What are the three terminal of a TRIAC

What are the three terminal of a TRIAC Correct Answer gate, anode 1 and anode 2

Triac:

  • A Triac is a bidirectional thyristor with three terminals i.e. it can conduct in both the directions.
  • Its three terminals are usually designated as MT1 (Anode 1), MT2 (Anode 2), and the gate by G as in a thyristor.
  • When in operation, a Triac is equivalent to two SCRs connected in antiparallel.
  • As the Triac can conduct in both the directions, the terms anode, and cathode are not applicable to Triac.
  • It is used extensively for the control of power in ac circuits.

 

The symbol and the i-v characteristics of Triac are shown below.

A triac may sometimes operate in the rectifier mode rather than in the bidirectional mode. This may happen due to the following reasons.

  • For a given value of positive gate current, a Triac may turn on with MT2 positive in the first quadrant but may fail to turn on with MT2 negative.
  • With constant negative gate current, the Triac may turn on with MT2 negative in the third quadrant but may not turn on with MT2 positive.
