1. What are DIACs and SIDACs used for?
DIACs and SIDACs are used as triggering devices in AC phase control applications, such as light dimmers, motor speed controls, and heater controls. They help in controlling the current flow by switching at a specific voltage threshold.
-
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 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.
