Triac - Golden Rule isolated three triac rule 6. If the triac VDRM in serious abnormalities in the power supply instant process may be exceeded SCR, one of the following measures: series inductance of the load of several μH unsaturated inductance to limit dIT / dt; MOV jumper with the power supply, and increase the filter circuit triac on the supply side - the Golden Rule Isolated another three triac One solution: for resistive load zero voltage turn-on. Rule 9. SCR device fixed to the heat sink BT136S-600E, avoid triac subjected to stress. Fixed SMD SCR, then solder tails. Do not put the rivet mandrel piece on the side of the device interfaces. Rule 10. For long-term, reliable work, should ensure Rthj-a low enough to maintain Tj not more than Tjmax, whose value corresponds to the highest possible ambient temperature.
