Thyristors - TRIACs

A TRIAC is a type of thyristor, a three-terminal semiconductor device that contains three alternating current (AC) current switches. It is used in applications where control of AC power is necessary, such as switching high power electric motors, controlling the speed of fans, regulating temperature in industrial processes, and controlling the power supply to appliances. The BT137-600G0Q TRIAC is a top-of-the-line device designed for AC and DC applications.

Applications and Uses of BT137-600G0Q

The BT137-600G0Q TRIAC is suitable for control circuits and low power AC systems. It is a 600V device and can handle up to 8A at a continuous forward blocking voltage of 600V. It is often used in solid-state relays, temperature controllers, and AC power switching devices. It can be used as either an SCR or a thyristor.

Working Principle of BT137-600G0Q

The BT137-600G0Q is a thyristor, which is basically a three-dimensional switch that uses an electrostatic charge to control an electric current. When a positive voltage is applied to the gate terminal of the TRIAC, the thyristor activates and its switch is turned on, allowing electric current to flow. When the voltage is removed, the switch turns off and the current stops flowing. The TRIAC can be triggered in two different ways, either by a one-shot pulse that activates the switch when it is applied or by a continuous pulse which keeps the switch on until the voltage is removed.

The BT137-600G0Q TRIAC has an 8A continuous forward blocking voltage, which allows the TRIAC to be used in high power AC applications. In addition to its high current handling capability, the TRIAC also has a turn-off time of 2 µS or less. This makes it ideal for fast switching applications, such as motor speed control, power supply regulation, and temperature control.

Conclusion

The BT137-600G0Q is a top-of-the-line TRIAC designed for AC and DC applications. It has an 8A continuous forward blocking voltage and a turn-off time of 2 µS or less, making it suitable for fast switching applications. Its 600V rating also allows it to be used in high power AC applications. The BT137-600G0Q is an ideal choice for applications such as solid-state relays, temperature controllers, and AC power switching devices.
