breakover voltage การใช้

The SIDAC remains nonconducting until the applied voltage meets or exceeds its rated breakover voltage.
Lightning arresters are rated by the peak current they can withstand, the amount of energy they can absorb, and the breakover voltage that they require to begin conduction.
Unlike a transient voltage suppression diodes, such as Transil, a Trisil acts as a crowbar device, switching ON when the voltage on it exceeds its breakover voltage.
In general, SIDACs have higher breakover voltages and current handling capacities than DIACs, so they can be directly used for switching and not just for triggering of another switching device.
Most DIACs have a three-layer structure with breakover voltage of approximately 30 V . Their behavior is similar to that of a neon lamp, but it can be more precisely controlled and takes place at a lower voltage.
