Answer the following statement(s) true (T) or false (F)
1. A diac can be unidirectional or bidirectional. 2. The operation of the diac is very different to that of a unijunction transistor. 3. There are three schematic symbols for the diac. 4. When voltage is applied to the diac, it will remain in the turned-off state until the applied voltage reaches a predetermined level. 5. The break-back voltage of the SBS is more pronounced than that of the diac.
