How a diode works with triac

WebThe diode is a two-element semiconductor device containing an anode and a cathode and providing unidirectional conduction. A diode allows the current to flow in one direction but not the other. Many types are used in such devices as rectifiers, detectors, peak clippers, mixers, modulators, amplifiers, oscillators and test instruments. Web9 de jul. de 2024 · Abstract. Triac is a three terminal AC switch which is different from the other silicon-controlled rectifiers in the sense that it can conduct in both the directions that is whether the applied ...

Web5 de nov. de 2024 · Connect triac MT1 to your 0V. To switch the triac on, switch the gate to -5V through 470Ω which limits the gate current to 10mA. You can do this with a transistor or even a 74HC logic gate. Connect the load between MT2 and the other terminal of your 24V supply i.e, not the one you just called 0V. Done.

That's why the anodes (or M ain T erminals) are taken from both P and N materials. And the gates are taken from both P and N materials so that the TRIAC can be triggered with either polarity gate-cathode voltages or either polarity gate currents.
