Triac - thyristor plastic measuring method followed to determine T1 and G2 in contact with a red bar table T2 SCR BT137S-600E, the black bar contacts bipolar any remaining one (for the time being assumed as T1), multimeter should display overflow then slide the red bar the other electrode (for the time being assumed to G), so that the red bar shorting the two electrodes, if the display value is slightly lower than Ugt1 Triac - thyristor plastic measuring method (2) Trigger Performance discrimination Triac need to look at the working conditions of both directions SCR T435-800T, the following were introduced. Red Table rod connected thyristors T2, black bars then T1, should appear overflow (OFF state). The red stick slide G, and so these two poles turned T2 and G patch SCR | SCR | n 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.
