Why can electricity flow only in one direction through a diode?

WebLike the diode, the Thyristor is a unidirectional device, that is it will only conduct current in one direction only, but unlike a diode, the thyristor can be made to operate as either an open-circuit switch or as a rectifying diode depending upon how the thyristors gate is triggered. In other words, thyristors can operate only in the switching ... WebApr 18, 2024 · The DIAC is an abbreviation for Diode AC semiconductor switch. The prefix ‘Di’ indicates, that the device has two terminals like diode. ‘AC’ means that the device controls the alternating current (a.c.) or can conduct current in either direction. In the thyristor family, the DIAC is used most commonly as a triggering device to trigger ...
