Default Re: How much heat sink?

CarWiz ,Thats interesting about the light bulbs, Did you say that the filament temp is approx, 2500 degrees? thats quite a bit warmer than 125 degrees C that is the max junc temp allowed on the SSR, could be that would have something to do with feeling it sooner on the light bulb.You wrote that gas is a good insulation,but if you are familiar with a large utility generator, a lot of them use hydrogen gas internally as a conductor of heat(BTUs) circulating that gas thru coolers supplied with cooling water.
