Transcript of Triac & Diac
Silicon controlled rectifier (scr/thyristor)
Diac & triacdiacA diac is a two-terminal semiconductor device that can conduct current in either direction when activated
diacDiac functions basically like two parallel 4 layer diodes turned in opposite directions
SCR working ( Case 1: Gate open )
Diac characteristic curve
TriacA triac is like a diac with a gate terminal
triacTriac basically functions like two parallel SCRs turned in opposite directions with a common gate terminal
