Triac - product identification for one-way SCR, closing the switch K, lights should be lit, disconnect K lamp still quench otherwise explain SCR damage. For triac plastic packaging, closed switch K, lights should be lit, disconnect K, lights should not be quenched. Then reverse battery Taiwan-funded factory blister packaging, repeat the above steps, the result should be the same plastic, only explanation is good. Otherwise, it means that the device has been damaged Triac - thyristor plastic measuring method (1) determine the electrode is first determined T2: two casual contact with the tube bar table any two electrodes Dongguan plastic packaging suppliers, and in turn change connection until you find the display is 0.1 ~ 1V (herein referred to as the voltage drop between Ugt1 T1 and G), the vacant electrode is T2.
