BTB04600SL BTB04-600SL SCR press 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 60a, high-power multi-metal shell package SCR SCR bta26600b, while medium and small power thyristor is to use more plastic or ceramic package. TYN812 12A, 800V four-way thyristor structure P1N1P2N2 structure thyristor SCR shape no matter how they die is P-type and N-type silicon silicon composition. See Figure 1. It has three a PN junction (J1, J2, J3), from P1 layer structure leads J1 A thyristor anode, cathode leads from the N2 layer K, drawn from the P2 layer control electrode G, so it is a four-three-terminal semiconductor devices.
