SCR advantage of small size, light weight, compact structure, high reliability, external line is simple, good interchangeability, ease of maintenance and installation; reproducible thyristor structure T405-600T, the mechanical design of the device can be simplified, price discrete devices and low advantages of SCR, which in a birth by the major power semiconductor manufacturers blitz, and thus has made rapid progress. SCR SCR There are several classifications. (A) press off, conduction and control Category: SCR off their conduction and control methods can be divided into ordinary thyristor, triac, reverse guide SCR, gate turn-off thyristor (GTO), BTG SCR, temperature and light control thyristor SCR other. (B) the pins and polarity classification: SCR their pins and polarity can be divided into two very SCR, three-pole and four-pole SCR SCR. (C) by Package Category: SCR can be classified according to their package SCR metal packaging, plastic and ceramic packages SCR SCR three types. Among them, the metal packaging SCR is divided Stud, flat-shaped, round shell-shaped other; plastic SCR is divided into finned heat sink type and without type two. Thyristor switch (four) by the current capacity classification: SCR can be divided according to the current capacity of high-power thyristor, the power and low-power SCR SCR three. Typically SCR 2P4M, high-power thyristor more metal shell package, while medium and small power thyristor is to use more plastic or ceramic package. (E) by off-speed Category: SCR turn-off speed can be divided according to their ordinary SCR and high frequency (fast) SCR. Zero trigger - generally transfer power, that is, when the AC voltage phase sinusoidal AC zero-crossing trigger, must be zero crossings only triggered thyristor conduction.
