Triac Triac Zhejiang Kun two crystal KS series designed for tablet / bolts (Lo ..

Triac is NPNPN five semiconductor material, the external also raises three electrodes. Triac equivalent of two antiparallel thyristors way, but only one gate. It works with unidirectional thyristor Triac, as also have trigger control features. However, it's a one-way thyristor trigger control characteristics are very different, and this is regardless of the polarity of the voltage between the anode and cathode access, as long as its control electrode coupled with a trigger pulse, regardless of the pulse What is polar, can make bidirectional thyristor. Since Triac in Shenyang, indirect cathode operating voltage of either polarity can trigger control, so the main electrode triac there is no anode and cathode of the points, usually referred to these two main electrodes T1 and T2 electrode electrode, It will be connected to the P-type semiconductor material called T1 main electrode electrodes, connected to the N-type semiconductor material called T2 electrode electrode. Since the two main electrodes triac no negative points, so it would be no arguments and counter with positive peak voltage peak voltage of the points, but only one maximum peak voltage, the other parameters of the triac and single identical thyristor. Although construction may be seen as a combination of two ordinary triac thyristor in form, but in fact it is more than just seven transistors and power resistors integrated device. Triac generally use low-power plastic packages, some also with a heat plate. Triac power they use RD91 package. Detection method, determination T1 pole seen from Figure, G very very close and T2, T1 very far away. Therefore, positive and negative resistance between G-T2 is very small. RXl profile with resistance measured between any two feet, only between the G-T2 exhibits low resistance, positive and negative resistance is only a few dozen in Europe, and T1-G, T2-T1 between the positive and the reverse resistance are infinite. This suggests that if a measure other legs and feet do not pass, it certainly is extremely T1. In addition, the use of TO-220 package Triac, T1 usually very little communication with the cooling plate, thus also determine T1 pole. After 2, the distinction between G and T2 pole pole (1) identify the T1 pole, first assume that the rest of the feet in a foot of T2 pole, the other foot for the G pole. (2) the black pen then T2 pole, the red pen then T1 pole, resistance is infinite. Followed by the red tip of the T1 and G short circuit to G pole with a negative trigger signal, the resistance value should be around ten in Europe, proved the tube has been turned on, the conduction direction of T2 a T1. Then the red tip and G pole disengaged (but still connected to T1), if the resistance value remains unchanged, proof tube after the trigger to maintain the conduction state. (3) the red pen then T2 pole, black pen then T1 pole, then T1 and G short for G-pole plus positive trigger signal, the resistance value is still about ten in Europe, after the G pole disconnected if the resistance is not change, then the tube after the trigger on T1 T2 direction a conducting state can be maintained, thus triggering a two-way nature. Thus proving that these assumptions are correct. Otherwise it is assumed that inconsistent with the actual need and then make assumptions, repeat the above measurements. Obviously, in recognition G, T2, in the process, also examined the ability to trigger the TRIAC. If it is assumed to measure according to which, do not make the TRIAC trigger conduction, proof tube to Pat damage. LA of the tube, can also be used to detect RXl0 files, 3A and 3A for more than a pipe, to be elected RXl file, otherwise it is difficult to maintain on state.
