Triac - thyristor SCR T435-800T plastic measuring method in practical applications requiring the use of I +, I-, Ⅲ- three ways, and to I + and Ⅲ- the most widely used in two ways Controlled Silicon T435-600T, use the following two methods to discriminate SCR BT137S-600E, and the most common low-power triac triac Case - measuring method to determine the plastic SCR followed by T1 and G2 Red Table rod contacting T2, the black bar contacts bipolar any remaining one (for the time being assumed as T1) SCR, multimeter should display the red bar overflow then slide the other electrode (for the time being assumed to G), so that the red Stick shorting the two electrodes, if the display value is slightly lower than Ugt1 SCR BT137S-600E | SCR | n Wal Electronics Dongguan City is provided by Wal-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.
