Triac - voltage characteristic way thyristor when the voltage increases, the characteristics of the occurrence of a bend, as shown in the SCR segment characteristic OA BT137S-600E, the bend is called UBO: Forward breakover voltage, the voltage rise high to junction J2 after avalanche breakdown voltage, J2 junction avalanche multiplication effect of SCR, a large amount of electrons and holes in the junction region triac - way thyristor voltage characteristics and enter the e-N1 zone into the cavity of each P2 area can not all complex off thyristor T435-600T, so SCR T435-800T, have accumulated in electronic N1 zone, there is a hole accumulation in the P2 area, resulting in the potential of the P2 area liter high potential of N1 zone fell SCR BT137S-600E_ SCR _ positive Wal Electronics provided by 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.
