Sorry this is off-topic! My pic is connected to a triac optocoupler(MOC3041) that drives a bigger = triac (IT615) which is rated at 600V 15Amperes.=20 When I switch 2.5KW heater element on at 220Volt the triac(IT615) with = heatsink becomes very-very hot. Must I get a higer rated triac or must I = look for some other problems? I am sure that the pic software don't switch the triac on/off the whole = time..It switch on at a certain time and off after a 5minute delay.
