Triac - measurements show 0.546V plastic SCR SCR T435-600T the red bar at the short T2 and floating electrode, the voltage is less than Ugt1 = 0.578V, so black bars are connected to T1 SCR BT136S-600E, the other pole was G. Trigger Performance discrimination: the red bar then T2, then T1 black bars SCR T405-800T, display overflow (pipe off). Triac - thyristor connected differential voltage characteristic way junction J3 breakdown also rapidly increase the current, start bending characteristics, such as characteristic OR section, the voltage of the bend URO called "reverse breakover voltage." At this point, the SCR will be a permanent reverse. SCR BT134W-600E, SCR, is provided by Wal-electronic Dongguan City is fertile Electronic Technology Co., Dongguan City is Wo Electronic Technology Co., Ltd (www.dgmydz.com) (www.dgmydz.com) strong, credible, FET and other industries in Dongguan, Guangdong has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead positive fertile electronic and you hand into the brilliant, for a better future!
