Triac Schematics - aka "Triac" triac is a kind of monocrystalline silicon base material for P1N1P2N2 four three-terminal device SCR C106G, is developed on the basis of which the ordinary SCR SCR AC switch devices into T405-600T, whose English name that triac TRIAC AC switch of Italy, was invented in 1957. Triac unidirectional conductivity switch can replace two parallel SCR reverse polarity, and only a trigger circuit. SCR has a turn-on and turn-off of two states, to distinguish from the appearance are: bolt-shaped, flat-shaped and flat-bottom shape categories. Because triac thyristor characteristics similar vacuum, so called silicon transistor gate through the international flow tube, called SCR T; and because thyristor controlled rectifier aspects initially applied to SCR 2P6M, so called silicon controlled rectifier elements, referred to as SCR SCR. SCR basic voltage characteristics (1) Open-reverse feature when the control anode coupled with reverse voltage, J2 junction is forward biased, but the J1, J2 junction reverse biased. At this point only flows through the small reverse saturation current, when the voltage is further increased to J1 junction avalanche breakdown voltage, then the difference between junctions J3 also breakdown, the rapid increase in current, start bending characteristics, such as the characteristics shown in paragraph OR The voltage of the bend URO called "reverse breakover voltage." At this point, the SCR will be a permanent reverse SCR 2P4M, are fertile Electronics (certified), SCR provided by the Dongguan City is Wal-Electronic Technology Co., Ltd.
