1. How do DIACs differ from SIDACs?
DIACs exhibit symmetrical voltage thresholds in both directions, while SIDACs often have higher breakover voltages and are suitable for applications requiring higher current capacities.
-
2. How do I select a DIAC or SIDAC for my application?
Key parameters include the breakover voltage, peak current, holding current, and the type of package. Selection should match the application's voltage and current requirements.
-
3. What packages are available for DIACs and SIDACs?
Common package types include DO-15, TO-92, and axial configurations, catering to different mounting and thermal management needs.
-
4. Can DIACs or SIDACs be replaced by other components?
While other semiconductor devices can sometimes be adapted, DIACs and SIDACs are optimized for their specific functions, making them difficult to replace directly in most designs.
