IRKT105/12A

IRKT105/12A Application Field and Working Principle
The IRKT105/12A module is a semiconductor device that belongs to the thyristors or SCRs (silicon-controlled rectifiers) family. It is used for power switching in single-phase applications and comes with a triggering (gate) capacity. This module is designed for industrial, commercial, and residential applications, such as in adjustable speed drives, heater controls, and inverters.

In a single-phase circuit, the IRKT105/12A module consists of three parts -- the control/gate electrode, the cathode, and the anode. The control/gate electrode is connected to the lead of a current source that is used to trigger or activate the module. When the gate current is applied, the output of the module is switched on, allowing current to pass through the module.

Once the module is activated, the anode and cathode are connected and current passes through it. When the current is interrupted by its source, the module switches off and the anode and cathode are disconnected. The IRKT105/12A module provides high efficiency and speed in controlling the power switching process.

Depending on the application, different models of this module are available in various voltage and current ratings. Some have built-in diodes, while others have an external diode. The IRKT105/12A module is hermetically sealed, so it can be used in hostile environments. It features an insulation rating of 850 Vac, a non-polar operation and positive temperature coefficient.

The IRKT105/12A module is an economical and reliable choice when it comes to high-power switching. It can be used for applications involving large currents and is easily triggered. In addition, it provides fast and high-efficiency switching, resulting in minimal power losses. All these features make it suitable for a broad range of applications from industrial to residential.
