T7H8126504DN

Thyristors, also known as Silicon Controlled Rectifiers (SCR), are power controlling devices used in many industries. A Thyristor module, like the T7H8126504DN, is composed of two thyristors in one package. It is primarily used for the control of high power applications, such as electric heating.

A typical SCR is a three-terminal semiconductor device with a gated, an anode and a cathode. A SCR can act as a switch, allowing current to flow through when an electric current passes through it in one direction while blocking the flow of current when it passes in the opposite direction. This makes it ideal for on/off type of applications.

When it comes to T7H8126504DN, it is a type of 4-terminal SCR module, featuring two thyristors connected in inverse parallel. It has a maximum blocking voltage of 800 volts and a maximum current rating of 12A. This module also has an on-state voltage drop of 2.2 volts and a maximum pulse gate current rating of 5mA.

The T7H8126504DN module finds application in many industries including the food and beverage industry. It can be used for controlling electric heaters, and is also suitable for the switchable control of electrical motors, lamps and other electrical devices. It is also ideal for safety applications, where an over-current needs to be prevented.

In terms of its working principle, current flowing through the SCR module is controlled by applying and removing a gate voltage while the main current is passing through. When the gate voltage is between 0 to 0.6 volts, current flows through the thyristors in the T7H8126504DN and then is continued on through the output circuit. When the gate voltage is above 0.6 volts, then the thyristors switch off, preventing the current from flowing.

All in all, T7H8126504DN is a popular SCR module, suitable for controlling high power applications such as electric heaters and motors. It is composed of two thyristors, connected in inverse parallel, and works by applying and removing a gate voltage, while the main current is passing through.
