Triac - construction principles Typical products BCMlAM (1A / 600V), BCM3AM (3A / 600V), 2N6075 (4A / 600V) SCR BT136S-600E, MAC218-10 (8A / 800V) and so on. Power triac mostly used RD91 package. Triac - SCR measurement methods make the red plastic stick with short T2 G SCR, is displayed 0.546V (tube conduction), a popular bar table from G show 0.558V poles, apparently, This value is greater than the turn-on voltage SMD SCR, but less than Ugt1 SCR, pipe in maintaining the conduction state. Performance in the detection of the trigger in the opposite direction, the results of the above is very close to the tube prove good performance. SCR T435-800T, are fertile Electronics (certified), SCR provided by the Dongguan City is Wal-Electronic Technology Co., Ltd. Dongguan City is Wal-Electronic Technology Co., Ltd.
