BTA24-600BW triacs are used in G3 controllers.So for my education.Why do these boards come with 24 amp triacs when each channel is rated at 8? Sounds like it's capable of up to 24 amps per channel max or the maximum that could be supplied to that side of the board. Link to comment Share on other sites More sharing options...
Ken Benedict Posted January 16, 2012 Share Posted January 16, 2012 Sometimes the startup current is many times the steady load for a very brief instant, quick enough to blow a triac.Consider it insurance.They make those triacs up to 40 amps, but the lead spacing is more spread out above the BTA24 versions.

Sounds like it's capable of up to 24 amps per channel max or the maximum that could be supplied to that side of the board.As mentioned it is for insurance BUT a good design never pushes components close to their limits. Beyond the rated current of 25 amps (the BTA24 is rated for 25 amps?) there are other numbers in the spec that are the main reason we moved to them. For example the BTA24 can handle a 260 amp, non-repetitive surge vs the BTA16's 168 amp.The ultimate goal is reliability.Dan Link to comment Share on other sites More sharing options...
