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. Can DIACs and SIDACs be used in DC circuits?
No, DIACs and SIDACs are designed specifically for AC circuits as their operation relies on alternating voltage polarities.
-
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. How does temperature affect DIACs and SIDACs?
Their operation is temperature-dependent, with most devices rated for operation between -40°C and 125°C. Higher temperatures can affect their triggering voltage.
