Triac - Product identification 1, single, triac discrimination: first one of the two test poles SCR BT136S-600E, if the positive and negative test pointer not moving (R × 1 block) SCR T435- 600T, may be A, K or G, A pole (on the way thyristor) may be T2, T1 or T2, G pole (for triac). Triac - Golden Rule Isolated triac switch between MT1 and MT2 join RC snubber circuit. If high dICOM / dt can cause problems, adding a few mH inductance and series with the load. Another solution, using Hi-Com triac. SCR BT134W-600E_ are fertile Electronics (certified) _ SCR Dongguan City is provided by Wal-Electronic Technology Co., Ltd.
