Judgment and T1 T2 G pole pole pole near SCR T435-600T, very far away from T2. Therefore, positive and negative resistance between G-T1 is very small. RXl file with resistance measured between any two feet, only between the G-T1 exhibits low resistance, positive and negative resistance is only a few dozen in Europe, and T2-G, are between T2-T1, reverse Resistors are infinite. This indicates that the SCR BT137S-600E, if measured a foot and other feet do not pass, it certainly is extremely T2. In addition, the use of Triac TO-220 package, T2 is usually very small cooling plate communicating with SCR, thus also determine a way thyristor T2 extreme pressure to monocrystalline silicon as the basic material of the three four-P1N1P2N2 terminal device, created in 1957, due to its characteristics similar to the vacuum thyristor SCR T435-800T, it is known as the silicon transistor gate international flow tube, called SCR T. Also, because the thyristor controlled rectifier initially applied to aspects of so called silicon controlled rectifier elements, referred to as SCR SCR.
