therealbigjim Posted December 31, 2014 Share Posted December 31, 2014 I think I have a bad trac, one channel is always on about 50%. anyone know the Mouser equivalent for the trac or a list of the part numbers for the cb16. I also have several boards with larger light leaks even with a snubber or incan string after a LED string. And because I did not use strain relief all but one of my boards have broken rj45 sockets. So I will be doing repairs on all 5 of my boards. Link to comment Share on other sites More sharing options...

a31ford Posted January 4, 2015 Share Posted January 4, 2015 (edited) the triacs are 400piv (at least) and 8-10 amp TO-220 package, ( IMPORTANT >)ISOLATED TAB (< Important) ALL TO-220 Triacs have the same lead config. 1 is output, 2 is input, 3 is trigger The DIAC in the optocoupler could be 1/2 blown (like the triac) both will give a 50% level HOWEVER, if it's the opto, the channel will turn off IF the opto is removed, where as it will stay on if it's the triac....... For the cost of 6 pin IC sockets... ALL my boards the opto is socketed.. Greg Edited January 4, 2015 by a31ford Link to comment Share on other sites More sharing options...
bob_moody Posted January 5, 2015 Share Posted January 5, 2015 You can order replacement triacs from Mouser or Digikey. I ordered from Mouserhttp://www.mouser.co...511-BTA16-600BW Hope this helps... Bob Link to comment Share on other sites More sharing options...
