1. What is a TRIAC, and how does it differ from an SCR?
A TRIAC is a bidirectional device that can control AC power, effectively working as two SCRs in parallel but in opposite directions. Unlike an SCR, which only conducts in one direction, a TRIAC operates in both directions, making it ideal for AC applications.
-
2. Why do TRIACs require a DIAC for triggering?
DIACs improve the symmetry of TRIAC firing by ensuring consistent triggering voltages in both directions. This reduces harmonic distortion in AC circuits, enhancing performance.
-
3. What are the limitations of TRIACs?
TRIACs are less efficient for high-power or complex control systems due to asymmetric triggering and potential noise issues. They are more suited to low-to-medium power applications.
-
4. What is the significance of the main terminals (MT1 and MT2) in TRIACs?
The MT1 and MT2 terminals are not interchangeable. Correct configuration is critical for TRIAC operation, as gate current must flow relative to MT2.
