Thyristors - TRIACs

A triac, or triode for alternating current, is a generic term for a three-terminal electronic switch used for ac signals and devices. As such it resembles two thyristors connected in inverse parallel, but it is more complex than a simple thyristor, and in order to switch it off, a negative voltage trigger is needed, in contrast to the positive voltage needed to turn it on. This makes the triac an ideal switching device for applications such as motor speed control and light dimming.

BT137-800G0TQ is a series of asymmetric or bidirectional triacs. It was introduced by STMicroelectronics in 2008 and is used in a variety of applications such as AC motor speed control, automation and security systems, vending and gaming machines, robotics, industrial and consumer heating controls, power supplies and audio amplifiers. This series is particularly suited for use with high-power loads (up to 800 A), and offers low conduction losses and low gate trigger current. The BT137-800G0TQ triac offers very good thermal stability, with a very tight on-state rms current and gate trigger voltage.

The BT137-800G0TQ triac works by using a bidirectional thyristor, which turns on when the anode is positive with respect to the cathode and a negative gate pulse is applied. When the anode and the cathode are equal, the triac turns off. This type of triac is commonly referred to as an “on-off” triac. The BT137-800G0TQ is a gate-commutated triac, which means that the gate control voltage determines when to turn on and when to turn off the circuit.

One of the main characteristics of the BT137-800G0TQ is its maximum peak off-state voltage, which is typically 800 V. The maximum peak on-state current of the BT137-800G0TQ is 350 mA, with a minimum on-state current of 300 mA. The minimum trigger current of this triac is 25 mA and its on-state voltage drop is typically 7 V.

The BT137-800G0TQ is widely used in applications which require high power switching, such as AC motor speed control and lighting dimming. Because of its ability to switch high power loads, the BT137-800G0TQ is also frequently used in industrial and commercial applications, such as automation and security systems, vending and gaming machines, robotics, industrial and consumer heating controls, power supplies and audio amplifiers.

In addition to its high power output, the BT137-800G0TQ also boasts low on-state losses and fast switching times. This makes it an ideal choice for applications which require fast, efficient and reliable switching of high power loads. It is well suited for applications which require low cost, low power consumption and low EMI emission.

The BT137-800G0TQ is an excellent choice for applications which require fast and efficient switching of high power loads. Its high off-state voltage, low on-state voltage drop and low trigger current enable it to be used in a wide variety of applications, from motor speed control to lighting dimming, automation and security systems, industrial and consumer heating controls, power supplies and audio amplifiers.
