-current applications, while its low cost makes it a cost-effective solution for various projects.
