Triac - thyristor connected differential voltage characteristic way junction J3 also breakdown SCR BT137S-600E, the current rapid increase in patch SCR, SCR start bending characteristics, such as characteristic OR segments are shown, voltage bends URO called "reverse breakover voltage." At this point, the SCR will be a permanent reverse. Triac - thyristor electron volt-ampere characteristic way into the N1 zone, the P2 zone holes. N1 electrons into the zone by the P1 region and the junction J1 through N1 injection hole recombination zone, also, into the region of the hole by the N2 P2 region by injecting electrons composite P2 J3 junction region, the avalanche breakdown thyristor T435 -600T, 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!
