WebA multimeter can be used to test the health of a triac. First put the multimeter selector switch in a high resistance mode (say 100K), then connect the positive lead of multimeter to the MT1 terminal of triac and negative lead to the MT2 terminal of triac (there is no problem if you reverse the connection).
WebTRIACs. A TRIAC (triode for alternating current, also known as bidirectional triode thyristor or a bilateral triode thyristor) is a silicon semiconductor component with three terminals or legs that allow current to flow in either direction when triggered. TRIACs are a subset of thyristors and are similar to SCRs (silicon controlled rectifiers). Web21 jul. 2015 · A triac is a three-terminal, five layer semiconductor device whose forward and reverse characteristics are identical to the forward characteristics of the SCR. The three terminals are designated as main terminal MT 1, main terminal MT 2 and gate G. Fig.2 …
WebFigure 2 Triac layer construction and circuit symbol. The terminals of the triac are referred to as main terminal 1 (MT 1) and main terminal 2 (MT 2), owing to the fact that it is a bi-directional device and therefore really does not have an anode and a cathode. The gate …
