How hot are triacs supposed to get?
I'm building a 936 clone soldering station, with the modification that the triac's gate is driven by an opto-triac with zero crossing, which is triggered by a comparator, since these are components I already have. I'm using a BTB04 triac, passing about 2 amps and it's dropping about a volt. So it gets pretty hot. The supply is 24VAC.
Are they supposed to have such a high voltage across them when conducting? Only I don't like that I'm losing 2W on it!
Thanks for looking
