Thyristors are a well-known and reliable semiconductor device. They are often used in various applications from power control to motor drives. The BT145-800R,127 is a type of thyristor that is commonly used for high power applications. This article will discuss the application field and working principle of the BT145-800R,127.

The BT145-800R,127 is a high power trigate thyristor that is suitable for use in many high power situations. It has a rated blocking voltage of 800V, and a peak repetitive off-state voltage of 800V. It is commonly used in applications including AC and DC motor drives, power factor correction, and AC switching. The BT145-800R,127 is an ideal choice for these high power applications due to its high performance and reliability.

The working principle of the BT145-800R,127 is based on the thyristor effect. In a simple explanation, thyristors are three-terminal devices that can carry current in either direction. By controlling the voltage applied to the gate terminal, the anode current can be turned on and off. This is referred to as the gating action of the thyristor, and it is what makes it so useful in power control applications.

In the BT145-800R,127, the gating action is based on the current level applied to the gate. When the current level is higher than a certain threshold, the gate voltage will turn the thyristor on, allowing the current to flow. When the current drops below the threshold level, the gating action turns the thyristor off, stopping the current flow.

The BT145-800R,127 is a high power thyristor that is suitable for many high power applications. It has a high blocking voltage and a peak repetitive off-state voltage of 800V. It is commonly used for AC and DC motor drives, power factor correction, and AC switching. Its working principle is based on the thyristor effect, in which the current level applied to the gate determines whether or not the thyristor is turned on or off.
