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 T405-800T, +). Rule 4. To reduce the noise absorption SCR, gate connection length to a minimum. A return line directly to MT1 (or cathode) triac - Golden Rule isolated triac switch between MT1 and MT2 join RC snubber circuit. If high dICOM / dt can cause problems, add a few mH in series with the load inductance. Another solution, using Hi-Com triac.
