Thyristors – TRIACs

BCR12FM-14LB#FA0 Application Field and Working Principle

Thyristors, also known as TRIACs, are a type of semiconductor device with three main terminals, the gate, main and main terminals. These three terminals are used to regulate and control the current in the circuit. TRIACs are used in both AC and DC applications, providing but not limited to efficient switching, switching angle control, phase angle control and triggering control of SCR or Thyristors. In this article we will be focusing on the application field and working principle of a specific TRIAC, the BCR12FM-14LB#FA0. The BCR12FM-14LB#FA0 is a 600V, 16A, four-layer thyristor, widely used in general motor speed control, agricultural and industrial automation, power supply and motor control, AC and DC motor control, lighting control and various other applications. This four layer TRIAC contains three semiconductor layers, in which the anode, main and gate terminals are used to regulate and trigger current in the circuit. It is also an electronic switch, as it can be triggered and shut down depending on the control signals in the circuit.The BCR12FM-14LB#FA0 works by controlling the passage of current when triggered. The anode is the positive voltage, in an AC circuit it is the peak voltage, and the cathode is the common voltage, which is the ground. Since in AC circuits the voltage between anode and cathode changes continually, this TRIAC allows the regulated passage of current as the voltage varies, which is known as phase control. The gate terminal is used to control the current flow through the TRIAC and is triggered by changing the gate terminal’s voltage, which can be done by connecting a switch to the gate terminal. When the gate voltage is increased beyond the main terminal voltage then the current starts to flow from the main to the anode terminal, controlling the flow and turning on the device. On the other hand, when the gate voltage drops below the main terminal then the current stops and the device is turned off.This TRIAC has a number of other features that make it perfect for a variety of different applications, such as surge protection, temperature protection and short circuit protection. BCR12FM-14LB#FA0 also has a low trigger voltage and low leakage current, indicating its excellent performance in both AC and DC circuits.In conclusion, the BCR12FM-14LB#FA0 is a robust, four layer TRIAC with a range of features that make it suitable for a number of applications, such as motor control, lighting control and industrial automation. It works by regulating the current flow through the device and can be triggered or switched off by controlling the gate voltage. This TRIAC has a number of advantages, such as low trigger voltage and low leakage current, making it the ideal choice for a range of applications.
