Thyristors - TRIACs

Thyristors are a type of semiconductor device typically used for controlling electrical power in a wide range of applications. The name comes from the combination of Greek words for \'Thyristor\', meaning one who does things, and \'Transitions\', meaning to change. They are commonly used in applications that require current or voltage control from very low levels up to several hundred amps. One of the more common types of Thyristors is the TRIAC, which stands for Triode for Alternating Current.

The ACTT2S-800ETNJ is a type of Triode for Alternating Current (TRIAC). It is a high-efficiency Thyristor designed for applications such as 3-phase motor control, static switching, static converter, zero-cross and AC-DC conversion. It features a wide voltage range of up to 800V and a high current capacity of up to 800A, enabling it to be used in a variety of industrial and commercial applications.

Application Field and Working Principle

The ACTT2S-800ETNJ is used in a range of applications that require electrical switching, including: motor control, static switching for loads such as resistive/capacitive, and AC-DC conversion. In all of these applications, the ACTT2S-800ETNJ is used to switch between two states, allowing electrical current to pass through the device during one state and preventing it from passing during another.

The working principle of the ACTT2S-800ETNJ is based on the principle of a Thyristor. The device is constructed from three p-n junction layers, appropriately biased. When the gate voltage is applied, the first p-n junction is turned on, allowing current to flow through the device. The second p-n junction turns on when the voltage reaches a certain level, allowing the current to pass through both junctions simultaneously and providing for a controlled flow of current. Depending on the type of TRIAC device being used, either steady-state or zero-crossing, the current can be pulsed or maintained at a fixed level.

The ACTT2S-800ETNJ is also fitted with an overload protection circuit which prevents it from being driven beyond its rated current. This prevents the device from being damaged due to excessive current, while still allowing it to be used in applications that require higher than normal current levels.

The ACTT2S-800ETNJ is a reliable and efficient Thyristor, suitable for a wide range of applications that require electrical switching, motor control, static switching, or AC-DC conversion. It features a wide voltage range of up to 800V and a high current capacity of up to 800A, making it one of the best choices for high-power applications. Additionally, its overload protection circuit prevents damage from high current levels, making it an ideal solution for applications requiring higher than normal current levels.
