Thyristors - SCRs - Modules: C781PS Application Field and Working Principle

The C781PS series of thyristors are a type of semiconductor component commonly used for power switching and control. They are comprised of four layers of alternating P- and N-type material, and when a current or voltage is applied to the gate electrode, it switches from the “off” state to the “on” state, conducting current and allowing it to pass through. These SCRs (silicon controlled rectifiers) can be used in motor control, switching circuits, protection systems, and power factor correction.

The C781PS series has a typical blocking voltage of 800 volts, with a current rating of 600 amperes. It is fast acting, with a turn-on delay time of around 50 microseconds, and a very low turn-off time of around 20 microseconds. It also has very low forward and reverse recovery times, which make it suitable for fast switching applications. The C781PS is also capable of withstanding higher inrush currents, and is capable of withstanding temperature and current transients, making it an excellent choice for power switching applications.

The C781PS series is available in a number of different power module configurations, such as a single, dual, and triple SCR module. These modules are designed to be easily mounted and replaced, and can be used in a variety of applications to provide power switching and control. The modules are also available in several different voltage and current ratings, making them suitable for a wide range of applications.

The working principle of the C781PS series is simple. When a given voltage or current is applied to the gate electrode, the device switches from the “off” state to the “on” state and begins to conduct electricity. This allows the current to pass through and control the motor or power circuit that is being controlled. As the current or voltage is decreased, the C781PS series thyristors automatically switch back to the “off” state and stop conducting electricity.

The C781PS series thyristors are versatile devices that can be used in a wide range of applications. The low turn-on and off times, high voltage and current ratings, and temperature and current transients resistance make it a great choice for power switching and control applications. The modules are also easy to mount and replace, and are available in several different configurations.
