Web7 de nov. de 2024 · However, the TRIAC allows the current to flow in both directions. 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. Share Cite Follow Web6 de jun. de 2024 · Bimpelrekkie's math doesn't work, but maybe we can use his idea of the inverse diode. If you replace the triac with an SCR, maintain the same trigger circuit but parallel the gate with a diode.. something like this: simulate this circuit – Schematic created using CircuitLab. That way if the SCR fails short the fuse will blow.
