Advantages of Triac as Static … WebMost times, you can use the DIAC with the TRIAC circuits. And it’s because of the TRIAC’s shortcomings. That is, the TRIAC has a slight difference between the two halves of the device. Hence, the device doesn’t fire a circuit symmetrically. Due to the TRIAC’s non-symmetrical firing, the waveform produces the output with unwanted harmonics.

You can't just swap MT 1 and MT2 to move the load, you've got to connect the load between mains hot and MT2, the gate resistor from MT2 to the gate, and MT1 to mains neutral. But... the TRIAC might be toast. Test it by turning it on with a DC supply and load, and it should stay latched until you cut the power to the load.

WebTRIAC (Triode for AC) is a semiconductor device widely used in power control and switching applications. It finds applications in switching, phase control, chopper designs, brilliance control in lamps, speed control in fans, motors, etc. The power control system is designed to control the distribution level of AC or DC. WebTRIAC is equivalent to two SCRs connected in inverse parallel with the gates connected together. Therefore TRIAC works as a bi-directional switch which is triggered by the pulse on the base. The Main Terminal 1 and Main Terminal 2 of the TRIAC are used for connecting phase and neutral wire and the triggering pulse is supplied to Gate terminal ...
