Bidirectional thyristor is developed on the basis of the ordinary thyristor, it not only can take the place of two parallel SCR, reverse polarity and requires only a trigger circuit, is ideal ac switching devices. What should the bidirectional thyristor classification? Explanation: for you, A) According to shut off, conduction and control methods of classification: the bidirectional thyristor according to the shutoff, conduction and control methods can be divided into ordinary thyristor, bidirectional thyristor, inverse, the gate turn off thyristor (silicon controlled rectifier GTO) , BTG thyristor, temperature control thyristor and electric silicon controlled rectifier, etc. ( 2) Classified by pins and polarity: two-way thyristor according to its pin and polarity can be divided into diode, triode thyristor silicon controlled rectifier and quadrupole SCR. ( 3) According to the classification packaging format: two-way thyristor according to its packaging forms can be divided into metal silicon controlled rectifier, encapsulation of SCR and ceramic packaging thyristor three types. Among them, the metal packaging SCR is divided into bolt shape, flat shape, round shell, etc; Encapsulation SCR is divided into with fin type and without fin type two kinds. ( 4) According to the current capacity classification: two-way thyristor according to the current capacity can be divided into power in the high power thyristor, thyristor and small power thyristor three. Usually, high power thyristor with metal shell encapsulation, while the medium and small power thyristor used more powder coating or ceramic package. ( 5) According to shut off the speed of classification: two-way thyristor according to its off speed can be divided into ordinary thyristor and high frequency ( Fast) Silicon controlled rectifier. Two-way if interested in our two-way thyristor module or there is doubt, welcome your consultation.
