Supply of new RD-91 package BTA25-600B triac thyristor has a variety of 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. Between the electrode and the cathode of the SCR control is a PN junction, so it forward resistance around Europe in a few - a few hundred ohms scale, reverse resistance is larger than the forward resistance. But handling extremely diode characteristics are less ambitious, the reverse was not completely blocked condition, you can have a relatively large current through, therefore, sometimes measured manipulate very small reverse resistance SCR T405-600T, and can not very good handling characteristics clarify owe. In addition, in a very positive and negative control when measuring the resistance, the multimeter should be placed on R * 10 or R * 1 block, to avoid manipulation of extremely high reverse breakdown voltage. If the measured positive and negative elements of yin and yang is very short or very short-circuiting the anode and the manipulation or control electrode and cathode reverse short-circuit or open circuit SCR control electrode and cathode 2P6M, clarify elements are damaged. SCR sub-way thyristor SCR and triac two kinds C106G, all three electrodes. Way thyristor cathode (K), the anode (A), control pole (G). Equivalent to two single triac thyristor reverse parallel connection. During a way that the silicon anode and cathode of the other side of the company, said its terminals T2 pole SCR, during a unidirectional silicon cathode and anode connected to the other, said its terminals T2 pole, then the remaining manipulating pole (G). SCR 2P4M, are fertile Electronics (certified), SCR provided by the Dongguan City is Wal-Electronic Technology Co., Ltd. Dongguan City is Wal-Electronic Technology Co., Ltd.
