Thyristors - TRIACs is a type of semiconductor device which is popularly known as a three terminal silicon switch. It is also known as bidirectional triode thyristor (BTT) or triode thyristor (TRIAC) and is often applied in AC circuits. This type of device is an analogy to the diode but it is even more useful than diode, allowing the control of current in both directions. It is used to control the power in AC circuits at a certain load and thus provide protection for the device from overloading. The BT137-600-0TQ is one such thyristors – TRIACs and its application and working principle are discussed in this article.

The BT137-600-0TQ is an individual thyristor – TRIACs. It is a zero-voltage turn-on (ZVT) device which offers excellent characteristics of low gate control power and several trigger modes for dynamic operation. It has three terminals, the main two being the main terminal (M) and the gate terminal (G), and the third one being the zero-gate voltage terminal (Z). The current of BT137-600-0TQ is controlled by the gate like other thyristors, but in the case of BT137-600-0TQ the gate voltage is used to trigger the switching.

The BT137-600-0TQ can be used in a wide range of applications and is suitable for controlling AC loads. It is used in AC voltage controllers, motor control, power converters, power supplies, electric equipment and many other applications. It provides a low on-time delay and improved thermal stability in order to achieve excellent power control performances. The BT137-600-0TQ is designed to withstand the high ambient temperatures, so it can be used in a wide range of no-load and load conditions.

The working principle of the BT137-600-0TQ is based on the well-known principle of triggering devices, which is to provide a gate signal to trigger the switching process. The gate voltage is used to activate the thyristor and the current will flow in both directions. In the case of the BT137-600-0TQ, the zero-gate voltage terminal (Z) is used to monitor the gate current and it is designed to control the on/off state of the device. The BT137-600-0TQ can also provide a low voltage drop due to its low on-time delay combined with its low gate voltage trigger.

In conclusion, the BT137-600-0TQ is a thyristor – TRIACs which has the capability to provide a low voltage drop, low on-time delay and improved thermal stability. It is suitable for controlling AC loads and is used in a wide range of applications such as AC voltage controllers, motor control, power converters, power supplies, and electric equipment. The BT137-600-0TQ works on the principle of zero-voltage switch on/off process and its gate voltages are used to trigger the switching process.
