Triac Schematics - A method of detecting extremely determination T2 be seen from Figure 6, G very very close to the T1, T2 very far away. Therefore SCR C106M, G-T1 between the positive and negative resistance 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 suggests that, if measured in a foot and other feet do not pass, it certainly is extremely T2. In addition, the use of TO-220 package Triac, T2 is usually very little communication with the cooling plate, thus also determine the T2 pole. 2. After distinguishing T1 G pole and pole (1) identify the T2 pole, first assume that the rest of the feet in a foot of Tl pole, the other foot for G pole. (2) the black pen then T1 pole, the red pen then T2 pole SCR C106D, resistance is infinite. Followed by the red pen to T2 and G short for G-pole with a negative trigger signal, the resistance value should be around ten Euro (see Figure 6 (a)), prove that the tubes have turned SCR 2P4M, conduction direction T1 a T2. Then the red pen and G pole disengaged (but still connected to T2), if the resistance value remains unchanged, prove tubes can be maintained after the trigger conduction state (see Figure 6 (b)). SCR basic voltage characteristics (1) Open-reverse feature when the control anode coupled with reverse voltage, J2 junction is forward biased, but the J1, J2 junction reverse biased. At this point only flows through the small reverse saturation current, when the voltage is further increased to J1 junction avalanche breakdown voltage, then the difference between junctions J3 also breakdown, the rapid increase in current, start bending characteristics, such as the characteristics shown in paragraph OR The voltage of the bend URO called "reverse breakover voltage." At this point, the SCR will be a permanent reverse SCR C106D | are fertile Electronics (certified) | SCR Dongguan City is provided by Wal-Electronic Technology Co., Ltd.
