Triac - thyristor plastic measuring method (2) determine the triac trigger performance need to look at the working conditions in both directions, the following were introduced. Red Table rod connected thyristors T2 T435-800T, black bars connected to T1 SCR T435-600T, should appear overflow (OFF state). The red bar slide G SCR, and the T2 and G two poles turned triac - Measurement plastic SCR Found a TO-220 package Triac BCR3AM (3A / 600V) SCR BT137S-600E, first determine the electrode: red, black bars at the pipe between any two electrodes measure, when measured as 0.578V That Ugt1 when it is determined not in contact with a great bar table T2. SCR BT136S-600E_ SCR _ positive electrons provided by Wal Dongguan City is fertile Electronic Technology Co.
