Thyristors or silicon controlled rectifiers (SCRs) are 3-pin semiconductor devices used as electronic switches typically for controlling power as outputs from power supplies and for motor speed control and dimming lights. DIACs, SIDACs and TRIACs are all thyristors, but there are also other types such as gate turn off (GTO) thyristors and SCR modules. K2502GRP thyristor bridges and modules provide multiple thyristors in one circuit, and are commonly used in high-current applications such as welding and electric motors. This article will discuss the application fields and working principles of K2502GRP thyristor bridges and modules.

K2502GRP thyristor bridge and module circuits allow current to flow through the thyristors in either direction via a single momentary pulse of electricity. This feature makes them ideal for applications that require rapid switching of high currents such as dimmer switches. The K2502GRP is a 12 pin module that consists of 6 thyristors providing three channels of power regulation, each rated for up to 250 amps. This makes it suitable for welding and other high current applications. The K2502GRP offers superior power efficiency, low voltage losses, and low on-state resistance for better load handling.

The K2502GRP is based on the DIAC thyristor technology. This is a two-terminal device that allows for current to flow in both directions when triggered. It does this by applying a positive voltage to one of its two terminals, which increases the current in both directions until the voltage difference between the two terminals exceeds a certain level. At this point, the current in the opposite direction will start to decrease and the thyristor will switch off. This is known as the breakover voltage. The breakover voltage of the K2502GRP is between 70V and 490V. This means that it can be used in a wide range of applications. However, its rated current should not be exceeded.

The K2502GRP thyristor bridge and module works by using the DIAC thyristors to provide 3 different output channels each with a different current rating. It does this by connecting a pair of thyristors in opposite directions in each channel, with one thyristor connected to the positive supply and the other to the negative supply. When a brief pulse of energy is applied to the input, the thyristors will simultaneously turn on, providing a single momentary output. When the pulse of energy is removed, the thyristors turn off. This can be used in applications such as motor speed regulation, lighting dimmers, and other power supplies.

In summary, K2502GRP thyristor bridges and modules are commonly used for high current applications such as welding and electric motors. They are based on DIAC thyristor technology and provide 3 channels of power regulation with different current ratings up to 250 amps. The device operates by applying an input signal which causes the thyristors to turn on simultaneously, providing a single momentary output. Once the input signal is removed, the thyristors turn off. These devices are ideal for applications such as motor speed regulation, dimmer switches and other power supplies.
