BCR25RM-12LB#B00

Thyristors, also known as TRIACs (Triode for AC), are a type of controllable semiconductor switch that can control current flow in both directions. The BCR25RM-12LB#B00 is an example of a thyristor used in a wide range of applications including heating, AC motor control and power light dimming. This article seeks to explore the application field and working principle of the BCR25RM-12LB#B00.

Application Field

The BCR25RM-12LB#B00 is a medium-power switch designed for applications requiring AC control between 0.5 and 2.5 Amperes. It is suitable for use with voltages ranging from 230 to 400 volts, and is typically used to activate lamps, heaters and AC motors. This is due to its ability to switch currents of either polarity, making it ideal for many devices that use AC current such as reversible motors. The thyristor is also used in applications requiring precise dimming of residential lighting systems, such as those controlling the light intensity of LED and halogen bulbs.

Working Principle

The BCR25RM-12LB#B00 is a bi-directional switch consisting of two back-to-back thyristors, with the current to be switched flowing in one direction through each. The design of this thyristor allows it to be easily triggered without relying on a continuous current flowing and making it suitable for AC applications. When a trigger voltage is applied to the gate, it reverses the current direction of the thyristor, and the current will continue to flow until the gate voltage is removed. This allows for precise control of the current and voltage, making the switch ideal for applications such as motor speed controllers or dimming systems.

Conclusion

The BCR25RM-12LB#B00 is a type of TRIAC and is a popular choice for a wide range of AC switching applications. Its bi-directional design makes it suitable for switching AC current in either direction, while its control voltage can be easily adjusted to provide precise control of the current and voltage flow. This makes the switch ideal for applications such as lighting systems, AC motors, and heating solutions.
