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. What is the breakover voltage of a DIAC or SIDAC?
The breakover voltage is the voltage at which the device becomes conductive. It varies depending on the specific device, typically ranging from 30V to 250V for SIDACs.
-
3. What are the typical applications for SIDACs?
SIDACs are commonly used in high-voltage protection circuits, surge protection, and trigger circuits for high-power switching.
-
4. What are the advantages of using DIACs or SIDACs?
They provide reliable triggering mechanisms for thyristors, enhance circuit efficiency, and reduce the need for additional components.
