Thyristors - TRIACs

A Thyristor-TRIAC is a three-terminal solution consisting of a PNPN or NPNP structure. It is designed to overturn AC current in both directions. The main purpose of a TRIAC is to control the amount of current being switched on and off in an alternating current circuit. TRIACs are widely used due to their ability to handle high currents easily when compared to other switches as well as cost effectiveness.

The BTA408-800ETQ is a popular three-terminal device from STMicroelectronics. It is a TRIAC capable of controlling alternating current flows. It is used in various applications including appliance control, power supplies, heating and cooling, and more. It has a wide range of features that make it suitable for many applications. The key features of the BTA408-800ETQ include a load current rating up to 8 A, an on-state current of up to 800 mA, a logic level gate input, and a voltage blocking capability up to 800 V.

In addition to these features, the BTA408-800ETQ also provides reverse blocking protection up to 800 V, which prevents unwanted currents from entering the circuit. The device also has an on-state current limit of 800 mA and a peak non-repetitive surge current of 25 A. This helps to provide protection to the TRIAC from overcurrents in the circuit. The device can also be used with a wide range of loads, including resistive, capacitive, inductive, and mixed-load types.

The working principle of a TRIAC is relatively simple. When the gate input of the device receives a signal, a signal is sent to the main terminals of the TRIAC, allowing current to flow in both directions. This is done by creating a field of ions between the two main terminals, which causes a flow of current through the device. The current can be controlled by adjusting the gate input signal.

The BTA408-800ETQ is well-suited for a variety of applications due its wide range of features and flexibility. It can be used in various applications, from controlling lighting and appliances, to controlling the current in power supply circuits. It is also an economical solution for many applications, as it is relatively low-cost compared to other types of thyristors.
