Triac - Package packages have used SCR TO-92, TO-126, TO-202AB, TO-220, TO-220AB, TO-3P, SOT-89, TO-251, TO-252 and so on. Triac - construction principles triac thyristor devices belong NPNPN five T405-800T, three electrodes are T1, T2, G. Because the device can double conducting thyristor BT134W-600E, so in addition to the two gate electrodes G collectively outside the main terminal, with T1, T2. Said that no longer divided into the anode or cathode. SCR BT136S-600E, SCR, are fertile Electronics Dongguan City is provided by Wal-Electronic Technology Co., Ltd.
