Introduction. Parameter list for SCRs, Triacs, AC Switches, and Diacs. All datasheet parameters are rated as minimum or maximum values, corresponding to the product parameter distribution. In each datasheet, two classes of parameters are available: Absolute ratings, corresponding to critical parameters, not to be exceeded for safe operation.
This application note considers only noninsulated power supplies. After a brief description of the triggering quadrants and key parameters for SCR, triac, ACS and ACST, the usual control circuits are described according to the output voltage polarity of the power supply.

TRIACs. A TRIAC is basically two SCRs connected in parallel in opposing polarities with both gates tied together. TRIACs are used to control power in an AC circuit. It is a bidirectional electronic switch, which will conduct current in either direction when it is triggered with either polarity voltage on its gate.
18 sie 2021 · The TRIAC symbol is a simple circuit diagram that combines two equal SCRs in inverse parallel to each other. Also, the gates of the two SCRs merge to form a single gate. And there won’t be any current flow except there’s you inject a gate current pulse at G.
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.
