WebTRIAC can operate in four different modes. It has four layers of semiconductor. TRIAC can control both positive and negative half cycles of AC signal input. The TRIAC control DC as well as AC power. It is less reliable. It needs only one heat sink. Typically, most TRIACs are available in ratings less than 40 Amp and at voltages up to 600 Volt. WebIt has 5 layers of semiconductor. Capability. SCR can only control either positive or negative half cycle of AC input. TRIAC can control both positive and negative half cycles of AC signal input. DC Power. The SCR control DC power only or it can control forward biased half cycle of AC input in the load.
