nec 2P4M way thyristor 2A, 400V, Dongguan, Zhongshan factory wholesale triode thyristor minutes from the main spiral shape, three flatbed peaceful hearth, spiral used more often. There are three SCR --- anode electrode (A) of the cathode (C) and a control electrode (G). It has a four-layer structure of the die is P-type and N-type conductor overlap conductor consisting of a total of three PN junctions. SCR and only one PN junction silicon rectifier two extreme tube structurally different. SCR four-layer structure and the control electrode of reference for its play "with little control big" excellent control characteristics of the foundation. In the application of thyristor SCR C106G, as long as the control electrode coupled with small current or voltage, can control a large anode current or voltage. Current capacity of up to several hundred or even thousands of amperes amps thyristor. Generally kept below 5 amps power thyristor SCR petit, more than 50 amps power SCR SCR call. Single SCR, triac discrimination: first one of the two test poles SCR T405-600T, if the positive and negative test pointer not moving (R × 1 block), may be A, K or G, A pole (unidirectional SCR) may be T2, T1 or T2, G pole (for triac). If one has a measurement instructions for tens to hundreds of European SCR, it certainly is way thyristor. And a red pen for the connected K-pole, black pen then for G pole, and the rest is the A pole. If the positive and negative test instructions are tens to hundreds of Europe, certainly for the triac. Then dial knob to R × 1 or R × 10 block retest, which must have a resistance slightly SCR 2P4M, the slightly larger one red pen then for G pole, black pen connects to T1 pole, The remaining is T2 pole.
