BT137S-600,118

Thyristors - TRIACs

The BT137S-600,118 is a TRIAC, or a three terminal alternating current device, which is a four layer, three terminal semiconductor. It\'s rated for 600 Volts, 10A and a commutation voltage of 118 V. The BT137 is commonly used in AC relays, phase control rectification, motor speed control, dimmer circuits and other similar applications.

Working Principle

A BT137S-600,118 is a three terminal semiconductor component that allows current to flow in either direction. It is constructed in the same way as a normal thyristor, however it has an additional terminal known as the gate that switches the thyristor into conduction.When a voltage is applied to the gate, a current flows through the gate and into the two other terminals, which in turn provide an electric current. The current then passes through the two terminals and back to the gate. The current essentially switches on and off while the gate voltage is applied. This on and off switching of the voltage is known as phase control rectification. The BT137 can be used to control current in AC devices such as lighting applications, motors, AC relays and more. The phase control rectification of the BT137S-600,118 allows for dimming, speed and torque control, as well as power metering.

Applications

The BT137S-600,118 is commonly used in AC relays and phase control rectification applications. It can also be used for speed and torque control, dimming circuits and power metering. The BT137S-600,118 is perfect for AC circuits, as it can be used to limit the current in an AC signal, as well as control and switch the current to and from the circuit.The BT137S-600,118 can be used in high power and industrial applications, as it can support extremely high currents and voltages.
