Webb23 okt. 2024 · TRIACs are a subset of thyristors (analogous to a relay in that a small voltage and current can control a much larger voltage and current) and are related to silicon controlled rectifiers (SCRs). TRIACs differ from SCRs in that they allow current flow in both directions, whereas an SCR can only conduct current in a single direction. WebbThyristors are commonly used in control and automation applications due to their simplicity and great power handling capability, DIACs and SIACs are two-terminal electronic devices that conduct current in both directions and are turned on when the voltage across their terminals reaches the breakover voltage.
