Triac - Golden Rule Isolated Triac switch rule 2. To disconnect (switch) thyristor (or triac). Rule 3. When designing triac trigger circuit, whenever possible SCR BT136S-600E, is necessary to avoid the third quadrant (WT2- SCR BT137S-600E, +). Rule 4. To reduce the noise absorption SCR, gate connection length to a minimum. Return line is connected directly to the MT1 (or cathode) triac - product identification and transient disconnect A very switched on again, the pointer should be returned ∞ position, then the SCR is good. For 1 ~ 6A triac, red pen then T1 pole, while the black pen then G, T2 pole, to ensure black pen without departing from the premise T2 pole disconnect G pole, the pointer should indicate several tens to hundred Europe (depending on the current size of the SCR manufacturers vary) SCR T435-800T, being fertile Electronics (certified), SCR provided by the Dongguan City, is Wo Electronic Technology Co., Ltd.
