Triac - Measurement of red plastic bar table SCR short T2 and G, is displayed 0.546V (pipe conducting), a popular bar table from G show 0.558V poles, apparently SCR T405 -800T, the value is greater than the turn-on voltage of the SCR, but less than Ugt1, maintain the tubes in a conducting state. Upon detecting trigger performance opposite direction, very close to the results described above, the tube prove good performance. Triac - thyristor voltage characteristic way when voltage increases SCR BT137S-600E, characteristic bending occurs, such as the characteristics shown in paragraph OA SCR BT134W-600E, bend at the UBO called: Forward breakover voltage, the voltage is increased to the avalanche breakdown voltage after the junction J2, J2 junction avalanche multiplication effect occurs, resulting in a large number of junction electrons and holes thyristor, SCR, is fertile electrons from Dongguan City is fertile Electronic Technology Limited. 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!
