1. 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.
-
2. 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.
-
3. 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.
-
4. What are the key parameters to consider when selecting a TRIAC?
Important factors include voltage and current ratings, dv/dt capability, gate sensitivity, and application-specific requirements like power dissipation and thermal management.
